Rationale for exit point
Reading this forum and other sources, it appears that the pros exit their position before expiry. They usually have some sort of target/benchmark to exit eg. 50% of of max profit potential.
There must be good reasons but I can't see why. For example, you have a butterfly initiated one month before expiry. It is now 5 days before expiry and the price is at the sold strike. A large chunk of the profit (approx. 1/2) can be realised in the next 5 days. Why would one exit now and only realise 1/2 the max profit? Why not wait till expiry and get the full profit?
The only reasons I can see are:
1. Exit while the price hovers around the sold strike to avoid the risk that price runs away from the sold strike in the last week.
2. Pin risk.
Are there other more valid reasons to exit before expiry? Or am I making a wrong assumption that professional traders do not exit at expiry? Any comments/words of wisdom/thoughts/enlightenment is much appreciated.
