Hi guys,

has anybody managed to setup Sierra to trade futures spreads via IBKR (TWS)? Supposedly this requires some special symbol which is beyond me.

I am using Denali for data, but would like to send trade orders via IBKR for the spreads.

Any ideas would be appreciated!

Anybody? Is this even possible?

To Sierra guys:

The issue is that Interactive Brokers does not expect via its API to receive a symbol for a spread, i.e. LEG1-LEG2, but they expect you to use their API to create a Bag, get an contId for each leg, place it into the Bag/Combo and send it like that to their API.

Is it possible that you implement that?
