I just exercised a Feb 19 $15 Call (only cost me $400 originally) that i paid for the exercise by selling a Feb 19 $40 Call today for $2k (ended up with $500 extra!).... Still holding onto a March 19 $17.5 Call, trying to come up with $1,750 in the next month to pay for that one as well...took a chance on CCIV calls last week, got lucky on the news. Sell, convert or roll up?
