Adaptive EVZ Volatility-Expansion Hybrid

Family: breakout · Regime: trending · Complexity: high · Asset classes: EUR/USD Forex · Timeframes: H1, H4

Thesis

EUR/USD breakouts are most sustainable when accompanied by an expansion in both historical volatility (Bollinger Bands) and forward-looking expected volatility (EVZ). By timing entries with a cycle-adaptive momentum oscillator (SAM) instead of static-period indicators, we can capture the meat of a volatility-expansion move while filtering out exhaustion using Elder's Bulls Power. The core edge lies in volatility-adjusted position sizing, which prevents catastrophic drawdowns during high-uncertainty events reflected in the EVZ.

Components

• Bollinger Bands (Standard) (regime) — Identifies volatility expansion (squeezes) and defines the outer boundaries for trend 'walking'.
• EMA with Switch-Based Length Reassignment (direction) — Provides a micro-trend filter to ensure price momentum is aligned with the immediate directional bias, even with its dormant switch logic.
• Smoothed Adaptive Momentum (entry) — Captures cycle-tuned momentum entries, filtering out noise via the SuperSmoother to find high-probability entry points within a trend.
• Risk Reward Indicator Tool (exit) — Standardizes the exit logic using a fixed reward-to-risk ratio based on the initial volatility-defined stop.
• Euro FX VIX (EVZ) Data Loader (risk) — Uses external forward-looking volatility expectations to scale position size; high EVZ leads to reduced exposure to account for wider price swings.
• Bulls Power (Elder-ray) (confirmation) — Confirms that the underlying pressure from buyers (highs relative to EMA) is sufficient to sustain a breakout.

Known failure conditions

• EVZ data becomes stagnant or fails to update, leading to incorrect risk calculations.
• The Homodyne Discriminator in the SAM fails to find a dominant cycle in a trending 'runaway' market, leading to late entries.
• Market volatility drops below the BB squeeze threshold for extended periods (flatline).
