Just for the record, in my portfolio-margin account the margin on selling 30 such puts shows as $1200: I also checked qty 3000 and the req margin shows at $123,800, which matches the above.
Im going to check later.I was trading MSFT a while back and putting on OTM verticals and calendars for credits.I was hit with a surprisingly high margin and told there was some minimum charge despite no risk..
the min like 25 dollars per contract (transaction allowance) https://www.theocc.com/Risk-Management/Risk-Based-Haircuts I bet a prime broker will do you better though if you have access to that.
Perhaps it's the Hindendberg report team loading up on long OTM puts for the long term demise of TSLA. Lol.
