Post From: OCO trade activity log question

Not sure about this.

We tried to cancel both orders in an OCO group and got this:
Order cancellation failed | Order Cancel Reject. Text: Order already in pending cancel or pending replace state. Internal Order ID: 16306. Service Order ID: 203661757. Symbol: ESM6 | 2016-04-27 04:06:04 *

This message is expected and is really hard to avoid.

It is harmless. The problem is both OCO working orders are getting canceled but the server is also canceling the other side of the OCO which causes this message.
