This leads to less reliable backtests and thus a trickier evaluation of a chosen strategy. Distribution of the net profit of 2000 randomly generated trading strategies for the E-mini S P 500 futures (daily bars, 13 years, trading costs of 15 per trade). Results from Roll Yield Optimisation, i therefore generated a composite, Roll Yield-only equity curve (by removing from the improved strategy equity curve the returns that could be attributed to the Trend Following component). M script contains the following code: Script to call the ESbootstrap function out optimize(ESbootstrap hist(arpe) title(Histogram of Trading Strategy Sharpe Ratios) Enter run ESbootstrapCaller at the Matlab command line, and we obtain a histogram something like this: Antony Jackson, CFA London Quant Club 16/.

Backtesting trading strategies necessarily involves a very limited amount of historical data. For example, I seldom test strategies with data older. Backtesting is a key component of effective trading-system develop ment.
