well i got $x january 23c what can i do with that?

### REPLY:
You can sell $x 23c for any expiration before January, with 0 collateral requirement. It might sound like free money, but beware: if your calls go ITM and you get exercised, you will have to exercise your (more valuable) January calls. So you lose all that time premium. I would only do a calendar spread if you are very confident that the underlying won’t touch the strike before the call (that you sell) expires

### END.
