Abstract
Purpose
The study considers time-varying risk premium in investigating the capability of technical analysis (TA) to predict and outperform a buy–hold strategy in Bitcoin exchange rate returns.
Design/methodology/approach
The study tests the technical trading rule of fixed moving average (FMA) on daily actual and equilibrium returns of Bitcoin exchange rates. The equilibrium returns are computed using dynamic CAPM in conjunction with a VAR-MGARCH (1, 1) system. The empirical evaluation of the study uses a case study of four Bitcoin exchange rates (BTC/AUD, BTC/EUR, BTC/JPY and BTC/ZAR) for the period 19 June 2010 to 30 October 2020.
Findings
The findings are consistent with related studies in conventional foreign exchange markets that find TA to be profitable, especially in emerging markets. Nevertheless, the consideration of risk premium has the effect of reducing the abnormal returns. Also, further robust tests reveal that Bitcoin returns possess a momentum effect which prompts further study in efficient market hypothesis research.
Practical implications
The empirical findings of this study should benefit portfolio managers and active investors on the strength of TA to predict returns in a speculative market like the Bitcoin exchange rate market.
Originality/value
The study takes cognisance that cryptocurrency trading is speculative in nature which renders it a good candidate for TA methods. While there are studies that have explored the value of TA in Bitcoin exchange rates, these studies fail to incorporate the effects of time-varying risk premiums, the strength and focus of the current paper.

1. Introduction
Over the years, academics and practitioners have demonstrated an overwhelming interest in the profitability of technical analysis (TA) on practically all financial systems and assets. Historical evidence indicates that technical trading strategies were profitable in foreign exchange markets and future markets (Smidt, 1965; Sweeney, 1986; Taylor, 1986), but not in stock markets (Fama and Blume, 1966; Van Horne and Parker, 1967). More recent empirical studies suggest that technical trading rules (TTRs) may generate positive profits in certain speculative markets, most notably in foreign exchange and futures markets (Nazário et al., 2017). Various theoretical and empirical explanations have been proposed for TA-based profits. From the investment theory perspective, Neely et al. (2014) suggest that abnormal profits based on TA trading may arise because of market “frictions”, such as noise in current equilibrium prices, traders' sentiments, herding behaviour, market power or chaos. Other possible explanations for the persistence of trading profits are the presence of central bank interventions (particularly in foreign exchange markets), order flow, temporary market inefficiencies, risk premiums, market microstructure deficiencies or data snooping (Park and Irwin, 2007). Regardless of the origin or description of profits, the current study only asks the question of whether TA trading is profitable, particularly in the Bitcoin case.
Cryptocurrencies may show connectedness to currency markets more than stock, and this means they may mimic some of the characteristics that make the foreign exchange market attractive to TA users. Extant literature shows that researchers have investigated the profitability of TTRs in a variety of markets for the purpose of either uncovering profitable trading rules or testing market efficiency, among other things. However, sufficient in-depth analysis of the cryptocurrency market is still lacking, so that the stylised facts of related TA benefits are yet to be understood. The current study contributes towards closing this knowledge gap. The objective of this paper is to investigate the profitability of TA on four Bitcoin exchange rates (BTC/AUD, BTC/EUR, BTC/JPY and BTC/ZAR) after accounting for time-varying risk premiums. Furthermore, the study evaluates the presence of a momentum effect in Bitcoin exchange rates. While most papers focus on Bitcoin as an individual currency (Urquhart, 2016; Bariviera, 2017; Khuntia and Pattanayak, 2018; Kristoufek and Vosvrda, 2018; Tiwari et al., 2018; Sensoy, 2019), the current study investigates the TA profitability in four Bitcoin exchange rates for comparison and breadth. The current study extends and deepens the research on TA usage in foreign exchange markets (Kho, 1996) to cryptocurrency exchange rate. This study will test TA profitability in Bitcoin by employing 24 Fixed Moving Average (FMA) techniques.
The observed results were compared to a buy–hold strategy accordingly, and a significant difference was noted. The study's findings indicate that the chosen TTRs' strategies outperform the buy–hold strategy. A portion of the reported gains can be accounted for by time-varying risk premiums, as profits decline when risk is included. In view of the current and related studies, it is evident that Bitcoin may be an ideal laboratory for experimenting with TA since it lacks discernible fundamentals. The study advanced a novel stylised fact, indicating that the MA trading rule can forecast Bitcoin returns even when time-varying risk premiums are taken into consideration.
