Direct Answer
Price Volume Trend is a volume measure used to measure participation, traded volume, volume-weighted price, or volume-at-price structure. The production page must define the exact calculation convention before interpreting higher or lower readings, because platform and provider implementations can differ.
Price Volume Trend: Formula, Meaning, Signals, Examples and How to Use It
How Is Price Volume Trend Calculated?
Price Volume Trend (PVT) is a cumulative indicator that adds or subtracts volume in proportion to the percentage price change each bar. Unlike On-Balance Volume, a small price move adds only a small fraction of the bar's volume.
Formula: PVT = prior PVT + Volume x (Close - prior Close) / prior Close
Inputs:
- Bar closes
- Bar volumes
- Starting PVT value (usually zero)
Worked example. With a prior PVT of 15,000 and a bar closing at 102 from 100 on 400,000 shares, the new PVT is 23,000. The inputs are illustrative numbers, not market data.
Reading it. A rising PVT with rising prices indicates volume is backing the advance, and a falling PVT with falling prices indicates volume is backing the decline. Divergence between PVT and price is read as a sign the trend is less supported.
Limits. The absolute level depends on the starting value and the date the series begins, so only its direction and its divergence from price matter. Large percentage moves on low volume and small moves on high volume get very different weights.

What is Price Volume Trend?
Price Volume Trend is a volume measure used to measure participation, traded volume, volume-weighted price, or volume-at-price structure. The production page must define the exact calculation convention before interpreting higher or lower readings, because platform and provider implementations can differ.
For Swoopr, the canonical profile separates definition, calculation, interpretation and decision use. That keeps readers from collapsing a descriptive metric into a trading strategy. An indicator can describe trend, momentum, volatility, participation, positioning or risk without providing a complete entry, exit, sizing or portfolio decision.
What does it measure?
Price Volume Trend measures specific market properties in the Volume domain. The practical value is repeatability: the same inputs and formula can be applied across a defined dataset, allowing users to compare readings through time or across instruments when the calculation convention is held constant.
How to read Price Volume Trend
Interpretation depends on the market property being measured. A descriptive reading is not automatically predictive. The same numerical state can lead to different outcomes in a strong trend, quiet range, event-driven gap or illiquid market. Always combine with context from price structure, volume, and broader market regime before drawing conclusions.
Strengths
- Weighting volume by the percentage price change makes small moves count as small, which separates it from OBV's all-or-nothing signs.
- A running total keeps all history, so divergences between price and the cumulative line can be inspected over long spans.
- Reproducible when the formula and data convention are fixed.
Weaknesses and limitations
- Every bar adds to the total, including very small moves, so many tiny price changes can accumulate into a drift that looks like a trend.
- A bad price tick produces a large percentage change multiplied by volume, which is added permanently to the cumulative line.
- Correlated indicators can create false confidence by repeating the same underlying information.

Frequently Asked Questions
Is Price Volume Trend a buy or sell signal?
No. A rising PVT with rising prices indicates volume is backing the advance, and a falling PVT with falling prices indicates volume is backing the decline. The absolute level depends on the starting value and the date the series begins, so only its direction and its divergence from price matter. A trade built on it still needs a trigger, an invalidation rule, a position size and realistic execution assumptions.
What is the best setting for Price Volume Trend?
Price Volume Trend takes these inputs: bar closes; bar volumes; starting PVT value (usually zero). There is no universal best setting for the tunable ones, so test them across instruments, regimes and out-of-sample periods and favor stable parameter regions over one historical winner.
Can Price Volume Trend be used by itself?
The absolute level depends on the starting value and the date the series begins, so only its direction and its divergence from price matter. Large percentage moves on low volume and small moves on high volume get very different weights. For that reason it is read next to measures of direction, participation, valuation, liquidity and risk, not alone.
Does Price Volume Trend work on every timeframe?
The calculation (PVT = prior PVT + Volume x (Close - prior Close) / prior Close) can be run on any bar size, but behavior is not portable: a reading on a five-minute chart describes a very different market window from the same reading on a daily chart. Validate the exact timeframe before relying on it.
Why does Price Volume Trend give false signals?
Every bar adds to the total, including very small moves, so many tiny price changes can accumulate into a drift that looks like a trend. A bad price tick produces a large percentage change multiplied by volume, which is added permanently to the cumulative line. Lag, noise and regime changes add to this, because market participants react to new information after the reading is calculated.
How should Price Volume Trend be backtested?
Rebuild Price Volume Trend from bar closes using point-in-time data, write the rules before testing, include delisted securities where relevant, model realistic fills and costs, reserve a validation sample and compare with a simpler baseline.
