class=890323012-29112003>Sorry, I'm not trying any of this, which probably means
I'm wrong... It seems to me that if Gary's right about needing to use LastValue
on the stopType ApplyStop parameter, that says it can't change over time. Check
out the help for LastValue. You'll see that it returns the single last value in
an array, so your stop is always one type or the other; it doesn't change
dynamically.

stops, one a stop loss and one a trailing stop, whose parameters you'd
change to make one effectively the active one.

changed the volitility parameter to "True." But when I do an exploration I
see the same thing ... when the price drops below 30 pips of profit it
reverts to the 50 pip stop loss (within a single trade).
