Sunday Gap Momentum Regression Strategy

Family: trend_following · Regime: trending · Complexity: medium · Asset classes: Forex, Commodities, Indices · Timeframes: H1, H4

Thesis

Market momentum is often established by price discovery occurring over the weekend (Sunday Gap). If this gap aligns with a medium-term ROC and breaks through technical pivots, it indicates a high-conviction institutional trend. By using the Standard Error of Regression to measure 'trend quality,' we can place stops outside the linear noise of the trend, and use a zero-lag EMA (McNicholl) to capture the meat of the move before it reverses.

Components

• Sunday Opening Gap (regime) — Establishes the weekly bias; if the gap is bullish and remains unfilled, the week is treated as a momentum regime.
• TA Coverage Probe (ROC 14) (direction) — Provides a standard momentum verification to ensure the price movement aligns with the structural gap direction.
• SuperTrend & Pivots (entry) — SuperTrend acts as the primary trigger for entry, while Daily Pivot points provide a structural filter to avoid entering into immediate resistance.
• McNicholl EMA (MCNMA) (exit) — Its zero-lag properties allow for faster exits when the trend reverses compared to a standard EMA, protecting capital in mean-reversion spikes.
• Standard Error of Regression (STDERR) (risk) — Quantifies price dispersion around the trend; used to set dynamic stop losses that expand during volatile, noisy periods.

Known failure conditions

• Price fills the Sunday gap and remains stagnant for more than 48 hours.
• STDERR values reach historical extremes, indicating a total breakdown of linear trend behavior.
• Daily Pivot levels (R2/S2) are reached within the first 4 hours of the week, suggesting exhaustion.
