History/Session VWAP Bands

Build me a session VWAP on NQ with ±1σ and ±2σ bands. Reset it at each session open.

Edited vwap_bands.ts — session VWAP, volume-weighted σ, two band pairs (lint clean)

Types clean

Compiled — 1 indicator, 5 plots

Ran on NQ! 15M — 126 bars, 0.4 ms per bar

Opened in split viewSession VWAP Bands

It's live in the preview: three sessions, each starting fresh at the open, with the VWAP line and both band pairs. σ is volume-weighted, so the bands widen when size comes in.

Settings you can tweak:

Session — RTH or the full Globex day (default RTH).
Band multipliers — 1 and 2 by default.
Source — typical price (hlc3), close, or ohlc4.

Want me to mark every touch of the +2σ band as a definition, so you can study what happens next?

What should change? — type @ for context