The remainder of this paper is structured as follows: Section 2 provides a literature review, Section 3 introduces the historical background of Bitcoin as a cryptocurrency, Section 4 describes Bitcoin's possible candidature of TA, Section 5 outlines the data and methodology utilised in the study, Section 6 presents the empirical results, Section 7 presents a discussion of results and Section 8 concludes the study.
2. Literature review
2.1 Related studies
According to the efficient market hypothesis (EMH), stock prices fully contain all relevant market information. This means that any new information should be reflected in the security prices as soon as it becomes available. To classify the type of information captured by stock prices, there are three classes of market efficiency: (1) strong form like private firm information, (2) semi-strong form such as published economic statistics and financial statements, as well as (3) weak form which is primarily historical security prices and trading volume. Gerritsen et al. (2021) discovered that Bitcoin price behaviour has intertemporal predictability, implying that investors may estimate future gains. Trading rules based on past data should not be successful according to weak-form market efficiency. TTRs such as filter rules (Alexander, 1961, 1964; Fama and Blume, 1966; Sweeney, 1988), relative strength rules (Levy, 1967; Jensen and Benington, 1970; Brush and Boles, 1983; Jacobs and Levy, 1988) and moving average trading rules (Van Horne and Parker, 1967; Dale and Workman, 1980) have been shown in earlier empirical studies to be unable to perform better than the traditional buy–hold strategy, and that any predictive variation in security returns is statistically and economically insignificant.
Recent research, on the other hand, has shown that simple trading strategies can be useful in predicting stock market returns. For example, an influential TA study by Brock et al. (1992) investigated two simple TTRs, namely, Moving Average (MA) rules as well as Trading Range Breakout (TRB) rules, and found that these two simple rules had considerable predictive power for the US equity index returns. These results were extended and confirmed by Bessembinder and Chan (1998) using US data, and Bessembinder and Chan (1995) using data from Asia–Pacific stock markets. The studies made an important observation that TA has less explanatory power in the more developed markets, but is more successful in emerging markets (Ito, 1999; Ratner and Leal, 1999; Miller et al., 2019; Grobys et al., 2020). Therefore, TA profitability (or its possibility) may be seen as one of the EMH anomalies arising from weak form efficiency.
Regarding the cryptocurrency market, the focus area of the current paper, there are several studies that have explored the implications of TA or its relevance in investment analysis. Miller et al. (2019) examined an identification technique in automated price patterns for Bitcoin cryptocurrency based on 1-min price data. The research examined several well-known TA patterns and developed trading procedures for and evaluated the effectiveness of selected trading strategies. The findings indicate that employing smoothing splines to deduce TA patterns has several advantageous and promising methodological properties. Additionally, the study discovers that methods based on certain TA patterns outperform the traditional buy-and-hold approach. A related study by Grobys et al. (2020) examined simple moving average trading strategies utilising daily price data from 2016 to 2018 for the 11 most-traded cryptocurrencies. Their findings indicated that the variable moving average technique is effective. When the average market return is considered, the TTR remains beneficial.
In a parallel study, Resta et al. (2020) used trend-following and mean-reverting techniques and found supportive results for the TA method when investigating the profitability of TTRs in the Bitcoin market. Using daily and five-minute interval data, their study period covered 1 January 2012 to 20 August 2019. Generally, the study concluded that daily trading data is more successful than trading intraday data. More meaningfully, the study revealed that simple Moving Averages techniques are superior when dealing with daily data. This study supports Gerritsen et al. (2020), who find TTRs to be more cost-effective than the buy–hold strategy when dealing with daily Bitcoin data. Other studies that reach favourable conclusions regarding the benefit of TA in cryptocurrency exchange rates include Tiwari et al. (2018), Miller et al. (2019), Gerritsen et al. (2020), and Detzel et al. (2021).
Given the increasing interest in cryptocurrency markets, including the spread into central bank digital currency, it is evident that the cryptocurrency market is enduring. The current study incorporates developments in the literature and expands knowledge on Bitcoin and TA profitability using more recent data, while applying the wisdom of tested techniques suggested by Brock et al. (1992) and Kho (1996).
