VWMA − SMA+0.034volume concentrated on higher prices

VWMA = Σ(price × volume) ÷ Σ volume. When it sits above the plain SMA, the heaviest trading happened at higher prices — a sign that volume supports the up-move.

How to calculate a volume-weighted moving average

VWMA = Σ(Closeᵢ × Volumeᵢ) ÷ Σ Volumeᵢ (over n bars)

Paste prices oldest-first, one value or row per bar — straight from a spreadsheet or CSV export. Use “Sample data” to try it instantly.

Worked example

Two bars: close 10 on volume 1, close 20 on volume 3.
VWMA = (10 × 1 + 20 × 3) ÷ (1 + 3) = 17.5, versus an SMA of 15.

How to interpret a volume-weighted moving average

VWMA above the SMA means heavier volume occurred at higher prices — buyers backing the move. VWMA below the SMA in an uptrend suggests the rally is happening on light volume.
