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 naïve chartists and quants have no chance of profiting from trading the markets and how expert chartists and quants attempt to maximize their winning odds. Many examples illustrate the points made in the book.

You will learn why:

  • Classical chart patterns are mostly unprofitable.
  • Chart analysis has a shaky logical foundation.
  • Statistical hypothesis testing is not applicable in system development.
  • The expectation formula deceives naïve quants.
  • Out-of-sample validation tests should be avoided.
  • Walk-forward optimization and Monte Carlo analysis are ineffective.
  • Frequent backtesting almost always leads to failure.
  • Most intraday traders fail, and many get ruined.
  • Experienced chart traders do not use patterns for market timing. 
  • Focusing on invalidating strategies is important.


You will also learn about:

  • The limitations of backtesting and its proper use
  • 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 and position size for system trading
  • The current alternatives to technical analysis
  • Cognitive biases that plague chart analysis
  • The effects of trading friction and trading timeframes on profitability



and much more.
