TA-Lib library - http://ta-lib.org - is a multi-platform tool for market analysis. TA-Lib is widely used by trading software developers requiring to perform technical analysis of financial market data.
This module provides an PDL interface for TA-Lib library. It combines rich TA-Lib functionality with excelent PDL performance of handling huge data.
If you are not a PDL user you might be interested in Finance::TA module which provides approximately the same set of functions working with common perl data structures (which is fine if you are not about to process large data sets and if you generally do not worry about performace).
