NQ Implied Range GovernorThis Pine Script v6 indicator, “NQ Implied Range (VIX ÷ √N) Governor”, builds a real-time implied range framework for Nasdaq futures by importing a volatility index (default CBOE:VXN) on a user-selected timeframe and smoothing it with an EMA. It converts the annualized vol reading into a daily 1σ percentage move via oneSigmaPct = (VIX ÷ √252)/100, then maps that into a point-based implied move from a session “anchor” price. The anchor is locked at RTH session start (0930–1600 ET by default) based on your chosen mode (RTH Open, prior bar close, or daily open). A band mode selector controls how sigma is interpreted: an “Intraday Range” mode uses √(2/π) (~0.798) as a proxy for expected max excursion, while close-to-close modes use ±1σ or ±2σ envelopes; a separate calibration multiplier lets you widen/tighten the bands beyond theory.
Once the implied move is computed, the script plots the upper/lower 1.0 bands, the anchor midline, and optional fills above/below the anchor. It then derives symmetric Fibonacci retracement levels between the anchor and each band (.236, .382, .500, .618, .786) and optional extensions (1.272, 1.618), with right-edge price labels for quick reading. In parallel, it tracks realized RTH range (session high–low) and compares it to the implied total range to produce a “range spent” ratio, dynamically color-coded from green → yellow → orange → red as the session consumes volatility budget. That ratio drives a session-end summary label (realized vs implied, bands, % spent), a configurable dashboard table showing model inputs/outputs (smoothed vol, raw σ%, anchor, ± bands, total range, realized, remaining, distance to bands), and a set of alert conditions for key events: crossing spent thresholds (70/100/120%), touching outer bands, touching key fib levels, extension hits, and session start/end.
