Hi ! Suppose a stock is trading at Rs 100 and I short Rs 150 call option. At expiry stock ends at Rs 110, but I am not able to square off my position due to non availability of buyer. Will I make any profit?
You are short 150 CE. So you make full gain of all premium that you have received.
It is a hypothetical question. You will never find any stock with OTM call whose strike price is 50% above ATM.
And for other extreme available OTM calls, there will be very less liquidity to no liquidity.
