OCO with unmanaged orders

[dave1992]

What does the OCO field in SubmitOrder do? Is it just for reference, and you check OCO ids yourself and manage the cancels, or is there something more automatic that happens?

Hi Dave, with this field you can optionally link orders together if they would use the same OCO string.

Thanks Bertrand - you haven't answered my question though. Will anything automatic happen using this field, or is it purely for reference for the strategy code to know which trades to cancel?

[NinjaTrader_Bertrand]

It's a regular OCO order then, if one part of the submitted bracket fills > the other cancels.

Normally all orders in Unmanged are liveUntilCancelled...

[dave1992]

Right, so you're saying that within an unmanaged system, if you fill in two trades to have the same OCO, if one of them fills, the other one will automatically cancel?

You're understanding is correct.
