Interactive Brokers Combo Leg Limit Order #9287
Description
Expected Behavior
IB brokerage model doesn't allow combo leg limit order with 4 legs.
From IB API Team
For combination orders that contain two legs, you can set a price per leg, and the order must be set to NonGuaranteed.
For combination orders that contain four legs, you cannot set a price per leg. The limit price must be set on the overall order object. You must not set the order to be NonGuaranteed.
So, in the case of the client example below, this was a four-leg order with a price per leg. This is not allowed.
Actual Behavior
No restriction. Users are placing orders in backtest that are not allowed in live mode.
Potential Solution
Cannot submit with more than 4 legs.
