I didn't know you could do that. Are you saying that one can have an account with one broker and trade through another broker? How does this work? I never heard of such a thing.
Quote from 50 cent:
nothing could be further from the truth. the broker needs to answer to the exchange's margin requirements, however it can require its clients to have any margin that the broker chooses, either lower or higher than the exchange's requirements. IB's margin requirements are lower than the exchange's requirements. Global Futures for example, require margin as low as $300 per contract for ES/NQ/YM. theoretically each broker can require different margins and can choose different times of the day for switching to overnight margin. you just have to shop around.
Quote from 50 cent:
that's correct, broker takes responsibility for the rest of the margin. you have brokers offering $300 and $500 margins, way below exchange requirements.
The way I understand it is this - the reporting for margin compliance is based on the position of the accounts at the market close. So technically, only at the market close does your broker need to "show" the exchange that the customer has the correct margin to hold the position.

$300-$500 on OVERNIGHT margins? I've never heard of that. I realize daytrading margins are like that, but the original question was about overnight margins.
