You put on a calendar spread with the stock at 27.50, the IV is 55. Sell the March 30 call for .90 and buy the April 30 for 1.35. By March expiration the stock is 28.50 and the IV has fallen to 35. You captured all the March premium, however your April 30 is less than .90. What could have/or can now be done to salvage the trade?
