Error in backtest

[Libri]

Hi, I have strategy with primary timeframe 1tick (for exact backtest) and secondary one15min (for generating signals). Market replay and live data runs correctly. during backtest it some times calculated correctly too, but mostly it ends with error. I dont know where I can look for a mistake. After initialize it find first signal, but than colapsed.see atttached log and output window.

Hello Libri,

Thank you for your post.

These errors are seen when NinjaScript attempts to access an object that doesn't exist, or when NinjaScript attempts to access an object's properties while that object is null (which means the properties don't exist).

Would you mind sharing the strategy code so we may investigate further? If you prefer, you can send the strategy's .cs file to platformsupport[at]ninjatrader[dot]com with this thread in the subject line: "http://www.ninjatrader.com/support/forum/showthread.php?t=74748"
