Ruby Technical Stock Indicators Library

I am looking for a “stock indicator library” written in ruby. A technical indicator can be anything from a moving average to Williams% R.

I need a library where I can provide historical data for stock (input) and get the last value for any technical indicators as an output.

I am also interested in any such open source libraries written in any other language.

I did some searches and I searched here, but so far no luck.

Thanks.

There is a TA-Lib Ruby gem that wraps the already well-developed technical analysis of the C ++ library http://ta-lib.org/

Having said that installing all the components on Ubuntu was painless or absent from working with its own packages (there is a third-party Debian repo, but ymmv).

Quantlib in R seems to be open source. In fact, it prompted me to learn how to embed certain R-operations in Ruby, until I was completely discarded by crutches and code in R.

For some reason, the Python community is much more prone to crunching than the Ruby community, see this for information on what Python support has: Financial technical analysis in python

If you don't mind some of your own calculations, a ruby ​​is a great choice.

Check out the ruby ​​project I wrote that updates the csv table with new daily values ​​and calculates some moving averages. It is used to generate this page daily: https://sites.google.com/site/sandp500daily/fri-sep-21-2012-snp-500
