The Volume Price Trend (VPT) indicator helps traders determine a security’s price direction and the strength of its price movement by combining price trends with volume data.

It works by adding or subtracting a cumulative volume line based on the percentage change in price trends.

This indicator can help gauge the balance between a security’s demand and supply.

Understanding the Volume Price Trend Indicator

The VPT indicator calculates the cumulative volume by adding or subtracting volume based on the percentage change in price.

When the price rises, the indicator adds volume, and when the price falls, it subtracts volume.

This allows traders to understand both the direction of the price and the force behind the movement, based on the volume traded.

Trading With the Volume Price Trend Indicator

The VPT provides multiple trading signals that traders can use to make informed decisions:

  • Signal Line Crossovers: Traders may use a signal line (often a moving average of the VPT) to spot buying or selling opportunities. A buy signal occurs when the VPT line crosses above the signal line, while a sell signal is generated when the VPT line falls below the signal line.
  • Confirmations: Traders often use the VPT in conjunction with other indicators, such as moving averages and the Average Directional Index (ADX), to confirm trends. For example, a trader might buy a stock if the 20-day moving average is above the 50-day moving average, and the VPT is rising, indicating a strong upward trend.
  • Divergence: Traders look for divergences between the price action and the VPT line. A bullish divergence occurs when the price makes a lower low, but the VPT makes a higher low, signaling potential upward price movement. A bearish divergence happens when the price makes a higher high, but the VPT forms a lower high, suggesting a possible price decline.

Concluding Thoughts

The Volume Price Trend (VPT) indicator is a valuable tool for technical traders seeking to understand price momentum and confirm trends.

By combining price changes with volume, the VPT offers deeper insights into the strength of market movements. However, like all indicators, it works best when used alongside other technical tools to confirm signals and manage trading risks effectively.

The Money Flow Index (MFI) is a technical oscillator that combines both price and volume data to identify overbought or oversold conditions in an asset.

It can also detect divergences that signal potential trend reversals.

The MFI is unique because it incorporates volume into its calculations, making it different from other oscillators like the Relative Strength Index (RSI), which only considers price.

How to Calculate the Money Flow Index

  1. Calculate the typical price for each period.
  2. Determine if raw money flow is positive or negative by comparing the typical price of the current period with the previous period.
  3. Multiply the typical price by volume to calculate raw money flow.
  4. Add up positive and negative money flows over the past 14 periods to find the money flow ratio.
  5. Calculate the MFI using the money flow ratio.

What the Money Flow Index Tells You

  • Overbought and Oversold Signals: An MFI reading above 80 signals that an asset may be overbought, while a reading below 20 suggests it may be oversold. Traders may look for potential reversals after these signals.
  • Divergences: If the MFI moves in the opposite direction to the price, it may indicate a potential reversal. For instance, if the MFI declines while the price continues to rise, it could signal a bearish reversal.

Difference Between MFI and RSI

While the MFI incorporates volume into its calculation, the RSI only uses price data. This means that MFI might provide signals faster or more accurately in certain cases since volume is often viewed as a leading indicator.

Limitations of the MFI

  • False Signals: The MFI can generate false signals, indicating a potential trade that doesn’t result in the expected price movement.
  • Missed Signals: The MFI may not always indicate important market reversals, especially if divergences don’t appear.

Concluding Thoughts

The Money Flow Index (MFI) is a useful tool for traders looking to incorporate volume into their technical analysis.

By offering insights into overbought and oversold conditions, as well as potential divergences, the MFI can help traders spot trends and reversals.

However, like any indicator, it should be used in conjunction with other technical tools to reduce the risk of false signals and improve overall trading strategies.

The Chaikin Oscillator is a technical analysis tool created by Marc Chaikin.

It applies the MACD (Moving Average Convergence Divergence) methodology to the accumulation-distribution line rather than using the closing price.

This allows traders to evaluate the momentum of accumulation or distribution in the market.

Formula for the Chaikin Oscillator

CO=(3-day EMA of ADL)−(10-day EMA of ADL)CO = (3\text{-day EMA of ADL}) – (10\text{-day EMA of ADL})

Where:

  • ADL = Accumulation Distribution Line
  • EMA = Exponential Moving Average

How to Calculate the Chaikin Oscillator

  1. Calculate the Money Flow Multiplier: Determines the buying or selling pressure.
  2. Multiply the Money Flow Multiplier by volume: To get the Money Flow Volume.
  3. List a running total of the Money Flow Volume: To create the ADL.
  4. Compute the Chaikin Oscillator: Subtract the 10-day EMA from the 3-day EMA of the ADL.

Interpretation of the Chaikin Oscillator

  • A positive oscillator suggests increasing buying momentum (accumulation).
  • A negative oscillator suggests increasing selling momentum (distribution).

Example of Using the Chaikin Oscillator

A trader might use the Chaikin Oscillator to identify buy or sell signals:

  • A positive divergence occurs when the oscillator crosses above the accumulation-distribution line, signaling a potential buying opportunity.
  • A negative divergence occurs when the oscillator crosses below the line, signaling a selling opportunity.

Difference Between Chaikin Oscillator and Chaikin Money Flow

The Chaikin Money Flow (CMF) is a volume-weighted average of accumulation and distribution, while the Chaikin Oscillator measures the momentum of this accumulation or distribution.

Concluding Thoughts

The Chaikin Oscillator is a useful tool for technical traders, allowing them to evaluate the momentum of buying and selling pressure in the market.

When used in combination with other technical indicators, it can provide valuable insights into future market movements.

However, it’s essential to use the oscillator in conjunction with other tools to confirm signals and reduce the chances of false readings.

