Hi guys, I just have a question regarding option pricing. i recently sold(on my demo account): Short SPY weekly OTM put option, expiration 7th of June, at strike 160.00, premium received 0.18, and quantity 10 contracts. by equation this should amount to : 10contracts * 100 shares per contract * premium 0.18 = 180$ profit if price is above 160.00 on the day of the expiration the Bid/Ask of the option was 0.00/0.01, yet the profit i could take if i close the option immediately was only 17$, instead of the 180$ calculated if i waited for the option to expire. i know this is a completely newbie question but i can't seem to figure it out or find online why the pricing is this way. i don't understand why, if i close 10contracts by the difference of 0.17(0.18 - Ask0.01=0.17), i only receive 17$ instead of 170$. if someone could explain this to me i would be very grateful because i can't seem to find an answer online. thank you for the answers in advance!
