The Market Analysis System (MAS) is an open-source software application that provides tools for analysis of financial markets using technical analysis.
MAS provides facilities for stock charting and futures charting, including price, volume, and a wide range of technical analysis indicators. MAS also allows automated processing of market data — applying technical analysis indicators with user-selected criteria to market data to automatically generate trading signals — and can be used as the main component of a sophisticated trading system. It operates on both daily and intraday data.
MAS is a flexible system that can be used either as a personal tool or, making full use of its client/server architecture, it can be installed on a powerful server and configured to serve many clients at the same time.
