Parameters:

  • Source: The data source for the calculation.
    • Open Price: Uses the opening price of each period.
    • High Price: Uses the highest price of each period.
    • Low Price: Uses the lowest price of each period.
    • Close Price: Uses the closing price of each period.
    • Volume: Uses the trading volume of each period.
    • Weighted: A weighted price is typically calculated as (High + Low + Close + Close) / 4.
    • Typical: Calculated as (High + Low + Close) / 3.
    • Median: Calculated as (High + Low) / 2.

The Price Volume Trend (PVT) is a technical analysis indicator that combines both price and volume to determine the power of a price trend and its potential continuation or reversal. It is similar in concept to the On-Balance-Volume (OBV) indicator but offers a more nuanced approach by considering the percentage change in price.

How PVT Works: The PVT indicator accumulates volume in proportion to the price change over time, providing insight into money flow into and out of a security. The basic premise is that significant price movements accompanied by high volume indicate stronger trends, while movements with low volume may not be sustainable.

Formula for PVT: The Price Volume Trend is calculated as follows:

PVT = Previous PVT + (Close - Previous Close) / Previous Close * Volume

Here’s a breakdown of the components:

  • Previous PVT: The PVT value from the last period.
  • Close: The closing price of the current period.
  • Previous Close: The closing price of the last period.
  • Volume: The volume of the current period.

Key Aspects of PVT:

  1. Trend Confirmation: The PVT helps confirm the underlying trend. If the PVT is rising along with prices, it suggests that the uptrend is strong and likely to continue. Conversely, if the PVT falls while prices rise, it may indicate weakening momentum and a potential reversal.
  2. Divergence: Divergence between PVT and price can signal potential reversals. For example, if prices are making new highs but the PVT is not, it could suggest that the upward momentum is weakening, which might precede a price decline.
  3. Volume Weighting: By factoring in the percentage change in price, the PVT accounts for the relative significance of volume. Larger price moves on higher volume significantly impact the PVT, making it a more sensitive measure of trend strength than other volume indicators.

Application of PVT:

  • Identifying Buy and Sell Signals: Traders look for divergences between PVT and price to identify buy or sell signals. A positive divergence, where the PVT rises while prices fall, can indicate a potential buying opportunity. Conversely, a negative divergence, where the PVT falls while prices rise, may signal a selling opportunity.
  • Trend Analysis: By observing the direction of the PVT, traders can confirm the strength and sustainability of the current trend. A steadily rising PVT in an uptrend suggests strong buying pressure, while a declining PVT in a downtrend indicates strong selling pressure.
  • Volume Confirmation: PVT can be used to confirm volume patterns. For instance, if a breakout occurs with a corresponding rise in PVT, it suggests that the breakout is supported by strong volume and is likely to be valid.

Advantages of PVT:

  • Sensitivity to Price Changes: PVT’s incorporation of percentage price changes makes it more responsive to significant price movements than other volume indicators like OBV.
  • Early Signals: Due to its sensitivity, PVT can provide early signals of trend reversals, giving traders a potentially valuable heads-up before other indicators confirm the change.

Limitations of PVT:

  • False Signals: PVT can produce false signals like all technical indicators, especially in choppy or sideways markets.
  • Lagging Nature: While PVT can give early signals, it is still a lagging indicator and may not always predict future price movements accurately.
  • Complexity in Calculation: The PVT calculation is more complex than simpler volume indicators, which might be a drawback for some traders.

Conclusion: The Price Volume Trend (PVT) is a valuable tool for traders looking to gauge the strength of a trend by considering both price and volume. By focusing on the percentage change in price relative to volume, PVT offers a more detailed view of market dynamics than some other volume-based indicators. PVT can help traders make more informed decisions about trend strength, potential reversals, and entry or exit points when used with other technical analysis tools and indicators. However, as with any indicator, it is essential to use PVT as part of a broader analytical framework to mitigate the risks of false signals and to enhance overall trading strategy effectiveness.
