First revision: September 20, 2017. A section on pitfalls of validation tests was added.

It was about time that someone spoke up about the perils of chart analysis, back-testing and data-mining clearly and honestly. In this book you will learn why naive chartists and quants have no chance of profiting from trading the markets and how expert chartists and quants attempt to maximize their winning odds. There are many examples that illustrate the points made in the book.

You will learn why:

  • Classical chart patterns are unprofitable
  • Chart analysis has no logical foundation
  • Statistical hypothesis testing is not applicable in system development
  • Naive quants are fooled by the expectation formula
  • Out-of-sample validation tests should be avoided
  • Walk forward optimization and Monte Carlo analysis are ineffective
  • Frequent backtesting almost always leads to failure

You will also learn about: 

  • The limitations of backtesting and how to properly use it
  • Data-mining and data snooping bias
  • Processes that contribute to data-mining bias
  • Popular myths about data-mining bias
  • The pitfalls of strategy validation tests
  • Effective trading system validation tests
  • Determining capital requirements for system trading
  • Practical ways to determine position size
  • The current alternatives to technical analysis
  • Cognitive biases that plague chart analysis
  • The proper use of patterns and indicators by expert chartists
  • The effects of trading friction and trading timeframes on profitability

and much more.
