Any good brokers for portfolio margin other than TD Ameritrade and interactive brokers?
If they support API based trading it would be better but it's not required.
Hi,
What sectors has liquid options? Tech sector has NDX and QQQ which have decent options liquidity.
What other sectors have good options trading volume so that fills can be good?
I am using TD ameritrade with portfolio margin and use their API.
I was thinking of moving to IB as the margins from TDA was higher than IB.
But in IB there is a 30% margin rule for concentrated positions. Do you know what that means?
It looks like there is a huge IV crush for the past 3 days for SPX Calls. Is that because of low volume? Never seen so much crush so quickly for an index.
