Thanks for the answer. Indeed, once the turn is confirmed it should
be ok. But why the System Tester doesn't take this into account too?
Now, the Tester leaves a lot of bad signals, altough it was a valid
cross of the CLOSE with the PEAK. I think it is because the system
buys only the next day. Maybe I should buy at the close of the
signal bar instead of the next open. That's possible but i don't
know how to formulate it in the tester. You know this by heart?
rgds,
Dirk
