Topic: Different results with exact same system & data
I'm new to the strategy builder, but I've encountered something odd. I built a strategy using the data provided by FSB and saved it. I then built the exact same strategy with all the same parameters using the same currency pair and time frame and again using the exact same data provided by FSB. In other words, everything was exactly the same. However, the back test results were off by a good 20%.
I understand differences in results when using data from different providers, and understand getting different results when using a strategy live. But how can the results be different if I back test identical systems on the exact same data?
