What are the margin requirements for futures?

We use industry-standard SPAN margins.

We do not support intraday margins*.

*Intraday margins are a reduced margin requirement, sometimes allowed by brokers. Just because C2 doesn't allow their use in a C2 Model Account does not mean AutoTraders cannot take advantage of them. Their brokers will obviously apply the most favorable margins available. C2's requirements are inherently conservative, by design.
