I don't mean to be calling you names, but it just does not seem to be a good strategy to play like that - which I mean is selling at about 55% retracement.. and the practice should not be different whether you are holding a lot or holding a little, and probably the most convincing mistake is that either you had not sold enough earlier or you had invested too much (even if it is a small amount)... but yeah, it is understandable that each of us have to do what ends up being comfortable for us... and hopefully learn how to improve our methods so we don't do the opposite of what would be a better practice (buying on the way down - or worse case scenario, just HODLing)
