PVT: Price Volume Trend
A running total of volume, added or subtracted in proportion to each candle's percentage change.
L’idée en termes simples
Like On Balance Volume, PVT asks whether volume flows into rises or falls, but it weighs each candle's volume by how far the price actually moved.
Mode de calcul
Each candle adds volume × (close − previous close) ÷ previous close to the running total.
PVT = PVT₋₁ + volume × (close − close₋₁) ÷ close₋₁Comment l’utiliser
- Rising PVT confirms an uptrend; falling PVT confirms a downtrend.
- Divergences warn that a trend lacks support.
Tirer des conclusions
- The absolute level means nothing; the direction and divergences do.
Exemple
MSFT daily: the price makes a new high but PVT does not; the rally has less volume behind it than the last one.
Les prix des exemples sont donnés à titre d’illustration.
Points de vigilance
- Tick volume on CFDs approximates real volume.
