Hi Yuki

Thanks for the clarifications. I will be examining different exit 
strategies after reading your posts. I assume that when you mention 
being taken out of a trade by a signal, you mean maybe a signal from the 
system that got you in or maybe a signal from another short-only system 
(I hope this distinction makes sense - the whole reason I am looking at 
these stops is that I have systems that are not designed to be always in 
- that is, they are designed to trigger trades in one direction only). 
While typing this, I just realized that I have not examined the concept 
of a signal that says "Close your longs but that doesn't necessarily 
mean go short". I have seen reference to these kinds of signals and 
maybe they are a bigger part of winning systems than I have realized.

I have a lot to learn, obviously.

You said

I think you'll find most people here will report that performance of
their best systems degrade with the use of *any* stops.

Ok - I am trying to understand this. So do you mean that exits are 
discretionary? Hmmm... I doubt that's what you mean, but maybe....Or 
maybe you mean that they are always in so they are stop and reverse, 
thus obviating the need for a 'stop'.

Anyway, I have some sense of direction now, so...once again to all who 
have helped me out, thank you.

I think you'll find most people here will report that performance of
their best systems degrade with the use of *any* stops.  Not all of
course, but I suspect most.  I've seen the comment again and again,
and it's my own experience as well.

The majority meet with failure because of their lack of persistence in creating new plans to take the place of those which fail.
