Atomic order operation

[njmeyer713]

Hello-

I am using Rithmic in order to get a funded account with Apex trading.

I am getting an error message that you can see in the attachments.

No idea what they mean. Can I get some help on this please?

Thank you,

Nick

Hello Nick,

This would be a native error coming directly from the brokerage.

The error typically indicates the order is in the process of being changed/filled/cancelled when another action on that order is initiated. An order in the process of a change/fill/cancel cannot be modified until the initial action completes.

Please reach out to your broker to get a full run down of what the error means and what caused this in this particular instance.

Our advice to prevent the error is wait until the initial action completes regarding this order to begin another action.
