Institutional Session VWAP Bands (Zeiierman)

█ Overview
Institutional Session VWAP Bands (Zeiierman) plots a clean, session-aware VWAP that restarts at the “True Close” (end of the first trading hour) for each session you enable (Sydney, Tokyo, London, New York). From that anchor, the script computes a classic volume-weighted average price plus optional standard-deviation bands to frame session fair value and dispersion.


By aligning VWAP to when institutional flows settle (the first hour), you get a reference that matches real execution behavior, yielding more credible pullbacks, retests, and mean-reversion reads inside each session.


█ How It Works

⚪ Session Detection
You choose the sessions (on/off), their UTC-aligned time windows, and colors. The script detects when each session is active on your chart timeframe.

⚪ True-Close Anchoring
At session open the indicator waits. When the first hour completes, it flips the anchor on and starts a fresh VWAP for that session, mirroring how many desks treat the first hour as the real close for the prior day’s positioning.

⚪ VWAP Core
From the true-close anchor, VWAP is calculated in the standard way: cumulative (price × volume) / cumulative volume using your chosen price source (default hlc3).

⚪ VWAP Bands (σ)
Upper/Lower bands are built using a running standard deviation of the price source since the anchor. You control the σ multiplier and line width, and you can optionally fill between the bands.

█ Why Sessions + True-Close Anchoring

⚪ Institutional Timing Matters
A new anchor at the first-hour close reflects where real flows have settled, giving you a session fair-value line that aligns with how many funds evaluate prices intraday.

⚪ Cleaner Session Reads
Because VWAP and σ-bands restart each session, your retests, squeezes, and mean-reversion signals are based on today’s order-flow context, not yesterday’s inertia.

Result: a session-true fair-value with dispersion bands that stay close to the action, improving the quality of pullback entries and risk framing.

█ How to Use

⚪ Session Fair-Value Guide
Treat VWAP as the magnet for intraday value. Impulsive moves away from VWAP that fold back often present retest opportunities.


⚪ σ-Band Reversion & Breaks
Reversion: Tests beyond the upper/lower band that snap back inside can flag exhaustion.

Trend: Price riding the VWAP band in a strong trend


⚪ Session Handoffs
When one session hands to the next, watch how price behaves around the new session’s VWAP Bands after its anchor triggers. Continuation through the new VWAP vs. rejection often sets the tone.
