The stockmonkey distribution is supposed to contain all the technical analysis tools you'd ever want. It has a few things, but it's sadly lacking. Here's the tiny catalog so far: Math::Business::SMA Simple Moving Average Math::Business::EMA Exponential Moving Average Math::Business::MACD Moving Average Convergence/Divergence Math::Business::RSI Relative Strength Index Math::Business::BollingerBands Bollinger Bands Math::Business::ATR Average True Value Math::Business::DMI Directional Movement Index (aka ADX) If you'd like to help, or even just *suggest* a module, just let me know. Links to the algorithm are helpful as our spreadsheets with example calculations, but they are not necessary. I do check rt.cpan.org, so that's definitely one way to go. https://rt.cpan.org/Dist/Display.html?Status=Active&Queue=stockmonkey - jettero@cpan.org
