AlpacaJavaBacktest is a simple and fast Stock Trading Algorithm Backtesting Library for Java that uses <a href="https://polygon.io/">Polygon</a> 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 <a href="https://alpaca.markets">Alpaca</a> in order to get a free API key for Polygon to use this backtesting library. This Library uses <a href="https://github.com/mainstringargs/alpaca-java">alpaca-java</a> exclusively as it contains a Polygon Java API and useful POJO classes. This library is community developed.
