Thanks
Superfragalist,
I took
a look at one of the charts. I doesn't seem to be screwing up at all. I just
need to understand the "Profit Stop" strategy it is using. The Exits I have set
seem to be working fine.
I
guess I will need to subscribe to Roy's NL.
Thanks, Scott
If you want to understand what the trailing
stop is doing, run the
test and click the plot on chart button. You'll see
how the trailing
stop is screwing up the trades.
The systems tester
is an Access application. It wasn't written by Equis.
You can read
Roy's newsletter. It's a great education in how the
tester works.

Tom S wrote one article that provides
information on his experiences
with it. It's in the file section.
There are work arounds for most of the problems. A lot of it is
about
experience. Things like having to reset the ST-Data file aren't in
the
manual. They've been posted on both boards before, you just have
to
look them up.
