However, this alert never happens. Why?

[NinjaTrader_Bertrand]

Welcome to our forums here - Alerts would only trigger in realtime so this would be never called.

Please move the Alert part to your OnBarUpdate() and then retry.

What other things can I do in the OnStartUp method?

Hi,

Thanks for your reply,

Just wondering. What tasks are available in the OnStartUp method. Can I do inital data collection on the historical bars?

[NinjaTrader_Bertrand]

You could allocate custom resources needed that would benefit from being called only one time after the script's Initialize() - http://www.ninjatrader.com/support/h.../onstartup.htm

Hi & thanks for your help.

Funny enough, I've tried the Print function, but this will also not work. This caused me concerns if the OnStartUp() gets executed at all. So I've tried showing a message box from within this method and it showed up. Can someone please explain to me why the Alert() and Print() functions will not work in OnStartUp?

[NinjaTrader_Bertrand]

The alert will not work in backtesting, this is expected - what call were you using in OnStartUp() for the other checks - would you have a snippet?

Is this on latest Beta 18?

[Avrohom]

Hi, Thanks.

Well I'm still working on it. Basically, I want to check current trend direction and size, before leaving control to OnBarUpdate() method.

At current I'm using beta 17.

Avrohom, there are no bars available for the strategy to check in the OnStartUp() method. The first instance of when a bar would be available is in OnBarUpdate() when CurrentBar == 0.
