I recall getting an email a week ago and deleted. What's the latest policy on GME margin, especially short options? PS: the customer chat is forever unavailable.
Even if you reach someone, they will just say enough to get rid of you. Might as well have no chat support. It's gone completely downhill in the last 5 years.
It seems that all short puts must be 100%-cash-backed assuming assignment, no margin allowed. So it costs $5000 (6000-10*100) to fund a short 60-strike put ($10 price), they should vary the margining based on moneyness.
Same with equities, it's rare to see any margin available. Most are 100% and many are 200% or even 400% margin required.
IBKR used to have a page with a table outlining the limitations on these stocks. Currently that page is empty, its contents has been removed: https://ibkr.info/node/3763 Their FAQ page about this table also states that the limitations have been removed: https://ibkr.info/article/3764
My customer service chat log: ------------------------- Martin Ma: You could check the margin by previewing the orders on trading platform. Then, it would show the change in initial margin requirement.. You could find more information about preview function in the following link: https://ibkr.info/article/644 me: It seems IBKR treats any short puts, at whatever strikes, as if I am buying the underlying GME shares and that I need 100% cash for the purchase without typical regT margin What you are saying is useless Martin Ma: You could check the latest margin requirement me: that's what I am asking you now. this is so useless and waste of time
selling a $50-strike GME put costs as much as a $700-strike Tesla put..and the IBKR CS chat guy said there is nothing put on GME and just check it yourself..