2.2 Hypotheses
The current study examines three hypotheses to guide empirical investigation for TA profitability on four Bitcoin exchange rates (BTC/AUD, BTC/EUR, BTC/JPY and BTC/ZAR). The first hypothesis (hereafter coded, H1) states that when the mean returns derived from TTR are tested respectively on both equilibrium and actual returns, they are not different from the mean returns of normal trading days (buy–hold strategy). Simply put, this means that the buy (sell) returns of TTRs should not be different from the returns of normal trading days when there are no trading signals. The second hypothesis (H2) states that there is no difference in means between the buy and sell spread. This implies that if TTRs are not profitable, then the study should find no significant difference between the buy-and-sell returns. The next hypothesis is based on the momentum effect. Momentum is the rate of change of security prices or returns. If the rate of change of returns is high, momentum is regarded to be strong; if it is low, momentum is believed to be low (Jegadeesh and Titman, 1993; Gharaibeh et al., 2021), and these patterned changes are exploitable for the predictability of security returns (Chan et al., 2000). Therefore, the third hypothesis (H3) states that there is no relationship between price movements and return fluctuation (momentum effect). That is, the test enquires if further increases or decreases are associated with respective buy and sell signals.
3. Bitcoin's operational design
Bitcoin was birthed out of the concept of cryptocurrency which dates back to the 1980s when David Chaum wrote a seminal chapter on blind signature cryptographic primitives (Chaum, 1983). The author then proposed a useful cryptographic approach for application in safe digital currency transmissions. Cryptography, as defined by Harwick (2016), is a mechanism for creating virtual “money” and ensuring its secure ownership and transaction through the application of a cryptographic problem. Since its inception in 2009, Bitcoin as the first cryptocurrency has experienced both volatile and calm fluctuation over time.
Bitcoin is a decentralised digital currency system that is operated with blockchain technology. The production of Bitcoin is associated with a “mining” process (an equivalent of minting in fiat money), in which miners (or peers) use computers to create new Bitcoins by solving complex mathematical problems known as a proof of work or consensus method. Miners are rewarded with portions of Bitcoin for each Bitcoin created (Cheah and Fry, 2015). The Bitcoin structure is intended to remain unchanged from inception until the last Bitcoin is mined. The Bitcoin cash system is designed with a total capacity of 21 million (Shakya et al., 2021). At the time of writing, there are 18,361,438 Bitcoins in circulation, leaving just 2,638,562 Bitcoins to be mined over the next approximately 119 years (Gandal and Halaburda, 2016). In view of the well-defined capacity and monetary system of Bitcoin, it is reasonable to conclude from the explained rules and empirical evidence (Gopane, 2019) that the worth of Bitcoin is remote from fundamental valuation. This creates a space for fundamental-free or speculative methods like TA to find direct opportunities for experimentation.
4. Bitcoin's speculative nature and technical analysis
The recurring characteristic of speculative assets, like Bitcoin, throughout history, has been due to their inability to be valued and/or unpredictable bubbles. Tulipmania, the South Sea Bubble, and others all signal speculation on one hand, and the difficulties of assigning an objective value to a speculative asset on the other (Garber, 1990). All speculative behaviours have been reflected in the exponential growth of the Bitcoin time series (Bariviera et al., 2017). Bitcoin lacks savings accounts and, as a result, no lending interest rates. The implication is that economic knock-on effects and spillover shocks are severely constrained or inapplicable. Consequently, the trails of fundamental analysis valuation are disabled significantly. Empirical assessment by Ciaian et al. (2016) finds that there are no macroeconomic indicators influencing Bitcoin's price, but they do not rule out the possibility that investor speculation has a major impact on the price development. The attraction of Bitcoin as an investment opportunity is significant in financial markets (Dyhrberg, 2016; Bouri et al., 2017) and this raises the need for appropriate price valuation methods that are empirically tested. In the instance of fundamental analysis irrelevance for Bitcoin, TA tools become a viable possibility. Therefore, the current study examines the profitability of technical trading methods and whether they are feasible alternatives as an analytical tool to evaluate Bitcoin exchange rate returns.
