TA-Lib is a set of libraries providing common functions for the technical analysis of financial market data. It contains over 130 TA indicators and offers candlestick pattern recognition.
TA-Lib is being developed by Mario Fortier and others at http://www.ta-lib.org. It is released under the terms of the BSD License.
My original motivation for packaging TA-Lib for Debian was that Qtstalker (as of version 0.34) depends on TA-Lib. I am the maintainer of the Qtstalker Debian packages.
I am working on getting the TA-Lib packages into the official Debian distribution (here is the ITP-bug). Until then, you can find the packages here at my site.
The easiest way is to just add the following line to your /etc/apt/sources.list:
deb http://www.zwets.com/debs unstable/
deb-src http://www.zwets.com/debs unstable/
and the packages will magically show up in your package manager. (Note: you need the second line only if you want to obtain the source code.)
The package you will be looking for (as a developer) is ta-lib-dev. That package gives you the header files and .so links needed to build software against the TA-Lib libraries.
The ta-lib-dev package will automatically pull in the package
containing the run-time library: libta-lib0.
