Indicators in Strategy Analyzer
Custom indicators when I add them to charts seem to work fine, but when I add them to a strategy using AddChartIndicator and run a back test in the Strategy Analyzer I get errors when I try to access bar information and receive "object reference not set to an instance of an object".
Here is an example:Tags: None

Hi Edge,
That actually didn't work. Not sure what else to try.Last edited by GrumpyTrader; 09-07-2015, 11:32 AM.

After debugging through this it seems the issue is where an indicator calls another indicator from a strategy.
To reproduce the problem:
a) import my example (include an indicator Gt_Vwap and a strategy _Tmp ) The only thing the strategy does is call AddChartIndicator (Gt_Vwap)
b) Run a back test in Strategy Analyzer on _Tmp strategy with the display set to Summary (should run fine)
c) After back test is completed switch to the Chart display in Strategy Analyzer ( you should see a bunch of errors come through the Control Center Log)
To correct the problem:
a) Modify Gt_Vwap indicator to use the Volume[0] object instead of VOL()[0] indicator
b) Solves the errors. Clearly they both should work.Last edited by GrumpyTrader; 09-07-2015, 12:11 PM.

Hello,
I was able to use the provided example to create a test that demonstrates the issue explained in this post. I have submitted this to development for review, If I have any further updates I will post them here.
I look forward to being of further assistance.JesseNinjaTrader Customer Service