5. Data and methodology
The research method in this study is quantitative and utilises several econometric equations, but the primary models are dynamic CAPM and VAR-GARCH. The modelling approach is explained later. First, we describe data collection and pre-validation procedures. The secondary dataset was sourced from the IRESS (2017) database and Bitcoincharts (n.d.). The frequency of the time series is daily and covers the period between 19 July 2010 and 31 October 2019. For empirical modelling purposes, the price data is converted into logarithmic returns through Eqn (1):
Table 1 summarises the time series used in the study and preliminary data validation. Judged by the positive means and stable standard deviations, the variables are comparable which is a useful feature in econometric analysis. The observation on the Jarque–Bera test, kurtosis and skewness reveals a typical phenomenon of financial time series (Brooks, 2014) of being skewed (positively or negatively) and peaked around the mean (leptokurtic). Other pre-validation tests performed on the data include Augmented Dickey–Fuller (ADF), which confirms that all variables are stationary which is desirable in regression analysis.
5.1 The design of technical analysis trading rules
The study employs 24 FMAs. The Moving Averages (MAs) were chosen because they are the most popular TTRs. Two types of MAs are used to produce buy-and-sell signals: a short-period average and a long-period average. In its basic design, this system is described as a buy
The study, however, uses FMAs and holds signals for ten days before closing and re-entering the market. The ten-day holding period separates the FMA from the variable moving average (VMA), where positions are taken every day as signals are generated. These trading rules are in line with usage in Kho (1996) and Brock et al. (1992). The procedure helps minimise the possibility of statistical bias. The TTRs based on FMA are modelled using econometric models to assess the profitability of TA.
5.2 Econometric models
The study applies TA rules to two sets of Bitcoin exchange rate returns, namely, actual returns and equilibrium returns. The latter are computed using dynamic CAPM. In this modelling, and to make beta dynamic, the study employs the multivariate generalised autoregressive conditionally heteroscedastic (MGARCH) system.
5.2.1 Modelling equilibrium returns using dynamic CAPM
In cryptocurrency and capital market studies (Bouri et al., 2020; Nugroho, 2021) there is a continual realisation that dynamic asset pricing modelling have a greater benefit over static models. The constant risk premium, or the static CAPM such as used by Sweeney (1986), is not deemed a suitable benchmark model for testing the trading rules' profitability because the risk of TA on the original series cannot essentially be comparable to that of the equilibrium strategy, among other things. Therefore, dynamic CAPM is the preferred model specified in Eqn (4):
In Eqn (4), the subscript
The parameters and standardised residuals are estimated using the maximum likelihood method. In the VAR(p) system (Eqn (6a)),
To recapitulate, in tandem with Kho (1996) the dynamic CAPM (in Eqn (4)) is a mathematical formulation of log returns (Eqn (1)), and conditional beta (Eqn (5)) which is based on VAR-MGARCH system (Eqs (6a) and (6b)). Eqn (5) is a well-known relation of beta (see Brooks, 2014) and effectively captures covariation of Bitcoin exchange rates with the MSCI benchmark (introduced earlier). There are a few reasons why MSCI is deemed a viable proxy for global financial markets including cryptocurrency. First, virtual currencies are global in nature so the benchmark should have international positioning. Second, in the absence of a proved global index for cryptocurrency the literature (Neely et al., 1997) shows that MSCI is a reasonable benchmark for foreign exchange market and by extension a close approximation or relevance for Bitcoin exchange rates in the current study. Other advantages of MSCI as a global benchmark is that it is widely applied in practice (Hsu et al., 2010; Bena et al., 2017) and academic research (Neely et al., 2009; Bouri et al., 2020), thus giving confidence for empirical usage. Another important feature of MSCI index is that it includes both large and small stocks thus mitigating the considerations of tradability and liquidity (Sermpinis et al., 2021).
