OnStartUp event doesn't always finish before OnBarUpdate

[adamus]

I'm seeing a recurrence of my OnStartUp code not completing before Ninja fires the OnBarUpdate.

Are there any circumstances that are known to cause this that I should be aware of?

Thanks

Hi Adamus,

Thank you for the post.

This should not be possible as the OnStartUp() is called before the OnBarUpdate() and will finish the logic inside the method before the other methods get called.

What are you seeing with the script?
Have you tried using Print Statements to confirm what you are seeing?

Its because I'm using Print statements that I know Ninja is doing this.

This is only the third time it's happened in about a year but it definitively 'happened', which is why I have code in place to catch it when it does.

I am using GetBars() in the OnStartUp event - synchronously I hasten to add - so this is probably the root of the problem.

However I detect the situation quite simply - I set a flag to true as the last line of code in the OnStartUp event and I check that the flag is true before allowing the OnBarUpdate code to execute.

While trying to isolate the cause of the issue today, the situation returned to normal and I can't get any further evidence for it now - unless it does it again tomorrow.

Adamus,

Would you be willing to send me your script to support[at]ninjatrader[dot]com so that I may test out the code on my end as well?
