Box-Smoother Pullback System

Family: trend_following · Regime: trending · Complexity: high · Asset classes: Equity Indices, Forex Majors, Large Cap Crypto · Timeframes: H1, H4, D1

Thesis

Market trends exhibit 'staircase' behavior (Boxline structure); after a range breakout, price often reverts to a short-term mean (Williams %R) before continuing. By combining low-lag smoothing (Ehlers) with volatility-normalized exits (Donchian/PSAR), we can capture the meat of a trend while filtering out noise.

Components

• Boxline (Dynamic Range Breakout) (regime) — Determines the regime; price must be trending outside of previous consolidated 'boxes' to trade.
• SuperTrend (direction) — Defines the primary trend bias to ensure the strategy only trades in the direction of established volatility-adjusted momentum.
• Williams %R (entry) — Acts as a mean-reversion trigger within a trend; looking for temporary 'oversold' levels in an uptrend to enter.
• Donchian Channels (exit) — Provides a structural exit signal based on the violation of recent extreme price levels (20-period low for longs).
• Parabolic SAR (risk) — Provides the mechanical stop-loss level and trailing mechanism for risk management.
• Ehlers SuperSmoother Filter (confirmation) — Confirms quality of the move by ensuring price is on the correct side of a noise-filtered curve to avoid minor noise entries.
• GAS Price Levels (volatility_filter) — Filter to ensure volatility is sufficient; trades are only valid if price is expanding relative to the multi-factor structural levels.

Known failure conditions

• Consecutive losses during high-volatility sideways chop where Boxline expands but fails to trend.
• Price remaining pinned between SuperSmoother and SuperTrend for extended periods (compression).