5.2.2 TA profitability: BLL's mean difference test
The Brock et al. (1992) (abbreviated, BBL) methodological approach is employed to study TA's individual (buy, sell and buy–hold strategy) mean returns. Brock et al. (1992) utilise the mean returns of trading rules and their respective t-statistic. The idea is to test the profitability of TA by comparing the difference between the conditional and unconditional mean returns from TA. The same technique is employed but with a robust approach instead of using the return on the buy–hold strategy. The return on days when no trading signal is emitted is represented by
5.2.3 TA profitability: Kho's mean-spread test
The objective of Eqn (8) is to test hypothesis H2, whether the spread between buy and sell signals is equal to zero. This special regression equation was first utilised by Cumby and Modest (1987) in a market-timing study. This test equation was first applied by Kho (1996) in TA profitability investigation. For this reason, we label Eqn (8) as Kho's mean-spread test for identification and simplicity. This equation is similar to Eqn (7), but it has advantages of validating the regression analysis with robust standard errors (Newey and West, 1987). Empirically, if the spread equals zero, it will mean that the buy and sell signals are equal. This would be a case against TA profitability. Based on the framework of Eqn (8), then if the spread is zero, the coefficient,
In Eqn (8),
5.2.4 Time-varying risk premium and actual returns
The modelling objective of unconditional and conditional CAPM is to compare the equilibrium returns from both models based on the outcomes of buy and sell signals (TTRs). “If markets are efficient and the assumed model of asset pricing [CAPM] is correct, the technical rule returns in excess of the time-varying expected returns should have a zero conditional mean” (Kho, 1996, p. 279). This means that there should be no difference between expected returns under the two models. However, if the unconditional model outperforms the conditional model (or equal performance) it can be concluded that the abnormal profits derived from TTR are only reflecting time-varying risk premium. That is, investors who find TA profitable are merely compensated for their risk-bearing abilities. One way to determine the statistical significance of whether time-varying risk premium influences TTRs is to apply the standard t-test on the difference between the unconditional and conditional returns from TTR and examine if the spread is different from zero (Kho, 1996).
5.2.5 Consistency and robustness check
A robustness check in this study will examine the link between daily returns on Bitcoin and signals generated by the trading rules used (hypothesis H3). TA assumes that investors follow signals emitted at time
In Eqn (9),
6. Empirical results
This section presents the results of the paper. That is, an evaluation of the study hypotheses, H1, H2 and H3, relating to the mean-difference test (Eqn (7)), spread test (Eqn (8)) and momentum test (Eqn (9)), respectively. In addition, the analysis of risk premium and its implication in the results are elaborated. Before explaining the study results, it is important to provide a comprehensive report on post-estimation validation of the models in light of relevant econometric theories.
The practical timeseries regressions are generally affected by heteroscedasticity and autocorrelation problems regarding the BBL Model (Eqn (8)) and Momentum Effect test (Eqn (9)). For this reason, the Newey and West (1987) robust standard errors are utilised to ensure the fitness of regression analysis. Further diagnostic procedures, including the ARCH-LM test, were applied to ensure that all the ARCH effects are fully modelled in the BEKK-MGARCH model (Eqn (6)).
6.1 TA profitability assessment based on dynamic CAPM
Based on a test of the 24 TTRs (listed in Table A1, in Appendix) using the dynamic CAPM model, the results of each exchange rate (BTC/AUD, BTC/EUR, BTC/JPY and BTC/ZAR) are reported separately in Tables 2–5, respectively.
6.1.1 BTC/AUD exchange rate
In what follows, we report on TA performance based on the returns of moving average rules applied on conditional CAPM for BTC/AUD exchange rate.
Based on BBL's mean difference test, the results in Table 2 compare TA generated trades to those of buy–hold strategy. The average number of buy and sell signals is 68 and 175, respectively. The findings on 24 trading rules tested show that all buy signals are significantly different from the buy–hold strategy at 1% level, while just under 80% of the sell signals are significant at conventional levels. This means that while buy signals yield better results than sell signals, they both outperform the buy–hold strategy. There are other noteworthy factors to observe in the results.
The trading rule that stands out is trading rule number 10, which is designed as (2,50,1) meaning 2 short days, long-moving average of 50 days and a premium band of 1% (hereafter and for convenience trading rules will be cited as TTR No. #, as sequenced in the result tables). TTR No. 10 produces 223 sell signals with average return of −0.12% compared to the 20 buy signals with the highest average daily returns of 1.5%. These returns are statistically significant at 1% level. Further, all the indicated 20 buy signals produce positive returns, while only 44% of the 223 sell signals achieve returns greater than zero (columns 8 and 9). Other trading rules that produce relatively high buy returns which are significantly different from the sell returns are TTR No. 5 (5,20,0) and TTR No. 20 (1,200,1). Thus, contrary to Brock et al. (1992) who note that profits derived from trading rules depend on the number of signals, even if there are fewer buy signals, it is discovered that the buy return is higher than the sell return.
