If your strategy has a bias of 100, it never takes short positions. Imagine a strategy based on a flip of a coin: "heads" - go long, "tails" - stay out of the market. This position will have a bias of 100 and will appear quite profitable if backtested in a rising market.

Added a new performance metric, called "Bias". It's calculated as > 100 * (L - S) / (L + S), where L is the number of long trades, and S > is the number of short trades. can you explain a bit more on the usage of bias? is it the ratio of long trades to short trades? shall it show how "balanced" a strategy is? -- You received this message because you are subscribed to the Google Groups "JBookTrader" group.
