About the Author
Keith Fitschen has been developing technical trading systems for the futures markets for 20 years, actively trading his systems. His initial research was on the quantification of curve-fitting in system development and resulted in a methodology that relates the degree of overfitting to the number of trades in the development sample. With this method he developed the mechanical system Aberration. Developed in 1986, it was commercially released in 1993 and has been feted as one of the top 10 trading systems by Futures Truth. Fitschen also developed the Start-Trade Drawdown criteria, which is a better measure of risk to a small-account trader than traditional drawdown metrics.
Fitschen, who has a master’s degree in electrical engineering (with an emphasis on stochastic estimation), has developed guidance systems for tactical air-launched weapons and acoustic tracking systems. This expertise in noisy time series data has led to his success in developing trading systems for noisy market data.
