Dear Quantshare,

as I am using quite complex custom indicators, my screens take quite a long time to calculate. I then found out, that by modifying my indicator I can get a massive speedup: In the indicator, instead of calculating the values for the whole "result-array", I just calculate the value for the current bar (same as the bar that my screener is looking at).

To be able to screen at past bars, I calcultate the current bars difference from the total of bars. This number is then transfered from the screener to the indicator as a static parameter.

currentbar = TotalBars() - Count() - 1;
AddColumn('CurrentBar', currentbar); // Screening on a past date, currentbar returns 30 in the screener
AddColumn('myIndicator', myIndicator(30)); // Indicator is just calculating result[cFunctions.Close.Length - 30]

So far so good. Now I want to use this method in the simulator. So I need to change my static indicator-parameter to a dynamic one, containing the date or bar number the simulator is currently looking at. Is this possible?

The simulator does not run the indicator once per bar. It calculates it once and then use the result to generate signals.
So this screening optimization would not work with the simulator since all indicators bar values are needed by the simuator.
