QChartist (QCH)

“QChartist is a free, open-source technical analysis charting software. Its purpose is to provide a complete set of tools to perform technical analysis on charts and data. It helps to make forecasts mainly for markets but can also be used for weather or quantifiable data. The program is flexible, and its functionalities can be easily extended. You can draw geometrical shapes on your charts or plot programmable indicators from your data.

Many paid charting software are available on the market, but good free software is rare. The project started in 2010. I needed flexible software for technical analysis purposes. Since then, the program has become more and more professional.”
