A java stock trading algorithm backtester for users of Alpaca.markets and Polygon.io

AlpacaJavaBacktest is a simple and fast Stock Trading Algorithm Backtesting Library for Java that uses Polygon for historic quotes, trades, aggregates, and other data points to give trading algorithm developers a more accurate understanding of what their algorithm might do in a live market. You should have a live trading account with Alpaca in order to get a free API key for Polygon to use this backtesting library. This Library uses alpaca-java exclusively as it contains a Polygon Java API and useful POJO classes.
