TopStep 'cannot change order' error

[saltminer]

Hi,
a customer of mine is trading with TopStep and NT7, and upon a fill of a short entry and then the placement of stoploss and target orders, an error message comes back about being unable to change the order, and the strategy shuts down.
These are new orders being placed, not being changed. TraceOrders is set true.

See Output Window monitoring text:

**NT** Strategy 'brPriceDiffBreakouts/375cb2e9c87d477a87bb4d469d055fce' submitted an order that generated the following error 'UnableToChangeOrder'. Strategy has sent cancel requests, attempted to close the position and terminated itself.

This strategy works fine in testing. It is live with TopStep that the issue occurs.

Thanks,

Hello saltminer,

Thanks for opening the thread.

It may be worthwhile to view the client's log and trace files for more information on what exactly the strategy did at that time to see receive an "UnableToChangeOrder" error. We could see if the strategy attempted to change an order to a certain level that would be invalid, if the ChangeOrder was submitted and rejected before the previous order was accepted/working, or if there was an in flight execution or partial fill that had made the subsequent ChangeOrder invalid.

If you would like to write in to platformsupport [at] ninjatrader [dot] com with the forum URL and the text "Attention Jim" along with the log and trace files for the occurrence, I will be happy to give you further input on the error received and what can be done to address it.

I look forward to assisting you further.
