Understanding the Volume Weighted Average Price (VWAP)

The Volume Weighted Average Price (VWAP) is a popular technical indicator used to provide a measure of the average price a security has traded at throughout the day, based on both volume and price. It is commonly used by traders to assess the market trend and determine the average price of a security over a specific period.

What is the Volume Weighted Average Price (VWAP)?

VWAP calculates the average price of a security, weighted by the volume traded at each price level. This means that the VWAP gives more importance to prices where more trading activity occurs, providing a more accurate representation of the average price paid by traders over a given period.

How is the VWAP Calculated?

VWAP is calculated using the following steps:

1. Calculate the Typical Price:

   • The typical price is the average of the high, low, and close prices for the period.

   Typical Price = (High + Low + Close) / 3

2. Calculate the Cumulative Total:

   • Multiply the typical price by the volume for each period to get the cumulative total of volume-weighted prices.

   Cumulative Total = Σ(Typical Price * Volume)

3. Calculate the Cumulative Volume:

   • Sum the volume for each period to get the cumulative volume.

   Cumulative Volume = Σ(Volume)

4. Compute the VWAP:

   • Divide the cumulative total by the cumulative volume to get the VWAP.

   VWAP = Cumulative Total / Cumulative Volume

Formula

The formula for VWAP is:

VWAP = (Σ(Typical Price * Volume)) / (Σ(Volume))

Where:

• Typical Price is the average of the high, low, and close prices.
• Volume is the trading volume for the period.
• Σ denotes the summation over the specified period.

Example Calculation:

Assuming the following parameters:

• Data Offset (pod): 1
• Data Type (data): cv (close volume)
• Period: 10

1. Calculate the typical price for each period.
2. Multiply the typical price by the volume for each period.
3. Sum these values to get the cumulative total.
4. Sum the volumes over the period to get the cumulative volume.
5. Divide the cumulative total by the cumulative volume to obtain the VWAP.

Uses of the Volume Weighted Average Price (VWAP)

VWAP is utilized for various purposes in trading and market analysis:

1. Trend Confirmation

VWAP helps confirm trends by indicating the average price at which the security has traded throughout the day. A price above the VWAP suggests an uptrend, while a price below indicates a downtrend.

2. Trade Execution

VWAP is often used by institutional traders to execute large orders. Trading near the VWAP helps ensure that orders are executed at a fair average price, avoiding market impact.

3. Support and Resistance Levels

VWAP can act as a dynamic support or resistance level. Traders may use it to identify potential reversal points or areas of interest for trade entries and exits.

Parameters

Here are the parameters used to configure VWAP:

• Data Offset (positionOfData):

  • Default Value: 1
  • Min Value: 1
  • Max Value: 300
  • Description: Specifies the number of data points to use. A value of 1 means using the most recent data, while 300 means looking back 300 data points.

• Data Type (data):

  • Default Value: cv
  • Description: Defines the type of data for VWAP calculation. Options include close volume, which represents the combined use of closing prices and trading volumes.

Advantages of the Volume Weighted Average Price (VWAP)

• Accurate Average Price: Reflects the average price based on volume, offering a realistic view of the security’s trading price.
• Trend Confirmation: Helps in confirming trends by comparing the current price with the VWAP.
• Trade Efficiency: Useful for executing large trades at an average price to minimize market impact.

Limitations of the Volume Weighted Average Price (VWAP)

• Intraday Only: VWAP is typically used for intraday trading and may not be relevant for longer-term analysis.
• Not a Forecast Tool: VWAP is a lagging indicator and does not predict future price movements.

Conclusion

The Volume Weighted Average Price (VWAP) is a valuable tool for traders seeking to understand the average trading price of a security throughout the day. By incorporating both price and volume into the calculation, VWAP provides a more nuanced view of market trends and helps traders make informed decisions. Whether you’re executing large trades or analyzing market trends, VWAP can be an essential component of your trading strategy.
