I regularly short options to collect premium. I've never been charged an "exposure fee" by IB. I don't over-leverage myself though.
give me an example of what sort of shorting u do?
i am charged it.. hook line and sinker... i do SPY puts and calls weekly..... for example I am short 100 SPY puts next Friday expiry 227.. this cost me like 12 $ daily.. i think..
one thing i noticed... i dont have to pay if I am SHORT calls.. SPY calls. like 241 stirke for next friday... when u place a trade. now in IB... thick Client. u can see the exposure fee calcualtion the trade will do for u.
