Evidence Based Technical Analysis

In fact, I think risk management is much more important than prediction in building a successful strategy. His interest in technical analysis dates back to the late 50’s when as a teenager he began studying the works of Edwards & Magee and the point & figure charting method developed by Abraham Cohen of Chartcraft.

Filled with in-depth insights and practical advice, Evidence-Based Technical Analysis provides you with comprehensive coverage of this new methodology, which is specifically designed for evaluating the performance of rules/signals that are discovered by data mining. Experimental results presented in the book will show you that data mining–a process in which many rules are back-tested and the best performing rules are selected–is an effective procedure for discovering useful rules/signals.

For too long TA practitioners have used overly vague terminology and methods for predicting the market. Presumably many thousands of investors have tried to put these into effect losing themselves money and causing heartache in the process. A representative portfolio that began in 1984 has earned a compounded annual return of 23.7%.

Using different trading strategies, a significant paper profit can be achieved by purchasing the indexed stocks in the respective proportions. The results show that the neural network model can get better returns compared with conventional ARIMA models. The experiment also shows that useful predictions can be made without the use of extensive market data or knowledge.

This paper presents a study of artificial neural nets for use in stock index forecasting. The data from a major emerging market, Kuala Lumpur Stock Exchange, are applied as a case study. Based on the rescaled range analysis, a backpropagation neural network is used to capture the relationship between the technical indicators and the levels evidence-based technical analysis of the index in the market under study over time. Many investors claim that they experience positive returns, but academic appraisals often find that it has little predictive power. Of 95 modern studies, 56 concluded that technical analysis had positive results, although data-snooping bias and other problems make the analysis difficult.

As an approach to research, technical analysis has suffered because it is a “discipline” practiced without discipline. The aim of the whole backtest is to find out whether any of the tested rules offer returns better than zero (or those obtained using random entry/exit signals) with a statistical significance level of 0.05. Methods vary greatly, and different technical analysts can sometimes make contradictory predictions from the same data. The main point of the book is the supremacy of what the author calls objective technical analysis over subjective technical analysis. I would also like to make clear the fact that this is not a book about testing trading systems but about testing trading signals. The others being things more related to risk management duties like position sizing, diversification, and determining stop loss levels.

While working as a broker for Merrill Lynch between 1973 and 1977, Aronson wrote several internal technical analysis memos including one in December of 1973 to Robert Farrell, Merrill’s head technician. It predicted the extent and duration of the 1974 decline and the timing of its reversal. During this time Aronson was in regular communication with James Hurst, a pioneer in the application of cycles to market data. Data scientist deal with eur this problem by splitting their data into training and testing sets, then using bootstrapping techniques and ensemble methods to optimize their models on the training set, and finally testing their models on the out-of-sample or testing set. If the model does well on the out-of-sample test, you can say you are in the presence of a good model. You will never hear any of these words in any of the trading books you normally come across.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon.

About The Author

If you want to use technical analysis to navigate today’s markets, you must first abandon the subjective, interpretive methods traditionally associated with this discipline, and embrace an approach that is scientifically and statistically valid. David Aronson, author of “Evidence Based Technical Analysis” (John Wiley & Son’s 2006) is adjunct professor of finance at the Zicklin School of Business where he has taught a graduate level course in technical analysis and data mining since 2002. Because the case study aims to select the best trading strategy of several thousands, it is clearly a data mining endeavor and thus prone to data mining bias. The author uses improved White’s Reality Check andMonte-Carlo permutation methods to mitigate the effects of the data mining on the obtained performance results. As an approach to research, technical analysis has suffered because it is a “discipline” practiced without discipline. In order for technical analysis to deliver useful knowledge that can be applied to trading, it must evolve into a rigorous observational science.

Likewise, complete information is reflected in the price because all market participants bring their own individual, but incomplete, knowledge together in the market. There’s a lot of useful material in this book – there’s also a lot of pseudo scientific bigotry. The scientific method is held up as the Holy Grail and without doubt it has it’s uses – but it’s only part of the story. Once you’ve hit upon some innovative idea then the scientific method is merely a process of shaping it up. Half the book can be dismissed as the author attempting to constrain the world within the scientific method – the rest of the book is very useful – particularly for avoiding the hunt for fool’s gold.

Evidence Based Technical Analysis : Summary

In 1990 AdvoCom advised Tudor Investment Corporation on their public multi-advisor fund. As an individual investor, I would not recommend this book to any individual investor. Just like I would not recommend any other trading or investing book that claims to predict future prices. You don’t need any of that when you know that the US equity market goes up in the long run and that all individual stocks are highly correlated to the market. In particular, he wanted to put under scrutiny many of those technical analysis rules that have for so long been deemed as “predictive”. He does not do exactly what I described above because he uses something called MonteCarlo Permutation Method. This compares favorably to the ARR for the buy and hold strategy (11.05%) and to the best results obtained using the system with no technical analysis knowledge embedded (13.35% with 126 trades).

If you want to use technical analysis to navigate today’s markets, you must first abandon the subjective, interpretive methods traditionally associated with this discipline, and embrace an approach that is scientifically and statistically valid. Grounded in objective observation and statistical inference, EBTA is the approach to technical analysis you need to succeed in your trading endeavors.

Nonlinear prediction using neural networks occasionally produces statistically significant prediction results. However, many technical analysts reach outside pure technical analysis, combining other market forecast eur methods with their technical work. One advocate for this approach is John Bollinger, who coined the term rational analysis in the middle 1980s for the intersection of technical analysis and fundamental analysis.

The paper, however, also discusses the problems associated with technical forecasting using neural networks, such as the choice of “time frames” and the “recency” problems. Over the past two decades, numerous articles in respected academic journals have approached technical analysis in a scientifically rigorous and intellectually honest manner, and now,traderlooks to continue down this path.

Experiments were performed on a major Italian stock market index, also taking into account trading commissions. The results point to the good forecasting capability of the proposed approach, which allowed outperforming the well known buy-and-hold strategy, as well as predictions obtained using recurrent neural networks.

Experimental results presented in the book will show you that data mining—a process in which many rules are back-tested and the best performing rules are selected—is an effective procedure for discovering useful rules/signals. However, since the historical performance of the rules/signals discovered by data mining are upwardly biased, new statistical tests are required to make reasonable inferences about future profitability. Two such tests, one of which has never been discussed anywhere heretofore, are described and illustrated.
