Hello all, I noticed a difference in the calculation of the moving averages when the custom study is used during system backtests, recalculation and replays. The following code is beeing used: int MAlen;
//MAlen used with 400, 100, 50 sc.SimpleMovAvg(sc.Close, sc.Subgraph[1], MAlen()); float MAVal = sc.Subgraph[1][sc.Index]; These are the results: Backtest: 2876,18188 Difference to Backtest: 0 Recalc: 2876,17627 Difference to Backtest: -0,00561 Replay: 2876,17627 Difference to Backtest: -0,00561 Sometimes the value during replay is the same as during the backtest, sometimes the same as during recalculation and sometimes its completely different. I tried it with various sizes of MALen, the smaller the numbers the higher the difference. Du you know why this is happening and how to prevent this? Thank you in advance. |

This might be the result of a recent optimization done. it is hard to say because there is so much analysis and testing that has to be done. You are only providing an extremely limited amount of information. We will look into this. We want you to test this in the next release to see if it resolves the problem.
