I think you may have an error in your margin calculation. These are oX margin guidelines for naked puts and calls:Quote from hajimow:
It might be opened for $0.10 but the natural price is only $0.05 less $0.025 in commissions at oX, with a margin requirement of $560 per contract. This means about 0.5% return on margin.
Disclosure: I will not do the trade that I mentioned because I am already loaded. If I could do the trade, I would not change my credit from 0.1 to 0.05 to make the order a market order. I will pay 1.5 for commission so credit will be $8.5 per contract.
I have to have (20% 29.5 - 2.5)x100=$340 per contract.
So the profit will be $8.5/$340 x100=2.5% in 5 weeks.
If the market goes down and the stock dips, you can get more than 10 cents from the spread.
My broker is IB.
Another disclosure: No trade is safe. We just believe they are safe and profitable. Once we enter the trade, time might prove we were very wrong.
"25% of the underlying market price + the premium - amount out of the money OR
10% of the underlying market price (or strike price for O-T-M puts) + the premium, whichever is greater."
Even considering your fills, I guess your -2.5 should be -0.25?
oX trade calculator gave me $560 margin for the current quotes.
