I am going to suggest you go ahead and book the profit on the MSFT debit spread.
MSFT is trading around $212.73 as I write this. And by closing the position today, the gain will be about 40% for 4 days.
Here is how you close the position:
Sell to Close October 16th - $207.50 Call for $8.20
Buy to Close October 16th - $212.50 Call for $5.00
The net credit will be $3.20 per spread. The debit when the trade was initiated was $2.30 per spread.
If you traded the suggested 6 lot, the cash return will be $.90 per spread or $540 for the 6 lot.
This works out to a gain of 40% for 4 days.
