I actually didn't conceptualize it as two separate questions, so thanks for explaining it like that.If you are asking about long/short options dollar offsets, that is standard. If you are asking about getting paid for option credit balances, that is not standard.
I'm assuming your answers are correct for Wedbush since that's Lightspeed's clearing firm, right?
If you are correct that long/short options dollar offsets are standard everywhere including IB, then I suppose TheDawn was incorrect when he said the funds are not "available for trading" with IB.
I have read many stories about people using short SPX boxes as a form of margin loan, so this strongly suggests that those funds will also offset long stock positions.
