Combining 123 Reversal Signals with Percentage Change Thresholds

Summary

This strategy combines a 123-style reversal signal with a percentage-change filter. The reversal component compares recent closing prices and the relative position of fast and slow Stochastic lines around a central level to identify possible directional turns. The second component measures the price change over a configurable lookback and signals direction when the change exceeds a positive or negative threshold. The strategy enters only when both components agree and closes positions when they do not.

The document argues that combining reversal and momentum-like signals may filter some trades, but supplies no performance results to establish that benefit. It warns that disagreement can mean missed opportunities, thresholds are parameter-sensitive, and a shared incorrect signal can still cause losses. The published example uses BTC futures settings, but gives no reported outcome. Suggested refinements include testing parameter stability across instruments and timeframes and adding stop-loss rules.

Key ideas

• The 123 component uses recent closes and fast-versus-slow Stochastic readings to form reversal signals.
• A percentage-change threshold supplies a second directional signal over a configurable lookback.
• Positions are taken only when both components agree and are closed when the combined signal disappears.
• Signal agreement can filter entries but may also reduce trading opportunities.
• Parameter sensitivity and incorrect matching signals remain risks, and no performance results are reported.
