Order can't be submitted: order status is CancelPending.

[devatechnologies]

Hello,

I need some advice regarding a part of my automated strategy. Here’s the scenario:

• At 7:00 AM, I enter a long trade.
• By 7:05 AM, the trade is in a negative position, but the stop loss hasn’t been triggered.
• At this point, the method ReversePosition() is called. This closes the current ATM strategy and attempts to open a trade in the opposite direction.

However, instead of successfully opening the new position, I encounter an error.

I’ve tried implementing logic to prevent this issue (see code below) but haven’t been able to resolve it. Specifically, I’m looking for:

1. A better way to retrieve the order status after canceling an order.
2. Guidance on how to wait until the order is no longer in the CancelPending state before submitting the new order.

Thank you for your help!

Hello devatechnologies,

Generally you would need to use OnBarUpdate events to poll for changes before doing an action, using a while loop won't let the script properly update and continue. Do you still see this happen if you don't specifically try to create a new order and just call Close on the ATM?

Hello Jesse,

I do have some logic that will just close the trade, and not reverse it, if the position is more than a few points negative. In these cases the ATM strategy will close as expected with no errors.

Actually I think when I was trading 3 contracts there wasn't an issue with closing and reversing the ATM order. Now that I'm trading 5 contracts it seems to happen. What if just called Sleep for a few seconds, giving all the orders(targets and stops) time to cancel?

System.Threading.Thread.Sleep(50); // Pause for 50 milliseconds

Hello devatechnologies,

I would suggest removing the while loop and also do not use Thread.Sleep, those items prevent your script from working correctly. In NinjaScript there should never be a point where you are making the script wait, that prevents the platform from proceeding and changing variables in your script and could cause issues. Do you see problems if you do not do any kind of waiting? You should be polling for changes with each new OnBarUpdate instead of trying to stop the scripts execution.

You're right. I'll get rid of the while loop and not use Thread.Sleep. If I'm going to reverse the position I'll close the ATM strategy, then on my tick data series check to see if the MarketPosition is flat, then when it is enter the reversal order.

Thanks for your help!
