unhandled exception trapped - unknown reason

[liorsham]

Hi,
I'm getting unhandled exception (in pop-up window, after trying to run a strategy on a chart), but I couldn't find where it's thrown (using visual studio). my strategy is using custom indicator (but I don't see it's being called at all).

This is what the trace file generated:

Hello liorsham,

Thank you for writing in. If this issue only occurs when you are running the custom strategy, please export your custom strategy following the instructions in this help guide document: http://ninjatrader.com/support/helpG...ightsub=export

Thank you in advance.

Hi,
no need, problem solved - there was a call to Times[0][-1], which is working in NT7 but causes segmentation fault in NT8.
fyi. thanks.
