OCO order different contracts

[habibalex]

When I have OCO set, it is closing orders in different instruments, how do i do oco only for a single instrument

Hello habibalex,

Thank you for writing in.

Are you leaving the OCO function on between placing order pairs? This is the only reason I can think of for the behavior that you describe. It is necessary to shut the OCO function off in between, otherwise it will give all of your OCO orders the same OCO ID and cause order submission to work unexpectedly.

I look forward to your response.