On aggregate, the standard deviations of buy signals (column 5) and neutral or buy–hold strategy (column 6) are comparably higher than the sell signals (column 7). This implies that while the buy trades are riskier relative to sell signals, these buy signals are no riskier than the market. The average fraction of buy and sell returns (columns 8 and 9), which are above zero, are 87 and 35%, respectively. The daily mean returns for buy, buy–hold and sell are 0.9%, −0.01% and −0.2%, respectively (columns 10, 11 and 12). The buy returns are substantially different and higher than both the buy–hold and sell returns. To summarise, the above indicate that if the TA method were applied to BTC/AUD during the period under investigation, the TTR would have yielded returns' profitability better than that of a buy–hold strategy.
6.1.2 BTC/EUR exchange rate
The results of moving average rules based on conditional CAPM for the BTC/EUR exchange rate are reported in Table 3 and are discussed next.
An observation of the results in the context of the BBL's mean difference test shows that TA may be profitably used in the BTC/EUR exchange rate. The evidence for this finding is that out of the 24 tested trading rules, 96% (column 15) of the buy signals are strongly significant at 1% level. In addition, the sell signals are less impactful than buys, but 63% (column 16) of the executed experimental sell trades are significant. Furthermore, an overview of the rest of the table reveals other interesting insights. There are 180 sell signals compared to 63 buy signals, yet the buy trades outperform the sell (columns 3 and 4). For instance, a glance at columns 8 and 9 shows that there are significantly more returns that are greater than zero for the buy signals (averaging 66%) compared to the sell signals with an average of only 12%. Another example, TTR No. 6 (5,20,1) stands out in that it produces the greatest number of sell signals (of 240 trades) and it yields only three buy signals. The average daily mean returns for buy, buy–hold and sell trades are 0.3%, −0.5% and −0.7%, respectively (columns 10, 11 and 12). Again, it is noticed that the buy signals produce the highest return. Overall, the results show that the TA method is equally successful when applied to BTC/EUR. Nevertheless, it is also useful to observe that the results of BTC/EUR are less strong than BTC/AUD.
6.1.3 BTC/JPY exchange rate
The moving average rules results applied to conditional CAPM for the BTC/JPY exchange rate are shown in Table 4 and explained next.
The results of the BBL's mean difference test show that the TA method may be profitably applied to the BTC/JPY exchange rate. The evidence of this finding is based on the observation that out of the 24 tested trading rules, 23 buy signals are strongly significant at 1% level (column 15), while 67% of the experimented sell trades are significant at conventional levels (column 16). The background details also tell an informative story. In the total of 248 experimental trades from buy and sell signals, only 28% were generated by buy signals, yet the buy trades performed distinctly better with average returns of 73% compared to 21% of sell signals (see columns 8 and 9).
According to the above evidence, the average number of buy and sell signals for BTC/JPY is 69 and 179, respectively (columns 3 and 4). Again TTR No. 6 stands out as the TTR with the least buy signals but highest number of sell signals. Buy, sell and buy–hold have average standard deviations of 0.009, 0.003 and 0.007 (columns 5, 6 and 7) and daily mean returns of 0.5, −0.3 −0.5% respectively. Therefore, the buy signal is more profitable than the sell and buy–hold strategy, but at slightly higher risk. Overall, the results support the efficacy of the TA method.
6.1.4 BTC/ZAR exchange rate
The findings of moving average rules based on conditional CAPM for the BTC/ZAR exchange rate are displayed in Table 5 and are discussed next.
Unlike Bitcoin exchange rates discussed above, BBL's mean difference test shows that TTR signals are individually significant at conventional levels but cannot be called profitable. The last row of the table shows that in the total trades of 244 (63 + 181) from the 24 trading rules, the buy, buy–hold strategy and sell trades yield an average standard deviation of 0.006, 0.007 and 0.003, compared to mean returns of 0, −0.7 and −0.8%, respectively. This implies that while the risk measure is comparable to other Bitcoin exchange rates, the mean returns are eliminated.
