Adaptive Bulge Reversal System
Family: hybrid · Regime: mixed · Complexity: high · Asset classes: FX, Equities, Crypto · Timeframes: H1, H4, D1
Thesis
The strategy assumes that price trends terminate in a predictable cycle of volatility expansion (the Mass Index Bulge). By waiting for this expansion to peak and then using an adaptive Recursive Least Squares (RLS) filter to identify the nascent reversal direction, we can enter a new trend with less lag than traditional moving average systems. The edge lies in the combination of regime detection (MI) and rapid trend-adaptation (RLS/ZLSMA).
Components
- Mass Index (MI) (regime) — Acts as the primary regime filter to identify 'reversal bulges'—points where volatility expansion suggests an exhausted trend is about to turn.
- Recursive Least Squares Adaptive Filter (RLS) (direction) — Provides the master trend direction with minimal lag by adapting its weights to the most recent price innovations.
- Bollinger Bands (Standard) (entry) — Used to time the specific entry point after the regime shift is confirmed, ensuring we enter on a return to mean or a breakout of the value area.
- Ichimoku Kinko Hyo (exit) — The Kijun-sen (Base Line) provides a robust trailing exit and trend-exhaustion signal to lock in profits.
- Custom 004 Liquidity Map with Drawings (risk) — Identifies recent structural support/resistance (20-period High/Low) to set hard stops and calculate position size based on local liquidity.
- Zero Lag Least Squares Moving Average (ZLSMA) (confirmation) — Provides high-speed confirmation of the new trend slope, filtering out minor RLS noise before entry.
Known failure conditions
- The strategy fails in 'staircase' markets where Mass Index fails to reach the 27.0 bulge threshold despite significant trend reversals.
- Failure occurs if the RLS forgetting factor (lambda) causes the filter to track noise too closely, leading to multiple whipsaws at the BB Middle Band.
- The hypothesis is invalidated if price regularly violates the 20-period Liquidity Map levels without a change in trend direction (stop-hunting).
