Most trend following systems recommend you have a trailing stop in order to lock in profits. I often find that if the trading stop is too close the positio9n quite often stopped out before the "meat " of the move occurs. If it is too far, it will give the trade the change to capture the "meat" of the move however a big chunk of the "meat" is given back when the position reversed and gets stopped out. For a long time I have been researching this problem and, although I do recognise that there is to "correct" solution, I think some approaches must be better than others. Here are one or two of my own ideas 1) Start with a wide stop and gradually reduce the stop value as the position moves into your favour, so that you capture increasing more and more of your profit. 2) Have a predetermined profile level which your analysis indicates that is likely to be hit, take your profit and forget about what might or might come later. Any ideas from ET members would be appreciated.