From the findings above (in Tables 2–5), it can be observed that the efficacy of TA is emphasised more in economies that appear to be cryptocurrency-friendly or have positively explored the market with adoption possibilities into mainstream finance (BTC/AUD and BTC/JPY). Evidence of diminishing profits is found in BTC/EUR and BTC/ZAR. The results associated with BTC/EUR may be because of Bitcoin's becoming more efficient. The profits are entirely erased in the case of BTC/ZAR, where the official national position on cryptocurrency is rather unreceptive. Another reason why TA fails to yield profitable performance in the South African Bitcoin market (BTC/ZAR) is that the market itself is under-developed. Some believe that if there is influx of uninformed technical traders into a market, this may derail the technical strategy's power. The study's findings reveal that sell signals are more volatile than buy signals, which provide evidence that profits derived from TTR are not only compensation for risk.
6.2 Results of Kho's mean-spread test
The results of Kho's mean-spread test based on Eqn (8) are presented in Tables 6 and 7. These tables provide a report on the average spread between the conditional buy and sell signals along with their respective t-statistics. The tests in these tables are conducted under the null hypothesis that the spreads are not statistically different from zero. The t-statistics are computed using Newey and West's (1987) robust standard errors.
6.2.1 BTC/AUD and BTC/EUR exchange rate
Table 6 reports the results of Kho's buy–sell mean-spread test. The first two columns are tabulation and definition of rules. The first panel (columns 3 to 7) displays the results for BTC/AUD, while the second panel (columns 8 to 12) shows results for BTC/EUR.
The results of Kho's buy–sell mean-spread test provide enough evidence to reject the null hypothesis [H2] that the buy–sell spread is not different from zero, and we conclude that the buy signals differ from sell signals. Based on the 24 moving average trading rules that are tested, 54% of BTC/AUD are statistically significant at conventional levels, while all the TTR's for BTC/EUR are strongly significant at 1% level. The rest of the table provides other supportive information. Eqn (8) is a special test equation (not conventional regression analysis) and as such the
6.2.2 BTC/JPY and BTC/ZAR exchange rate
Table 7 reports the results of Kho's buy–sell mean-spread test for BTC/JPY and BTC/ZAR. The first panel (columns 3 to 7) displays the results for BTC/AUD, while the second panel (columns 8 to 12) is for BTC/EUR.
The results of the test equation for BTC/JPY (column 6) and BTC/ZAR (column 11) provide convincing evidence to reject the null hypothesis (H2) that the buy–sell spread of MA signals are not different from zero and we conclude that they are different. This provides evidence to submit that TA methods may be employed profitably in BTC/JPY and BTC/ZAR. As in Table 6, the regression analysis was generated with robust standard errors and subjected to similar validation procedures.
So far, the study has examined the profitability of TTRs under a dynamic CAPM model that accounts for market risk using CAPM-based equilibrium returns. The results show that a time-varying risk premium can explain profits. When comparing the mean returns between the equilibrium model and actual series, the study finds that after accounting for risk, the previously discovered profits using the actual series diminish, implying that the Bitcoin market has elements of time-varying risk premium. After accounting for risk, TA has been found profitable in BTC/AUD and BTCJPY, but such profits diminish when studying BTC/EUR and are completely gone in BTC/ZAR.
6.3 Robust and completeness test
Tables 8 and 9 present the results on the momentum effect being tested for the third study hypothesis [H3]. The hypothesis examines whether price changes (or returns) have an association with TA signals of buy and sell trades as per Eqn (9).
Observation of the results for each of the regression outputs reported in Table 8 under both buy and sell signals provides strong evidence that there is an association between price changes of BTC/AUD and BTC/EUR, and the TA trade signals. This means that the null of H3 is rejected. The test serves to examine whether the properties of a trend apply to the study. In TA, the primary goal of price analysis (using a chart) is to detect the price trends and/or reversals in their early phases, which trigger trading.
The results of Table 9 provide an answer to H3 in respect of the relationship between price changes (or returns) and MA trade signals specifically for BTC/JPY and BTC/ZAR. The table shows that, like Table 8, there is convincing evidence that there is an association between the returns and trade signals. Overall, the study finds that concerning buy signals, the Bitcoin market possesses a momentum effect across the board as the results are strongly significant at conventional levels.
