Keltner Channels [NevoxCore]

⯁ OVERVIEW
Keltner Channels [NevoxCore] is a refined KC toolkit: choose EMA (classic) or Session VWAP as the basis, scale band width with an ATR z-score (adapts to volatility in real time), and detect squeezes by comparing KC width to Bollinger Band width. A Trend Gate (EMA) enables bias-aware fills—only shading the basis→trend side—so direction pops instantly. “Return inside” markers flag re-entries from extreme moves, and a tiny risk HUD on the last bar shows distance to the basis and nearest edge.

⯁ KEY FEATURES

Dual Basis: EMA (classic Keltner) or Session VWAP for session-centric trading.

Adaptive Width: ATR z-score scaling expands in high vol, contracts in calm regimes—with min/max clamps.

Squeeze Engine (vs. BB): Detects compression when BB width < k × MA(KC width); clean Start/End states.

Trend Gate & Bias Fill: Gate midline context with an EMA trend; bias-aware fills highlight the active side only.

Return-Inside Signals: Marks when price exits outside a band and returns back inside on the next bar.

Mini Risk HUD: Last-bar label with Δ to Basis and to Nearest Edge (points & %).

NevoxCore Visuals: Pink/orange theme or classic colors; adjustable line & fill opacity.

Alerts: Crosses of upper/lower, return-inside, squeeze Start/End.

⯁ SETTINGS (quick)

Visual

Classic Colors — palette switch (green/red vs pink/orange).

Line Width — basis/upper/lower stroke.

Fill mode — Full, Bias-aware (basis→trend side), or Off.

Fill opacity — transparency for shaded areas.

Show state markers — bottom markers for Squeeze START/END + “RI” (return-inside).

Show mini risk HUD — last-bar label with distances.

Core

Basis — EMA or Session VWAP.

EMA length — if Basis = EMA.

ATR length — for channel width.

Base multiplier — ATR factor before adaptation.

Adaptive Multiplier

Adaptive on — enable ATR z-score scaling.

Z-score lookback — mean & stdev window on ATR.

Z gain — strength of scaling; 0 = visual off even if enabled.

Min/Max effective multiplier — clamps to keep widths sensible.

Squeeze & Trend Gate

Bollinger lookback (BBW MA) — BB width window & smoothing.

Bollinger stdev mult — BB σ for the comparison.

Squeeze threshold — BBW < k × MA(KC width).

Trend Gate — turn on for bias-aware fills & directional filtering.

Trend EMA length — default 200.

⯁ ALERTS (built-in)

KC — Price Crosses Above/Below Upper

KC — Price Crosses Above/Below Lower

KC — Return Inside from Above/Below (re-entry after an outside bar)

KC — Squeeze START / Squeeze END
Tip: For cleaner signals, set alerts to Once Per Bar Close.

⯁ HOW TO USE

Breakout Flow: Look for Squeeze START → END, then watch upper/lower crosses in the trend direction.

Mean Reversion: Fade extended moves when Return Inside fires (add confluence: structure/HTF).

Risk Framing: Use the mini HUD to gauge distance to Basis/Edge for stop/target planning.

Basis Choice:

EMA for classic, instrument-agnostic bias.

Session VWAP for session liquidity anchoring (intraday).

Tuning: Raise Z gain or widen min/max to let bands breathe more in volatile markets; tighten for range days.

⯁ WHY IT’S DIFFERENT
Standard Keltner tools fix width to ATR×k. This build adapts k with an ATR z-score, benchmarks squeezes against Bollinger, and adds bias-aware fills + return-inside logic—all in a crisp NevoxCore layout with practical alerts and a mini risk HUD.
