Volume-Weighted Moving Average (VWMA)

Price-volume weighted smooth trend line

Overview

VWMA is a moving average that weights prices by volume, placing greater emphasis on price levels where significant volume traded. Unlike simple moving averages, VWMA reflects where buying and selling interest was strongest.

Key Use: Identify true price support/resistance and smooth trend lines with volume confirmation.

Formula

VWMA = Σ(Close × Volume) / Σ(Volume)

For a specified period (typically 20, 50, or 200 periods)

Key Differences from SMA

Simple MA

All prices equal weight, regardless of volume.

VWMA

Prices weighted by volume - reflects true interest.

Use Cases

Trend Filters

Entry/Exit Points

Pullbacks to VWMA offer volume-weighted entries.
