NinjaScript Output Disappearing After Running Strategy Analyzer

[vossom]

Hello,

I am testing a strategy using Strategy Analyzer and I have a number of print statements included. After Strategy Analyzer completes, sometimes very quickly, the NinjaScript Output window is automatically cleared.

Is there any way to stop this from happening or somewhere I can find the Output for the Strategy execution?

Thank you!

Hello vossom,

Somewhere there may be a script calling ClearOutputWindow() likely somewhere in OnStateChange().

It might be another script and not this script.

If you have visual studio installed, you can click the Visual Studio icon on the NinjaScript Editor to launch, and then Ctrl + f to find, and 'Look in' set to 'Current project', searching for ClearOutputWindow, and click Find All. This will list all scripts calling ClearOutputWindow() to help you find the script causing the behavior.

Hello,

Nowhere in my strategy is this method called. The only indicators that are used within the strategy are EMA and ATR. I have checked the code for both and neither of these contain this method either.

The same thing also occurs when reloading a strategy.

Also if I have an issue with a Strategy and Strategy Analyzer can't run it, the same things happens there as well and I am unable to see the script error message.

Any other ideas?

Thank you

Hello vossom,

I'm telling you it could be any script.

All scripts will run OnStateChange() when opening the Strategies or Indicators window, not just the script you are working on.

May I confirm you have check every single script in NinjaTrader?

A script that cannot run in the Strategy Analyzer either has an error appearing on the Log tab of the Control Center, doesn't have any data on the Chart, or isn't placing orders due to the logic.

Hi Chelsea,

The output is clearing after running a backtest when Strategy Analyzer is already loaded.

Are you telling me that every single script is executed (initialized) every time I click Run on Strategy Analyzer?

Thanks,

Hello Vossom,

All strategies have an instance created and OnStateChange() run after a backtest, when loading the Strategy Analyzer, etc, because this is used to populate the Strategy drop-down.

Please confirm you have checked every indicator and every strategy for ClearOutputWindow().

Thanks for confirming. I did find some other strategies that have this method, so I will clear those out.
