RWI Persistence Pullback System

Family: trend_following · Regime: trending · Complexity: medium · Asset classes: FX, Equities, Crypto · Timeframes: H1, H4, D1

Thesis

The strategy assumes that price movement is usually a random walk, but transitions into 'persistent' trends where displacement significantly exceeds the expected standard deviation of a random walk. By using the Random Walk Index to identify these 'non-random' windows, the strategy enters on momentum-confirmed pullbacks (Stochastic/MACD) and utilizes a zero-lag trend-following exit to capture the meat of the move while exiting quickly when the persistence fails.

Components

• Random Walk Index (RWI BTF) (regime) — Acts as a volatility/trend filter to ensure we are not trading in a mean-reverting 'random walk' state (RWI > 1.0).
• EMA Test Fixture (Unsupported For-In Reassignment) (direction) — Provides the primary trend bias. Despite the inert loop in the source code, the functional EMA calculation defines the directional filter.
• Stochastic Oscillator (entry) — Identifies local oversold/overbought conditions within the larger trend for high-probability pullback entries.
• Zero Lag Least Squares Moving Average (ZLSMA) (exit) — Used for trend-following exits. Its zero-lag properties allow for faster capture of trend exhaustion compared to standard MAs.
• Point Based Grid (risk) — Provides a structural 'point-based' framework for setting Stop Losses and calculating position size based on fixed volatility increments.
• MACD (confirmation) — Confirms that momentum has resumed in the direction of the trend following a Stochastic pullback.

Known failure conditions

• RWI stays below 1.0 for extended periods, indicating a permanent shift to low-volatility ranging price action.
• The 50-period EMA flattens, resulting in price 'whipsawing' across the EMA line.
• High correlation between MACD and Stochastic leads to redundant signals without sufficient lag reduction.
