WallStreetAnalyzer = TradeAnalyzer
I saw a demo at the NY Online Trading Expo 2 weeks ago.
They were displaying it with a black box system using about 30 stocks.
The equity curve on the displayed system was a straigh upward slope. Very
impressive equity curve. If you buy it they will never disclose the rules.
They kept on repeating 'trust us" it works.
===
Depends if the black box was running on unseen data or not...
It's easier with training data.
The way it works is that it has a set of indicators. You can't add to it.
If you want to create a new indicator you MUST ask them
to program it. It's fully compiled, so it runs much faster then TS.
That was their only selling point. They kept on bashing TS.
====
This may be true. A compiled software amy run faster that TS because a lot of
features are removed from the language ( including bacward memory storage for
indicators, functions...).
Bashing TS has never been a good commercial practice. See Volker.
Have you seen me bashing TS? No, of course.
However I sell similar stuff, that runs faster than TS too.
I guess they were able to compile it because they don't have to worry
that the user will create a new indicator.
It uses 'scripts' to combine different indicators into a system.
===
This is the general structure of such programs.
Either they run NN or rulebase code, optimize them usign GA or other algorithms.
The major drawback is that it's often pure curve fitting with no control of the
generalization while training.
Surprise may often occur later, in realtime.
The demoer was French :)
===
They are terrible.
