What Is VWAP?

Volume-Weighted Average Price (VWAP) is a technical tool for daily analysis that calculates the average price of a security traded during the current trading day.

This indicator is updated at the beginning of each new trading session, taking into account the volume and price of traded shares. VWAP is a valuable metric for traders, providing a comprehensive view of the prevailing price trend and perceived value of a specific security

Understanding the Volume-Weighted Average Price

To calculate the Value-Weighted AP (VWAP), you first add up the total value of each trade by multiplying the price of each trade by the number of shares involved. Then, divide this total dollar amount by the total number of shares traded during the specified period. This can be represented by the following formula:

VWAP = (Sum of (Tick Price ×Tick Volume)) / Trading Volume

Please note that not every trader has access to the detailed data needed for this precise calculation.

Therefore, traders and chart providers often use a simplified formula that approximates the VWAP in real terms.

Charting software often uses a method to estimate the VWAP, typically using the following

formula:

VWAP = (Cumulative Typical Price x Volume) / Cumulative Volume

Where:

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

Cumulative = Total number of trades made since the beginning of the trading day

How to Calculate VWAP

When you place the VWAP indicator on a live chart, it calculates itself automatically. But if

you want to calculate it manually, here’s how:

Let’s assume you’re using a five-minute chart. The method remains the same no matter the

intraday timeframe.

First, calculate the average trading price of the stock during the first five-minute period of

the day. You can do this by adding the high, low, and closing price, then dividing the result by

three.

Multiply this average by the trading volume for that period. Place this result in a spreadsheet

in a column labeled “PV” (Price, Volume).

Next, divide the PV value by the trading volume for that same period. This gives you the

VWAP for that period.

To track VWAP throughout the trading day, continue adding the PV value from each new

period to the running total of previous PV values. Then, divide this total by the total trading

volume up to that point.

To simplify Step 3 in your spreadsheet, create columns for “Cumulative PV” and “Cumulative

Volume” and apply the formula to these totals

How Is VWAP Used?

Traders use the VWAP indicator in a variety of strategies. They may use it to confirm current

trends and establish specific trading guidelines based on it.

For example, some traders may view stocks trading below the VWAP indicator as potentially

undervalued, while those trading above it may be viewed as overvalued. If a stock price

moves from below to above the VWAP, traders may initiate long positions. Conversely, a

price decline from above to below the VWAP may prompt traders to sell their holdings or

open short positions.

Institutional investors, such as mutual funds, use the VWAP indicator to execute large stock

trades with minimal disruption to the market price. Therefore, institutions often aim to buy

stocks below or sell above the VWAP. This strategy helps their trades pull the price toward

the average, rather than away from it

VWAP vs. Simple Moving Average

While the VWAP and SMA (simple moving average) may appear visually similar on a chart,

their underlying calculations differ significantly, resulting in different representations.

VWAP is determined by multiplying the typical price by the corresponding trading volume,

then dividing the sum of these values by the total trading volume.

In contrast, the SMA considers price data but not volume. The SMA is calculated by summing

the closing prices over a specified period of time (for example, a 10-day period), then

dividing this sum by the number of periods (for example, 10).

Limitations of VWAP

The VWAP indicator operates daily and is reset at the beginning of each trading day.

Attempting to average VWAP over multiple days may lead to inaccurate and

misleading results.

• Although some institutional traders may use the VWAP indicator as a signal to buy

when prices are low and sell when prices are high, it is important to remember that

the VWAP indicator alone is not a comprehensive trading strategy.

In strong uptrends, prices can maintain upward momentum for extended periods

without a sustained decline below VWAP, or only a brief decline. Therefore, relying

solely on a price decline below VWAP may miss out on potential gains during a rapid

price surge.

• The VWAP indicator is based on past price data and does not inherently predict

future price movements. Because the VWAP indicator is tied to the daily opening

price range, the indicator’s lag increases as the trading day progresses.

This is evident when comparing a 1-minute VWAP after 330 minutes (a typical trading

session) with a 390-minute moving average at the end of the day, as they often show

a similar pattern

Why Is the Volume-Weighted Average Price Important?

The VWAP provides traders with a volume-weighted average price, smoothing out price

fluctuations over a specific period of time. Furthermore, institutional traders use it to

prevent large trades from significantly impacting the price of the asset they are trading.

For example, a hedge fund might choose not to place a buy order at a price above the VWAP

of a security to avoid artificially inflating its value. Similarly, they might avoid placing sell

orders at a price significantly below the VWAP to prevent an unnecessary price decrease

Is VWAP a Leading Indicator?

Contrary to some beliefs, the VWAP indicator is not a leading indicator, but rather a lagging

indicator. Its calculation is based on past price and volume information. It does not include

any current data. Therefore, its usefulness is limited and is not useful for traders who require

the very latest market information

Can VWAP Be Used for All Types of Stocks and Markets?

Because it calculates price averages using real-time trading information, VWAP is most

reliable in markets with high liquidity and high volume, such as large-cap stock markets and

major market indices.

The VWAP indicator’s accuracy declines in stocks with low trading volume, as sudden price

and volume fluctuations can distort its calculations. Furthermore, its daily reset reduces its

usefulness in day trading, making it less effective in analysing long-term trends.

In conclusion, the Volume Weighted Average Price (VWAP) indicator is an effective tool for

traders, especially institutional investors, as it provides a valuable perspective on a security’s

average price throughout the trading day. This volume-based indicator provides a more

accurate reflection of market activity than simple moving averages and helps large traders

execute their orders without significantly impacting the price.

However, it is important to understand the limitations of the VWAP indicator. It is a lagging

indicator and not a predictor of future price movements. It is most effective in highly liquid

markets and should be used in conjunction with other technical analysis tools and trading

strategies.

Relying on the VWAP indicator alone can lead to missed opportunities and potential losses.

However, by understanding its calculations, applications, and limitations, traders can

leverage this indicator to make more informed trading decisions and navigate the

complexities of the market. Remember that successful trading requires a comprehensive

approach, and the VWAP indicator is best used as part of a larger strategy.
