Error when Enable Strategy

[simple_goodoboy]

Hello,

If I remove "myEntryLongOrder != null && " from the if statement in the attachment and try to enable the strategy, I get the error in the attachment below.

Is there any reason why I would get this error?

Thanks,

Hello simple_goodoboy,
Thank you for your post.
Since this conditional checks if myEntryOrder is null or not, when you take this out, the IF statement evaluates to true and the CancelOrder method attempts to reference a null object. If the IF statement above this does not evaluate to true, your myEntryOrder will never be set to a value.
If there is anything else I may assist with please let me know.
