# Turtle Trading This strategy is based on the Turtle Trading method created by Richard Dennis and William Eckhardt. It is a simple trend following strategy based on breakouts. ## Rules 1. If the asset (e.g., SPY) exceeds its highest high over the past 20 days, enter a long trade. 2. Exit the trade when the asset drops below the lowest low over the past 10 days. ## Parameters **High Period**: The period over which to determine whether price has exceeded the highest high for entering a trade. (Default: 20) **Low Period**: The period over which to determine whether price has dropped below the lowest low for exiting a trade. (Default: 10) ## Backtest Results ### SPY ![SPY Analysis](https://static.moshington.com/images/strategies/turtle-trading/spy-analysis.png) ![SPY Summary](https://static.moshington.com/images/strategies/turtle-trading/spy-summary.png) ### QQQ ![QQQ Analysis](https://static.moshington.com/images/strategies/turtle-trading/qqq-analysis.png) ![QQQ Summary](https://static.moshington.com/images/strategies/turtle-trading/qqq-summary.png) ---
