I am swedish, you are french, so I guess my message read differently to you
than I ment to write it. Thus, here is a short hand version:
Look at the first straight line that plots. If the line plots at zero, there
is no bug in Tradestation. If it plots above zero, there is a bug in
Tradestation.
Extended version to the above: If the line does not plot at zero, this bug
gives a lot of concequences, for example in DMI, which is the way I
discovered the bug.
