It looks to me like TA-Lib is a Technical Analysis library (read indicators like MACD, RSI, Stochastics, etc) and Quantlib is about Quantitative finance and include a sha-load of very cool tools…

If your AI isn’t do’in TA internally then what is it doing in there? ;-)

Rapidminer + Quantlib = very interesting…

Throw in some nice data wrangling and your king of the world 8^)

Maybe what Rapidminer needs is a slick scripting language so you could hack up a io/pre/post processor without having to whip-out the entire devo build chain…

I am referring to TA-Lib as a set of technical analysis pre-processing operators (http://www.ta-lib.org) and/or QuantLib (http://quantlib.org/index.shtml). I am strongly leaning towards TA-Lib as I dont know of anyone at an individual level that would use all of the power of Quant Lib. That seems to be geared more towards high end quants & institutions.

I will draw up a process flow with what I envision as the whole financial ‘modeling’ process and then we can plug in the pieces with what is needed. I could envsion a 1)Data Feed Handler, 2) Technical Analysis Pre-Processors, 3) Messaging Queue (to initiate a buy or sell order from an execution platform) and probably some more operators that I cant think of at the moment.

Eric: Are you referring to Mathlab libraries? I’ve been thinking about this for a while myself but I was leaning more to a database driven query system, but something like this would be vastly easier. Unfortunately, I very little Mathlib experience from my Freshman year in Engineering. That was a long time ago.

Ralf & I had talked about adding some sort of financial time series pre-processing operators to reduce the work that would need to be performed outside of Rapid Miner prior to building a model.

Two existing java libraries for this functionality came to mind – TA-Lib & QuantLib. I think TA-Lib may be more useful & easier for most users to use & understand.

Any thoughts on adding these operators? I know you have more experience with the product than I do so any insight you have would be great. I haven’t fully thought out what all I think would be useful to have, but I am sure we can make generate some good ideas for the product.

Feel free to email me to discuss further.

Regards,
Eric

Very cool…

I hope this means we will see some more tutorials from you soon dude ;-)

Also like the new format of your site… Its on topic 8^)

Keep up the good work!!!
