Chapter 4 provides an overview of statistical analysis as related to TA. In summary, those who state that TA is more art than science deserve the status of astrologers, alchemists and folk healers. A need to simplify complexity and cope with uncertainty makes us prone to seeing and accepting unsound correlations. We tend to overweight vivid eur examples, recent data and inferences from small samples. Detrending the test data set (for example, daily returns for the S&P 500 index) is a consistent approach to benchmarking. ThriftBooks sells millions of used books at the lowest everyday prices.

Evidence-Based Technical Analysis

This book explains how a scientific approach can be used to determine if a technical analysis rule is worth using or not. There is no specific TA rule or approach which is promoted here. Technical analysis is the study of recurring patterns in financial market data with the intent of forecasting future price movements. EBTA rejects all subjective, interpretive methods of Technical Analysis as worse than wrong, because they are untestable. Thus classical chart patterns, Fibonacci based analysis, Elliott Waves and a host of other ill defined methods are rejected by EBTA. Yet there are numerous practitioners who believe strongly that these methods are not only real but effective. Here, EBTA relies on the findings of cognitive psychology to explain how erroneous beliefs arise and thrive despite the lack of valid evidence or even in the face of contrary evidence.

Thus EBTA relies on computerized methods for identifying patterns, and combining evidence into useful trading signals. Due to recent advances in computing and data mining algorithms it becomes possible for the modern technical analyst to amplify their research efforts and find the real gold.

Complex rules can be good simply b/c some strategies require specific market conditions to work.

Even the best TA rules generate highly variable performance across data sets. Our brains are so strongly inclined to find patterns in nature, perhaps as evolutionary compensation for limited processing power, that we often see patterns where none really exist. This tendency toward spurious correlations, evident in subjective chart analysis, is maladapted to modern financial markets. In summary, a rigorously logical method is essential to transform TA from subjective opinion to objective knowledge. I recently took the time to evaluate Aronsons claims/approach and found mixed success on certain markets, and I have become skeptical of the validity of his claims. However, I have yet to come across another who has actually implemented/described the results they obtained, yet many have praised the success of the book.

About David Aronson

He founded Raden Research Group, a firm that was an early adopter of data mining within financial markets. Prior to that, Aronson founded AdvoCom, a firm that specialized in the evaluation of commodity money managers and hedge funds, their performance, and trading methods. For free access to the algorithm for testing data mined rules, go to David Aronson is an adjunct professor at Baruch College, where he teaches a graduate- level course in technical analysis. This book’s central contention is that TA eur must evolve into a rigorous observational science if it is to deliver on its claims and remain relevant. The scientific method is the only rational way to extract useful knowledge from market data and the only rational approach for determining which TA methods have predictive power. Grounded in objective observation and statistical inference (i.e., the scientific method), EBTA charts a course between the magical thinking and gullibility of a true believer and the relentless doubt of a random walker.

  • Two such tests, one of which has never been discussed anywhere heretofore, are described and illustrated.
  • Chapter 4 provides an overview of statistical analysis as related to TA.
  • While they will no longer try to subjectively evaluate complex information patterns, they will need to learn about the kinds of data transformations that produce variables that are most digestible to data mining computers.
  • Yet there are numerous practitioners who believe strongly that these methods are not only real but effective.
  • When done correctly though, using techniques you’ve mentioned above about avoiding bias the AI wasn’t able to learn anything useful.
  • Compute-intensive methods amplify the usefulness of historical data sets.

In other words, EBTA advocates a synergistic partnership between technical analysts and data mining computers to expand the valid base of knowledge called technical analysis. The union of humans and intelligent machines makes sense because the two entities have different but complimentary information processing abilities. Whereas computer intelligence is ill equipped to pose questions and propose variables it has enormous capacities to identify relevant predictors and derive optimal combining functions. The author advocates a more scientific, objective approach to TA, grounded in statistics.

Much of popular or traditional TA stands where medicine stood before it evolved from a faith-based folk art into a practice based on science. Its claims are supported by colorful narratives and carefully chosen anecdotes rather than objective statistical evidence. I took quite some time to read slowly what this section talks about and here are my takeaways. It is important to recognize it is easy to fit a pattern to a time series. However it could be only wishful thinking unless it is tested vigorously with scientific rigor. This is a book which I have been planning to read for quite some time, may be since an an year . Understand how each line of business of a company contributes to performance and how to address division-specific needs.

Compute-intensive methods amplify the usefulness of historical data sets. TA is essentially statistical inference, the extrapolation of historical data to the future. As a recap, Aronson proposes using a scientific, evidence-based approach when evaluating technical analysis indicators. Aronson begins the book by showing how currently, many approach technical analysis in a poor manner, and bashing subjective TA.

I have not tested it, but I agree with the notion that a popular technical analysis is lacking and could be improved upon with a combination of data/computing/statistical methods. When you look at historical data, there is always the problem that it is backward looking – this is a trap that even professionals fall into. Now if you have good test results and you can pin down (e.g., there is a behavioral bias etc.) why the pattern exists Evidence-Based Technical Analysis that is very powerful. Properly executed data mining can locate the best TA rule, but the back tested performance of this rule overstates future returns. Data mining discovers luck as well as validity and, by definition, a lucky streak for a specific rule is unlikely to persist. However, this new approach to technical analysis will require that human technicians abandon some tasks they now do and learn a new set of analytical skills.

Evidence-Based Technical Analysis

Poor out-of-sample performance is evidence of this data mining bias, which is a major contributor to erroneous knowledge in objective TA. 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.

Second, the historical performance statistics produced by such back-testing are then evaluated in a statistically rigorous fashion. In other words, profitable past performance is not taken at face value but rather evaluated in light of the possibility that back-test profits can occur by sheer luck.

If there is a survey it only takes 5 minutes, try any survey which works for you. FinListics presents performance metrics in a way I haven’t seen before. It’s simple to analyze a company historically and against its peers and industry. In summary, the rationalization of financial analysis is still in its infancy. Cognitive biases are important building blocks for the hypotheses of behavioral finance. Support from a sound theory makes luck less likely as the explanation of success for an outperforming TA rule. Building ever more complex and effective rules from simpler rules.

Chapter 2 investigates how biases in our thinking processes, especially with respect to complex and uncertain information, undermines the validity of subjective technical analysis. Chapter 6 explores the value and risk of data mining, the back testing of many TA rules to find the best one. A great contribution of this book is its layman explanation of the data mining problem.

Evidence based technical analysis is dedicated to the proposition that technical analysis should be approached in a scientific manner. First, it is restricted to objective methods that can be simulated on historical data.

While they will no longer try to subjectively evaluate complex information patterns, they will need to learn about the kinds of data transformations that produce variables that are most digestible to data mining computers. They will also need to learn which data mining approaches are most viable and which types of problems are most amenable to data mining. It is important to avoid data snooping bias, an unquantified data mining bias imported from TA rules of other analysts who are vague or silent on the amount of data mining performed in discovering those rules. In summary, data mining presents TA experts with both the opportunity to discover the best rule and the risk of overstating its future returns.

An insidious problem with multiple forms, data mining explains why it is easy to devise a strategy that was a winner in the past, but will fail miserably going forward. There are many software platforms available to backtest strategies and optimize them. However, designing and testing a strategy – and in particular backtesting – requires great rigor and discipline. If you are inclined to believe this, then this book is a must-read. One takeaway for me,is that one has to zero-center the sample for conducting resampling method. This is done to align with the universal null hypothesis of a trading rule –Ho– Returns from the trading rule are 0.
