◆ The PatternStandard deviation bands around VWAP: VWAP ± 1σ, 2σ, 3σ.
VWAP Bands — standard deviation envelopes around VWAP.
VWAP ± 1σ, ± 2σ, ± 3σ
where σ = standard deviation of (Price − VWAP) weighted by volume
where σ = standard deviation of (Price − VWAP) weighted by volume
Institutional levels:
• ±1σ → ~68% of trades → short-term mean reversion zone
• ±2σ → ~95% of trades → stretched, likely to snap back
• ±3σ → extreme → strong rubber-band effect
Day traders use these as dynamic support/resistance levels that adapt to volume distribution.

Pattern bridge: VWAP ± standard deviation bands combine weighted mean with dispersion. The same construction as batch norm’s mean-and-variance framing.
