As an equity trader, I was hit by broken trades serveral times. Are broken trades also possible when trading options ? For example, if you are liquidating a call option after buying it, could you get a call from your broker, telling you, the first buy execution was busted and you're now short. So the liquidation was some kind of "writing a call option" event ? Sorry, if the question is too stupid, but I'm an option beginner and just want to find all hidden traps before getting involved.
