Recent Option Play

I recently sold out of my RVBD $39.00 calls for a 48.07% gain. I was in at $1.55 per call and sold out at $2.50 per call. I made a nice gain but missed out on bigger gains. With last weeks selloff I got a bit spooked and closed out of my position to realize a gain rather than letting the decay eat at my profits. The current bid/ask as I right this is $4.10/$4.30, so I'm happy to realize a small gain, but as you can see quite a bit left on the table.