The Volume Rate of Change (V-ROC) is an indicator used to determine whether a volume trend is developing in either an upward or downward direction.

It allows traders and investors to gauge the speed at which the volume is changing over a specific period of time.

V-ROC is calculated by dividing the change in volume over a certain number of periods (such as days, weeks, or months) by the volume from n-periods ago, and the result is expressed as a percentage.

A positive V-ROC indicates that today’s volume is higher than it was n-periods ago, while a negative V-ROC indicates that volume is lower.

Volume and Price Movements

Over the last decade, the market has experienced large price swings, but not all of these moves have been supported by volume.

For chartists and technical analysts, the conviction behind a price move matters just as much as the price change itself.

Without sufficient volume, even a price movement of 5-10% in a stock can lack significance.

Conversely, in markets like the Nasdaq, where volume often exceeds two billion shares per day, any significant price action with strong volume draws analysts’ attention.

Volume Trend Indicator

V-ROC helps analysts determine whether a developing trend has sufficient volume to support it.

While it resembles price rate of change (which measures the rate of change in closing prices), V-ROC measures volume instead.

A shorter period, such as 10 to 15 days, may reveal sharp peaks in volume change, while a longer period of 25 to 30 days tends to produce smoother and more rounded charts.

This makes longer periods easier to analyze for identifying significant trends in volume.

Examples of V-ROC in Action

In the chart of the Nasdaq Composite Index, a 14-day V-ROC shows a significant spike on December 13, 2001, with a high of 249.00.

The V-ROC became positive on December 12, 2001, showing the potential for a market move after a decline in price that confused some investors.

However, when the V-ROC is analyzed using a 30-day period, it becomes clearer that the real positive volume trend doesn’t appear until January 3, 2002.

This longer period highlights more substantial price movement from 1987.06 to 2098.88, showing market support for the trend.

Analyzing Volume and Market Trends

The V-ROC, whether using a 14-day or 30-day period, often hovers above and below the zero line, indicating no strong trend.

In July 2002, a five-day price move occurred, which was not sustained due to the lack of volume, illustrating the importance of analyzing volume in conjunction with price action.

Later, in August 2002, the Nasdaq saw a price increase from 1206.01 to 1422.95, yet the V-ROC remained negative, signaling that the price move lacked conviction and was unlikely to hold.

Concluding Thoughts

V-ROC is a valuable tool for confirming price movements that have real market support.

By analyzing the volume behind price action, traders can avoid making decisions based on temporary market blips that are likely to be corrected.

It’s important to watch both volume and price trends to make informed investment choices.

On-balance volume (OBV) is a technical trading momentum indicator that uses volume flow to predict changes in stock price.

It was developed by Joseph Granville and introduced in his 1963 book Granville’s New Key to Stock Market Profits.

Granville believed that volume was the key force behind markets and designed OBV to predict major moves based on volume changes.

He described OBV as akin to “a spring being wound tightly,” where a sharp increase in volume without a significant price change would eventually lead to a price jump upward or downward.

Formula for On-Balance Volume (OBV)

The formula for OBV is:

OBV = Previous OBV + {volume, if the close is higher than the previous close, if the close is the same as the previous close −volume, if the close is lower than the previous close}

Where:

  • OBV is the current on-balance volume level.
  • Previous OBV is the OBV from the prior day.
  • Volume is the latest trading volume amount.

Calculating On-Balance Volume

OBV provides a running total of an asset’s trading volume, indicating whether the volume is flowing in or out of the security.

There are three rules for calculating OBV:

  1. If today’s closing price is higher than yesterday’s, the current OBV = Previous OBV + today’s volume.
  2. If today’s closing price is lower than yesterday’s, the current OBV = Previous OBV – today’s volume.
  3. If today’s closing price is equal to yesterday’s, the current OBV = Previous OBV.

What Does OBV Tell You?

OBV is based on the distinction between institutional investors (“smart money”) and less sophisticated retail investors.

When institutions start buying an asset, volume may increase even if the price remains stable.

Eventually, volume pushes the price upward as larger investors sell and smaller investors buy.

The OBV indicator itself is cumulative, and traders focus on its movement over time rather than its numerical value.

The slope of the OBV line is key for analysis, tracking volume numbers to signal potential opportunities for buying or selling.

Example of How to Use OBV

Consider a stock with 10 days of closing prices and volumes:

  • Day 1: Price = $10, Volume = 25,200 shares
  • Day 2: Price = $10.15, Volume = 30,000 shares
  • Day 3: Price = $10.17, Volume = 25,600 shares

On days where prices rise, volumes are added to the OBV, and on down days, volumes are subtracted.

The OBV values over the 10 days would be as follows:

  • Day 1 OBV = 0
  • Day 2 OBV = 30,000
  • Day 3 OBV = 55,600

OBV vs. Accumulation/Distribution

While OBV and the accumulation/distribution (Acc/Dist) line are both volume-based indicators, they differ in their calculation.

OBV adds or subtracts volume based on whether the price closed higher or lower.

Acc/Dist uses the position of the current price relative to its recent trading range, multiplied by the volume.

Limitations of OBV

  1. OBV is a leading indicator and can produce false signals due to its predictive nature.
  2. A large spike in volume on a single day (e.g., due to a surprise earnings announcement) can throw off the OBV for a long period.
  3. To reduce the likelihood of false signals, OBV is often used with lagging indicators such as moving averages.

Concluding Thoughts

On-balance volume (OBV) is a valuable technical indicator that measures volume flow to predict price direction.

While it offers insights into market sentiment and potential price movements, OBV should be used in conjunction with other indicators to confirm its signals and avoid false interpretations.

Balancing OBV with lagging indicators can provide a more comprehensive view for making informed trading decisions.
