Price Oscillator Bands for Ninjatrader (works on Some Charts, but Not on Others)

[kh_model 10]

I recently added new plots to an older pre-existing ninjascript that can be found here in post #3 (ElliotOscillator1.2.zip):

My modified version of the above indicator is attached here in this post for reference purposes. In the attached picture, one can identify the two new plots which I added by looking for the yellow colored lines in the subgraph.

 

For testing purposes, I added an input which allows the user to enable or disable the new plots which I added.

 

When the input called "OSC_strengthband_show" is set to false, the code always works and is identical to the older original version from the link above.

 

When the input called "OSC_strengthband_show" is set to true, I have observed that the indicator only works on certain combinations of instrument, resolution, and session but not on others. I suspect that the code is throwing an exception due to a null value or a NaN or something similar which is being generated within the code changes which I added.

 

My lack of deep experience with ninjascript programming should be noted. If anyone here can offer any ideas on how to fix the attached code, it would be greatly appreciated.
