Compiling Question

New comment
 

I have several indicators, that I have to keep compiling, to keep the items displayed on the chart current.  Below is some code to show what I mean.  When the platform is launched or when the indicator is added to the chart, there is no problems.  When period "0" becomes period "1", the lines stop drawing, until I recompile the code.  Is there a command or routine that I need to use to get the lines to keep drawing, even when the period changes?


Thanks, again!

Thanks, again!

This line uses "EndTime", which is only updated when "TimeHour(Time[i]) == Hour_Num && TimeMinute(Time[i]) == Minute_Num":

ObjectSet("5mg_Line"+h,OBJ_TREND,EndTime);

So you'll have to modify your time checks to get EndTime modified.

Also, consider changing your i to:

    int i = MathMin(Bars-1,Bars-Counted_bars); // i will range from 0 to Bars-1.

Otherwise your "if (i>0)" condition will not execute beyond the first run.
