Doing nothing and wait for the upward move until the price get between your upper strike price and 25 and then tighten your strangle rang buy selling March Put 22.5 and buying March Put 25 to protect your Call gain and now you can turn your tight strangle to double calendar by selling 3 lots call and put to take care of time decay . 2. you can turn outright strangle to double diagonal by selling 3 lots of Dec. 25 call and put so the cost of time decay would be taken care of and wait to see what is the next step market will tell us to take. Stay tune and trade wisely
