APS- Automatic Pattern Search

:p :p ,

>Basically, it uses a set of generic pattern groups - up to 88 in number - and the seaach is based on those.....

I didn't know, that i am discussing with the developer of APS...

The only difference, i can see, is that APS does a walk forward analysis (like VectorBull).
This would have to be done manually in Tradestation by not using the whole time period for evaluation.

For those, who have Tradestation, this is the better alternative.

Be serious now. Someone asks a question about another program and you come along with a black box trading recommendation.

Don't you understand that these two program, APS and VectorBull cannot even be compared? The former is a white-box and the latter is a black-box with signals probably optimized to death.

This price pattern discussion reminded me of that oldie-but-goodie "Day Trading With Short Term Price Patterns and Opening Range Breakout" by Toby Crabel.

It's actually a really good treatment on how to conbine several unrelated statistical edges to create trading systems. His discussion on price patterns was quite interesting.
 
I've created something like APS as an academic exercise. Basically, patterns are generated in one of several ways, through genetic evolution, according to a logical price action model, or datamined from historical data. These patterns are then out of sample tested. One of the main issues, especially for eod data is validating the pattern; is it statistically significant? I also find that taking a price ohlc data only pattern discovery approach is a bit crude. Lastly, I believe that a more sensible approach is to form a custom logical model and then datamine to validate the specific pattern as opposed to generating patterns and then figuring why or how they work.
 
Oh, you are a consultant, too ? :eek:

I will ask the guys of VectorBull, if they need your advice :D

If so, please do not forget my commission :cool:
 
 
I don't know about vectorbull because I have never used it and it may be a good program but what it does, based on the website presentation, cannot be compared to APS functionality simple because they are two different programs for different use.

Vectorbull appears to be a real-time market monitoring and signal generation program based on some specific trading algorithms, which may be profitable or not, I have not tested it and I do not know the answer.

APS is aprogram that finds price patetrns based on user defined performance parameters, like the success rate, number of historical trades and max. number of consecutive losers. It is a "white-box" as someone mentioned already in the sense that it reveals the code of the patterns it finds.

APS belongs to the class of automated trading system discovery programs, which are very different from black-box signal generation programs:
