how to prevent double execution?

[daglas]

Dear friends.
I have very slow execution on IB. When my strategy sent 1 order (for example Long), it needs 3-7 seconds to fill it. But my strategy needs to work on 1-2 seconds time frame.
And often I open 2-3-4 time bigger position then I need. How Can I manage delay until order filled?

Hello,

You can use the OnOrderUpdate method to check the state of the order and prevent the strategy from producing additional trades until the order has been returned as filled or part filled.

We have a reference sample on how to use OnOrderUpdate and OnExeuction to check the state of an order:
