We are going into the final hours before the expiration. This is the time when the volume and volatility can go up because lots of traders exit there positions before the weekend (expecialy when the short-squeeze threats are made). Since this was a naked call I feel that is reasonable to make a move now. I am exiting by paying 2,50USD/stock for buying call options at strike 300. This results in a net profit of 15USD/stock.
If you would invest 10 000 USD into this trade. You would end up with 576USD profit. Trade lasted for less than 72 hours.
