for the successful traders, do you guys get more shares when the stock pulls back or do you take your profit and try to establish a new position when it continues trending. For example if the stock is downtrending and you get short at 19.50, it drops 5 cents but it looks like it is going to pull back, do you get out and look to short again. Or do you lose some of your profit as it retraces (you don't get ANY shares out) and you short more. I have a hard time holding on for big winners because I hate lose the profit I just made. How do you guys hold for a bigger profit? Do you just not watch it?
