let's say that 1 stock of XYZ currently is 50$.
I bought leap call option for XYZ with strike price 50$ and premium 10$. When exp date will come and I will exercise my call option. How much will I pay for single stock, if XYZ current price is already 100$?
Current price-strike price-premium. 100-50-10=40$
or
Current Price-premium? 100-50=40$?
