Use ta-lib library for data minig by Execute Script (groovy)

Hello,

I see the tutorial of Execute Script, that substract the mean of multiple attributes. And I would like to make something samed, data mining from technicial indicators.

First, I have a financial database which describe serial temporally  prices of an instrument of FOREX with the date and five attributes more (O,H, L, C and V). I can read it with rne Read CSV operator.

Second, I have a ta-lib-0.4.0.jar (C:\Program Files\RapidMiner\RapidMiner5\lib\ta-lib-0.4.0.jar) which is an open source and contains a large of technical financial indicators, like RSI, ADX, ...I downloaded it from http://ta-lib.org/hdr_dw.html

I would like to generate multiples attributes, with the name of theese indicators, and the values of them.

Is it possible? How can I do it?

Finally, if it is possible, I would like to do a loop parameters of the some parameters of theese indicators (period, ...)

I am acquantied with RM (blocks) but I don´t know anything about programming groovy. In some posts I read people who ask about how generate multiple attributes and how call a library .jar with the Execute Script but I can´t read some of them, because some links of topics are broken (http://rapid-i.com/rapidforum/index.php/topic,2214.msg8755.html#msg8755)

I have seen this interesting post (Data mining and technicial indicators) but it don´t say haw to do this.

Can anyone help me?

Regards

Ikarus
