Parabolic SAR Trailing Stops for Trend Following

Summary

This strategy uses Parabolic SAR as a dynamic stop and reversal level. It places long or short stop entries around the indicator, then exits when price crosses the level. The indicator’s acceleration settings control its starting value, increment, and maximum, while a date window is provided for backtesting. The published configuration describes testing BTC-USDT futures over a one-month period using four-hour bars and a fifteen-minute base period.

The document presents the approach as a way to follow strong trends while adjusting exits as prices move. It also identifies key limitations: SAR settings can make stops too tight or too loose, a single indicator may react poorly to unusual moves, and sideways markets can generate repeated exits. The sample code’s stated window function always returns true, so the date inputs do not appear to restrict entries as described. No performance results are reported, and the brief backtest configuration does not establish robustness or live-trading behavior.

Key ideas

• Parabolic SAR supplies a moving level for trend-following entries and exits.
• The strategy uses SAR parameters for its starting value, increment, and maximum.
• The document warns that sideways price action may trigger frequent stop-outs.
• The source code’s window function always returns true, so the date inputs do not enforce a test window.
