RLS-Adaptive Grid Breakout Strategy

Family: breakout · Regime: trending · Complexity: high · Asset classes: FX, Equities, Indices · Timeframes: H1, H4, D1

Thesis

The strategy assumes that significant price trends begin with a volatility expansion that manifests as a breakout of double-smoothed momentum (TSI_CD) and price structure (Donchian). By using a Recursive Least Squares (RLS) filter, we can adaptively smooth the signal to ignore minor noise. The core edge lies in using volume-profile-derived 'Key Zones' (low volume nodes) for risk management; these zones represent liquidity voids where price is less likely to stall, allowing for high-convexity trades when moving through these gaps.

Components

• Grid Utility (Rosasurfer Framework) (regime) — Defines the volatility regime: when the current price candle height exceeds the calculated GridSize, the market is in an 'Expansion' regime suitable for trend-following.
• TSI Convergence Divergence (TSI_CD) (direction) — Identifies momentum velocity. A positive histogram (TSI_CD > 0) indicates momentum is accelerating in the direction of the double-smoothed trend.
• Donchian Channels (DC) (entry) — Acts as the final execution trigger. A breakout above/below the channel confirms the momentum captured by the TSI.
• SSL Channel (exit) — Provides a trailing trend-exit logic. The 'flip' of the SSL buffers represents a change in short-term trend polarity.
• Dynamic Supply and Demand Zones [AlgoAlpha] (risk) — Uses volume profile 'Key Zones' (low volume nodes) to define structural stop-loss levels and ensure trades are not entered directly into volume-heavy congestion.
• Recursive Least Squares Adaptive Filter (RLS) (volatility_filter) — Filters out high-frequency noise. Entry is only permitted if price is on the 'correct' side of the RLS curve and the RLS error is not expanding (which would signify market chaos).

Known failure conditions

• Price remains trapped within a single Grid Utility level for > 50 bars (extreme low vol).
• TSI_CD oscillates around zero while price remains within the Donchian mid-band.
• RLS P-matrix instability leading to non-finite filter values.
