Fat Tails: There is a bug in lines 89 to 95, as you have initialized the same DataSeries twice and not initialized another one. Big DUH on my part, thank you for pointing that out. Fat Tails: Further, I do not understand, why you use plArray, phArray and indArray. You can access Low, High and smis in the same way, no need to create new objects with identical values. Good point, but I'm going to keep the indArray for portability. Now as I edge closer to the solution when I add the necessary commands to make the arrays work properly, the editor comes up with numerous errors on the Data Series syntax that weren't problems before. Can you please help me figure out why this is happening, and how to fix it? TIA

If you post a screenshot of the errors then I do not need to install that stuff on my side.

That looks like a bracket problem. For OnBarUpdate(), you open the first bracket in line 120. This bracket is closed in line 191. This marks the end of OnBarUpdate().

The question now is what to do with the abandoned code in line 194 and thereafter. You cannot set any values outside OnBarUpdate().
