I just learned that with my IB account it is $3486 to open a NQ trade and $2789 for the ES ?????
This is much higher than my Futures account I have (approx $500 or so)... and AMP and others...
Why is IB so high?
Even worse Intraday Initial Margin for RTY and EMD at IB:
RTY: $4,511
EMD: $11,475
RTY now has 4x volume of TF which it is replacing, yet TF has 50% lower intraday margin at IB.
Ive been trying to get IB to introduce intraday margin on RTY for months now but they just ignore me.
But to answer your question, at least for products like ES and NQ, IB seem to set overnight maintenance margin at 20:1 leverage. And intraday maintenance margin at 40:1.
eg if a contract has notional value of $100,000, IB seem to want $5000 overnight maintenance margin (20:1) and $2500 intra day (40:1)
Initial margin is a bit more than maintenance margin.
Overnight margin on the DAX and ESTX50 futures are even worse at IB, about 10% of the notional or 10:1 leverage.
I think IB now has 125 billion in client funds, so they are being extra conservative with how much leverage they give clients.