7. Discussion of results
To address the research question, 4 TA performance strategies were evaluated. To begin with, TTRs were applied to equilibrium returns calculated using the dynamic CAPM model. Second, the TA results were then replicated using the actual return series for comparison and robustness purposes. Thirdly, the study examined the extent to which time-varying risk premiums affect performance to determine the profitability of TA. Finally, the momentum effect in TA was investigated as a possible secondary mechanism to corroborate the results. The study's findings are similar to those of Gerritsen et al. (2020) and Grobys et al. (2020), who found that TTRs are more cost-effective than the buy–hold strategy when dealing with Bitcoin daily data. Their study investigates TA using trend-following tactics like the simple moving average. Further support is given by Tiwari et al. (2018) and Resta et al. (2020), who also emphasise the importance of TA and conclude that TA returns surpass those of a buy–hold strategy. Overall, the study finds that the performance of the chosen TTR strategies is superior to the buy–hold strategy. The study is different in that it accounts for time-varying risk premiums and finds that some of the registered profits diminish after the factoring of risk. Bitcoin may be seen as a natural laboratory for using TA because it has no apparent fundamentals to investigate. The study offers evidence that the MA trading rule can predict Bitcoin returns even after accounting for time-varying risk premiums. Similar to known literature (Ülkü and Prodan, 2013), the profits found in Bitcoin exchange rates are found to diminish after accounting for time-varying risk premiums. In the evaluation of the momentum effect, the study finds similar evidence to that of Borgards (2021), in that the Bitcoin market possesses a momentum effect. Emerging markets are known to be less liquid than industrialised markets and have more concentrated trade. As a result, it is only natural to assume that inefficiencies could be more easily exploited in these markets. Gerritsen et al. (2021), however, find that the informational efficiency of Bitcoin has improved.
8. Conclusion
The paper examines the profitability of 24 TTRs in each of four Bitcoin exchange rates (BTC/AUD, BTC/EUR, BTC/JPY and BTC/ZAR). The results show that the chosen FMA TTRs are all successful in generating profitable signals for Bitcoin returns. The buy signals generate positive returns and sell signals generate negative returns, which are, on average, significantly different from the returns earned by the buy–hold strategy. The study results are consistent with Grobys et al. (2020) and Borgards and Czudaj (2021) who found that the trading rules are successful in predicting Bitcoin price movements. The study also observes that the Bitcoin market may possess a momentum effect. Though these results suggest market inefficiency, we find that time-varying risk premiums can diminish profits and thus moderate the potential of TA as an analytical tool in the cryptocurrency market.

Note(s): The first column is the tabulation of moving averages rules. Column 2 is the technical trading rule (TTR) structure. For reporting purpose, the table is divided into two panels. The first panel (columns 3 to 6) displays the results for BTC/AUD and the second panel (columns 8 to 12) gives results for BTC/EUR. Each row (1–24) presents a regression output for Eqn (8). Column 3 is the coefficient (α_1) of X_(t−1) where the intercept is set to zero. Other regression statistics are reported in the rest of the columns. All the F-stats are statistically significant at 1% level

Note(s): The first column is the tabulation of moving averages rules. Column 2 is the technical trading rule (TTR) structure. For reporting purpose, the table is divided into two panels. The first panel (columns 3 to 6) displays the results for BTC/AUD and the second panel (columns 8 to 12). Gives results for BTC/EUR. Each row (1–24) presents a regression output for Eqn (8). Column 3 is the coefficient (α_1) of X_(t−1) where the intercept is set to zero. Other regression statistics are reported in the rest of the columns. All the F-stats are statistically significant at 1% level

Note(s): The first column shows the list of regression outputs for each technical trading rule (TTR). Then the table is divided into two main panels. The first panel (2–7) reports results for BTC/AUD, while the second panel (8–13) displays results for BTC/EUR. The results for buy and sell signals are reported separately for each exchange rate (BTC/AUD, BTC/EUR). The regression outputs are reported under each long-term stretch for moving average rules, namely, 20, 50, 150 and 200

Note(s): The first column shows the list of regression outputs for each technical trading rule (TTR). Then the table is divided into two main panels. The first panel (2–7) reports results for BTC/AUD, while the second panel (8–13) displays results for BTC/EUR. The results for buy and sell signals are reported separately for each exchange rate (BTC/AUD, BTC/EUR). The regression outputs are reported under each long-term stretch for moving average rules, namely, 20, 50, 150 and 200
Statistical significance: ***1%, **5%, *10
