    QChartist

    QChartist

    Free and Open Source Technical Analysis Charting Software

    QChartist is a free and 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 any 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. It is also possible to filter or merge data. I got a little inspired from MT4 allowing a fairly easy portability of programmed indicators from MT4 to QChartist. It is now faster and much more professional thanks to the use of a C++ layer (used mostly for calculations) over the standard Basic layer (used mostly for the GUI interface). You can use astro indicators and functions from a library for astronomical calculations. You can get real time quotations thanks to Yahoo Finance, Alpha Vantage, Tiingo, Stooq, Finnhub and Twelvedata data sources.
