Strategy Analyzer Platform Crash

[GrumpyTrader]

Running a backtest in the Strategy Analyzer with the End Date set to the current date will some times cause a crash of the platform.

Here is the relevant trace log entry:

Hello GrumpyTrader,

100 trials using the Sample MA Crossover strategy with the Standard optimization type and invented historical data for the selected date, failed to produce the error. May I ask you to provide in an e-mail to platformsupport [at] ninjatrader [dot] com, a screenshot of your Strategy Analyzer settings, as well as an export of the historical data you are testing against, and the strategy you are using?
