ATR Trailing-Band Direction Flips with Regime Filters and Sizing Controls

Summary

The STP Flip strategy uses an EMA-centered band widened by an ATR multiplier to determine direction changes. It is designed to remain in a position until the indicator flips, with optional per-trade profit or loss limits and a trailing profit stop. Settings include a ratcheting trail that tightens but does not loosen, an optional volatility-adaptive multiplier, and filters based on higher-timeframe bias, volume, trend alignment, volatility expansion, breakout distance, and market-regime scores derived from ADX, choppiness, and regression fit.

The position-sizing design starts with a base contract quantity and can multiply size after each flip; optional controls instead cap the progression, require confirmation before reversing, or suppress flips during choppy conditions. The supplied document is a partial source excerpt, so several implementation details and defaults cannot be reviewed here. It offers no performance results or empirical evidence that its filters improve outcomes. In particular, geometric size increases can compound exposure during repeated reversals, and any trailing or regime logic requires instrument-specific testing with realistic costs and execution assumptions.

Key ideas

• An EMA center and ATR-width band define a direction that changes when price crosses the trailing boundary.
• The default management concept is to hold until a directional flip, with optional trade-level limits and profit trailing.
• Optional filters assess trend, volume, volatility expansion, breakout distance, and choppy or trending regimes.
• Position size can increase geometrically after flips, while smart-sizing and flip-confirmation options provide alternative controls.
• The excerpt gives no verified performance results, and increasing size after reversals can raise risk substantially.
