Over the years, I have allowed the market to take back what I have taken from it, in the same trade.
In addition, I have advised, more than once, in leaving the original stop where it is, instead of moving it up, at least, to break even. I'm beginning to wonder whether I will, at this late stage, ever learn differently because, no matter how many times one gets stopped at breakeven, at least his account is intact for another trade. Sooner or later, if he is a good trader, one of the trades will keep going.
On the other hand, although I am a great believer in the logic of letting the winners run I find that so many times I get 16 points profit, only to allow the trade to close at a few points loss. Since this happens more times than I can count, it may be more profitable to take this "bread-and-butter" money instead of waiting for the big one. Whatever I do, I should make sure that some profit is locked in with a closer stop.
Many do say that they take 10 points and get out. I think that they could well be right over a longish period, rather than waiting for the profits to run.
