The market maker will do what suits him to make him the most monies. We do not have control over what he does. What we can do is align our orders with his. So, if he is low bidding your call option, do not sell it during that day. Wait till the next day. If he was able to buy call options dirt cheap, he will end up flipping it and now be on the ask side and having high ask prices. We can then, undercut him by putting an in between price between the bid and ask and in most cases, will get our order filled. We have also, gotten out at a better price than the previous day.
