Pierre,
I find your mails here regarding a user of WL rather childish. Let me sum up
what you are trying to say:
1. A user developed a system that you believe is impossible and he published
it on a French forum.
2. He may have over optimized a whole portfolio.
3. He may have made an error in programming it.
Now you conclude that there is a "bug" in Wealth-Lab; that is obscene (to
say the least).
If your argument is right then just think of the many system vendors that
sell systems based on the "BOUNCING TICK" calculation of TS or the once that
sell systems that are just optimized on one market.
I even remember there is a guy from France that is trying to sell a fuzzy
logic add on to TS for an outrages price, who still has not proven that it
produces superior results.
In any case, your continuous comments about ONE customer on a French forum
show me that you lack further arguments which I take as a compliment.
After all if TS would have included:
Portfolio Level Backtesting
Portfolio Level Money Management
Portfolio Optimization (in one run)
Portfolio Scanning
Drag and Drop Programming
Drag and Drop of Indicators
Drag and Drop of Indicators of Indicators
A huge community that has a platform to exchange ideas
Develop, Test and Scan on the web site it self
...then may be we would have never developed WLD3. This brings me back to my
earlier comments, that we are leading the way and show other products what
to include.

***Thanks. Interesting.
***==
***Yes, is it not?
***
***Piping the site through http://babelfish.altavista.com resulted in
***an English translation that roughly conveyed to me what was going
***on, but I'd like you to clarify.
***===
***Well, this should achieve the same level than my english...
***
***It seems that people have come up with trading strategies in WL that
***give optimistic results to the point of absurdity. And yet (as
***far as I can tell from reading) these strategies don't "cheat" by
***looking at future prices. Correct?
***===
***We never saw the code of this systme, but it seems that the thing was
***based on a
***similar bug that was not obvious to the WL customer ( who still do not
***believe
***that there was a problem in his system).
***
***I am curious if the same system logic programmed on TradeStation
***would yield similar results, and if not, why not. In other words,
***is the ridiculous equity curve shown the result of poor programming,
***or the underlying backtesting platform?
***===
***Because the source code was not disclosed, it was impossible to do so in
***TS (
***and anyway TS do not allow such results, unless you use a DLL that reads
***prices
***in advance, but here you cannot invoke a bug).
***
***I am interested in the answers because I have always been interested
***in any trading / backtesting platform that has additional
***capabilities lacking in TS2000i (specifically portfolio testing,
***optimizing on custom calculated results, and a one-time purchase
***price rather than rental like TS7).
***==
***We hae had several systems like this published on this site. Some were
***tested on
***Metastock or Amibroker( not sure for this one). The probem is for real
***and was
***observed on several platform, poorly programmed, unsecure or even
***seriously
***bugged.
***TradeStation is still the exception in the magic domain of the Mickey
***Mouse
***TradingSystem World.
***
