Combining Parabolic SAR Trend Direction with Bollinger Band Exits

Summary

This strategy combines Parabolic SAR with Bollinger Bands. SAR supplies a directional trend condition, while the bands mark a volatility range: a long entry requires price above SAR but below the upper band, and a short entry requires price below SAR but above the lower band. Positions close when price crosses SAR against the trade or reaches the corresponding outer band. The document also discusses possible filters, volume confirmation, trailing stops, and position sizing as extensions.

The supplied setup specifies a daily ETH-USDT futures backtest window and common indicator parameters, but gives no performance results. The source enters whenever the entry condition remains true, rather than only on a one-time transition, and its exit conditions can close a position independently of whether that position is open. The text warns that choppy markets may generate repeated signals, that results depend on indicator settings, and that the rules have no fixed hard stop or volume filter. These limitations leave profitability and risk control unverified without further testing.

Key ideas

• SAR indicates trend direction, while Bollinger Bands constrain entries and provide outer-band exits.
• Long and short signals require price to be on the trend side of SAR and inside the relevant band.
• The source can repeatedly issue entries while conditions remain true and closes positions when exit rules trigger.
• The published ETH-USDT futures configuration includes no performance results.
• Choppy conditions, parameter sensitivity, and the absence of a hard stop are important caveats.
