NOA Sessions Footprints
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT IT DOES
This indicator tracks up to 4 configurable intraday sessions (or ETH/RTH/Full Day) and overlays real-time order flow analysis using TradingView's footprint data. It draws session boundaries, calculates statistical projections from historical data, and detects 8 distinct footprint signatures on each bar.
Each session gets its own VWAP, midline, expected range projections, overnight gap tracking, and a live dashboard comparing current metrics against historical averages.
When a session closes, it receives a Macro Profile classification (Trend / Reversal / Rotational) based on session-level order flow.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
STRENGTHS
— Uses actual footprint data (bid/ask volume at price), not synthetic delta approximations.
— All thresholds are statistically derived from the instrument's own history via Z-scores, not fixed values.
— Outlier filtering (trimmed mean) prevents news days from distorting projections.
— Each signature requires multiple independent filters to fire. No single-condition signals.
— Works across any intraday timeframe on any instrument with footprint data.
— All signatures respect a configurable bar-close gate to prevent intrabar flickering.

THE 8 FOOTPRINT SIGNATURES
Organized into three groups.
GROUP 1 — INITIATIVE (Trend Continuation)
📶 Stacked Initiative
Consecutive bars where delta, candle direction, close-over-close advancement, and POC advancement all align. Requires minimum delta intensity and total streak displacement. Detects sustained institutional order flow.
⚡ Large Body
Single bar with a body Z-score exceeding the configured threshold. Optional aligned delta requirement. Detects statistically abnormal directional repricing.
GROUP 2 — EXHAUSTION & REVERSAL
🩸 Delta Squeeze
Bar where 40%+ of volume is aggressive delta in one direction, but close is in the opposite direction. The aggressive side committed heavy flow and lost the bar. Detects passive absorption with contrary displacement.
💀 Exhaustion Print
Bar at a session extreme (new high/low) with climactic volume Z-score and aligned delta, but price rejects to close in the opposite half of the bar. Detects the final push of a move.
🧲 Divergence
Bar that sweeps a session extreme, but delta is counter-trend, close is directional against the sweep, and close finishes outside the Value Area on the rejection side. Four independent filters. Detects liquidity sweeps / stop hunts.
🛡️ Absorption
Bar with volume Z-score exceeding the effort threshold, body smaller than a fraction of average (low result), and opposing delta. Detects iceberg / limit-order walls.
GROUP 3 — REGIME SHIFTS & TRAPS
🪤 Trapped VA
Bar where the open sits entirely outside the current bar's own Value Area (by a configurable multiple of the VA range), with a confirming directional close and aligned delta. Detects intrabar liquidity traps where traders positioned inside the VA are caught offside.
🔄 CVD Flip
Bar where the session's cumulative volume delta crosses zero. Marks the point where net aggression shifts from buyers to sellers or vice versa. Context signal for directional bias.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
MACRO SESSION PROFILE
When a session closes, it is classified as one of:
[⚡] Trend — Session body exceeds Z-score threshold with aligned CVD.
[💀] Reversal — High session volume, opposing CVD, close in favorable half.
[🛡️] Rotational — High session volume, tiny body, opposing CVD.
The classification appears as a bracketed icon on the session label.

SETTINGS OVERVIEW
General
— Indicator Mode: Intraday (4 sessions) / ETH / RTH / Both / Full Day.
— Lookback Period: Number of historical sessions for averages and Z-scores. Default: 20.
— History Length: How many past sessions to keep drawn on chart. Default: 20.
Footprint Engine
— Wait for Bar Close: Suppresses signatures until bar confirms. Default: On.
— Footprint Ticks per Row: Footprint resolution. Default: 10.
— Candle VA %: Volume percentage for Value Area calculation. Default: 40%.
Signature Toggles
— Each of the 8 signatures can be independently enabled/disabled.
— Each has its own configurable thresholds (Z-scores, delta %, multipliers).
— Stacked Initiative has additional sub-filters: minimum delta %, streak displacement requirement.
Signature Colors
— Three group-level color pairs (G1 Initiative, G2 Reversal, G3 Shifts) instead of per-signature colors.
Statistical Projections
— Expected Range: Average / SDev / Both / None. Projected symmetrically from session open.
— SDev Multiplier: Default 2.0 (≈95% probability zone).
— Outlier Exclusion: Trims top/bottom 5% of historical data.
Gap Detection
— Draws overnight gap boxes with configurable duration, mid-gap line, and directional coloring.
— Gap Z-score and multiple-of-average statistics appear in session tooltips.
Alerts
— Independent toggle for each signature plus Expected Range crossings.
— All alerts fire on confirmed bars only.
Heatmap Thresholds
— 🔥 ≥120%, 🌡️ ≥100%, ☁️ ≥70%, ❄️ <70% of historical average.
— Applied to range, volume, and CVD on session labels.
Dashboard
— 12-row table comparing Historical vs. Live metrics per session.
— Rows: session range, volume, CVD, bar range, bar body, bar volume, daily gap, hit rates.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
REQUIREMENTS
— Intraday timeframe only.
— Instrument must have TradingView footprint data available. A warning is displayed if footprint data is unavailable.
