OCO Bracket orders in Sierra Chart

I have very recently switched to CQG from CTS via a partner FCM, and trading via CQG FIX with Sierra Chart as a Front End.

Yesterday I received a partial fill due to a margin violation, yet the previous day an identical order went thru without issue. I never experienced this issue via CTS FIX. Sierra Chart Support suggest the difference must be within CQG FIX.

I'm using the OCO bracket function on Sierra Chart - I'm submitting an order to buy 3, and two orders to sell 3. (on stop and on profit taking limit) Could it possibly be considering a "worst case" position of -6 (until fill confirmation for +3 received) If so this is forcing me to use double intraday margin to initiate trades.

This does not though answer why Monday's trade went thru without issue.

On CTS the order to buy 3 was sent, and on fill confirmation (+3) the two sell orders (limit and stop) were sent giving a worst case position of -3 which isn't breaching limits.

I have the FIX Log from yesterdays issue if required.

Please could you advise of any possible causes and if a CQG FIX update is feasible to solve the problem.

Thanks.
