With all respect to the person I was doing the test with, the difference
between the results were so minor that even me, as a German, called it
EXACT. Anyone knows that each software has different rounding procedures
and that this can cause differences at some time. We have published many
systems based on the portfolio capability and have more licenses sold
then we have ever dreamed of. It was like trying to discuss with Pierre
about the differences between WLD and TS (oh no please Pierre ... don't
jump in again and tell me that I should not answer this question here, I
did not mean to offend you) ;). I did not finish this comparison because
of the way people in the TraderClub forum where treating me WITHOUT
knowing the facts. No one ever asked for the exact difference of the
number, no one, but preferred to call me a liar. In fact I know that
many of the aggressive once came from the same source.
Anyway, our whole web site allows you to do portfolio back testing on
stocks for free. Just go there, pick a simple system and test it on the
NASDAQ 100 stocks or the DOW 30 stocks.

Betreff: RE: portfolio results in TS?
Volker,
I have no idea what sort of disagreement or considerations prompted the
previous abandonment of the test comparing Trading Recipes with
Wealth-Lab,
but it would be helpful if this or a similar test would be completed and
the
results published. I previously asked you about this on this list, and
you
pointed me to a forum where people were talking about how much they like
Wealth-Lab, which really doesn't tell me anything about how accurately
it
handles portfolio level testing for futures.
I am intrigued by Wealth-Lab, despite its intimidating-looking
programming
(and I am a former professional programmer who knows Pascal...), and
certainly have no negative ax to grind regarding Wealth-Lab, but I'm a
little dismayed by the non-completion of this test, and can't understand
why
you would not want to complete it and publish the results if they would
show
your product in a good light.
