Quote from pretzel:
AA,
Some questions:
With partial profit taking, you take the first profit at point X and the 2nd profit at Y. When you did the backtest with all or none, did you take all the profits at point X or point Y ? How do you determine where point X or Y should be without violating the rule of letting profits run? I think if Y is too far out, chances of being stopped out will increase, unless the stop is also a big stop.

Honestly I don't remember all the details, as I did the testing several years ago and the part that stuck with me was the importance of getting as much as possible out of the full position. I am pretty sure that I used the following: a large initial stop that would not get hit much, which would be pulled to break even at maybe 1x initial risk, an exit strategy that tried to hold until the close unless i got a severe breakdown from a swing high (or low if short). I don't think the individual parameters matter that much, except that you want a stop large enough that it rarely gets hit. This is a very stressful trading style, as you put on a trade and hang in there as long as possible. It probably won't work too well in a choppy, rangebound market, but you use entry conditions to try and avoid those markets. It definitely did not trade every day.
