Error on plotting indicator ... Index was outside the bounds of the array

[Richard168]

I modified the NinjaTrader supplied Pivots Indicator by changing R3 and S3 to M1 and M2. It compiled and plotted fine. However, after I added M3 and M4, it compiled but does not plot. It's strange that it will plot 7 pivot lines, but not 8 or 9 pivot lines.

The error message is: "Error on plotting indicator 'RichardPivotsTest'. Please check the 'OnBarUpdate' or the 'Plot' method: Index was outside the bounds of the array."

I checked the forum. One suggestion is to add:
If (CurrentBar < 1) { return; }

I tried that but to no avail.

I have seen this type of problems before, I managed to fix some by hit and miss. However, I can't find any good documentation to help me understand and address this type of porblems once and for all.

Can anyone suggest a possible solution or what is the cause of this problem!

Many thanks,

Richard

The Pivots Indicator uses a custom Plot. You need to specify the brushes for any extra plots.
