On the other hand, some developers may optimize their strategies over a historical data set (i. , run it multiple times over the past three months of EURUSD tick data) on purpose – which can lead close all trades ea mt4 to curve-fitted results. While there can be some benefits to ea bbma optimizing a strategy over historical data, results of a curve-fitted strategy can be misleading as only the best trades are cherry-picked, and the results of forward-testing the same strategy can triple ma crossover ea be significantly different.
