USDX-EVZ Volatility Expansion Hypothesis

Family: trend_following · Regime: trending · Complexity: high · Asset classes: Forex (Major Pairs) · Timeframes: H1, H4

Thesis

Price trends are most sustainable when domestic momentum (CCI) is confirmed by institutional footprint (FVG) and broader macro imbalances (USDX). By filtering these entries through implied volatility (EVZ) and dynamic ranges (Boxline), the strategy enters during high-probability 'expansion' phases while avoiding the 'noise' of low-volatility ranging periods.

Components

• Heikin-Ashi Candles (regime) — Determines the local trend regime; only trades in the direction of the smoothed price flow.
• USDX (US Dollar Index) Candle Indicator (direction) — Provides global macro direction; ensures the trade is aligned with U.S. Dollar strength/weakness which drives FX markets.
• CCI Arrows (entry) — Captures momentum shifts as price crosses the zero midline to trigger the entry.
• Bollinger bands / Connectable [Azullian] (exit) — Identifies mean-reversion points or exhausted volatility for exits when price touches outer bands.
• Euro FX VIX (EVZ) Data Loader (risk) — Quantifies expected market fear/volatility to scale position sizes inversely to perceived risk.
• OrderBlock FVG Detector (confirmation) — Confirms the entry by ensuring price is reacting to a structural Fair Value Gap or Order Block.
• Boxline (Dynamic Range Breakout) (volatility_filter) — Filters out low-volatility 'noise' by requiring a range breakout before considering signals.

Known failure conditions

• EVZ data source becomes desynchronized or unavailable, rendering risk management impossible.
• Long-term consolidation periods where Boxline expansion leads to repeated CCI whipsaws.
• A breakdown in the historical correlation between USDX and the traded currency pair.
