Taking my Profit

The pic below shows a trade I have on: a double butterfly. You can see details of the trade on the pic. There was a long call as part of the trade but I have taken profit on it. The position is showing a profit of almost 10%. The problem is SPX is more difficult to get fills in than RUT and I can't get out without giving some profit back.

While ETFs are easier to get fills in, the commissions are too high. The problem with SPX is that it's still pit traded and has high volume - usually from big players. My small size seems to be ignored. I don't seem to have the same problem with the RUT. While I'm an ex local, getting rid of the pits couldn't happen soon enough for me. Even with the technological aids that didn't exist when I was in the pit, pit traded instruments are a lot less efficient for retail traders than the electronic traded instruments.
