Introduction
The Volume Rate of Change (VROC) is a technical analysis tool that helps measure how quickly a stock’s trading volume is changing over a set time. It’s like a scanner for spotting shifts in how much a stock is being bought and sold, which can give us clues about where its price might go.
The VROC indicator is notable for its absence of a specific individual or entity credited with its inception. It embodies a more generic concept employed to gauge the pace of change in trading volume over a defined period. With time, traders and analysts have devised their own tailored iterations of this indicator to align with their unique requirements and trading methodologies. Fundamentally, VROC emerges as a collaborative product of accumulated knowledge and experience within the sphere of technical analysis, rather than the brainchild of a solitary individual or institution.
Here’s how it works: VROC looks at the difference between how much a stock is traded now and how much it was traded “n” periods ago (you can pick how many periods “n” represents, depending on your trading style). Short-term traders may use a shorter period (e.g., 5 days), while long-term investors might use a longer period (e.g., 21 or 50 days). If VROC is positive, it means the current trading is higher than “n” periods ago, suggesting more buying or selling activity. If it’s negative, it means there’s less trading activity.
When VROC is strongly positive, it can mean a lot of people are buying the stock, possibly driving the price up. On the flip side, a strongly negative VROC can suggest many people are selling, which might push the price down. Traders also watch for differences between VROC and the stock’s price. For instance, if prices are going up while VROC is dropping, it might mean less interest in buying, hinting at a possible price reversal.
In a nutshell, the Volume Rate of Change is a tool that helps us see how trading activity is changing over time. It’s quite handy for understanding market sentiment and predicting price movements, especially when combined with other analysis methods.

Computing the Volume Rate of Change Indicator
The Volume Rate of Change (VROC) indicator is a straightforward tool used to measure how much trading volume has changed over a specific time frame. It tells us whether there has been an increase or decrease in trading activity. To calculate VROC, you can use the following formula:
VROC = [(Current Volume - Volume "n" periods ago) / Volume "n" periods ago] * 100
Here’s what each part of the formula means:
- Current Volume: This is the trading volume for the current period, such as the volume for today.
- Volume “n” periods ago: This is the trading volume for the same security “n” periods in the past. The value of “n” depends on your choice; it could be 1 day ago or 20 days ago, depending on your strategy.
Let’s break down how to calculate VROC step by step:
1. Decide how many periods (“n”) you want to use for your calculation. This choice depends on your trading or analysis strategy. For example, if you’re looking at daily charts, you might use a 1-day or 20-day VROC.
2. Find the trading volume for the current period (e.g., today) and for the period “n” days ago. If you’re looking at weekly data, “n” weeks ago; if it’s daily data, “n” days ago.
3. Plug these values into the formula.
4. Calculate the result. The VROC value you get represents the percentage change in volume over the chosen time period. A positive value means there’s been an increase in volume, while a negative value means volume has decreased compared to “n” periods ago.
VROC is a valuable tool for traders and analysts because it helps them understand how quickly trading activity is changing. This, in turn, can offer insights into potential shifts in market sentiment and price movements.
Remember, the choice of “n” depends on your trading strategy and the time frame you’re analyzing. Short-term traders might prefer a 1-day or 5-day VROC, while long-term investors might use a 21-day or 50-day VROC to capture longer-term trends in volume.
Understanding the Volume Rate of Change Indicator in technical analysis
The Volume Rate of Change (VROC) indicator holds significance in technical analysis for several reasons, primarily related to its interpretation and the insights it offers regarding trading volume and potential price movements:
Measuring Volume Momentum
VROC quantifies the rate of change in trading volume over a specified period. This metric indicates whether trading volume is increasing or decreasing relative to historical data. This information is crucial because alterations in trading volume often precede price fluctuations. A surge in volume can signify growing interest and momentum in a security.
Confirmation of Price Trends
VROC can be employed to confirm or contrast with price trends. When the price is ascending, and VROC is also positive, it suggests that the upward price trend is supported by increased buying interest. Conversely, if prices are climbing while VROC is diminishing, it may imply a weakening trend.
Identifying Potential Reversals
A notable divergence between price and VROC can at times indicate potential trend reversals. For instance, if prices are reaching new highs, but VROC is declining, it might suggest that buying momentum is diminishing, potentially signaling an impending reversal.
Volume Patterns
VROC aids in recognizing specific volume patterns. For example, a sudden spike in volume accompanied by a significant rise in VROC might indicate a potential breakout or a robust price movement.
Confirmation of Breakouts
When a price breakout occurs, traders often seek confirmation from volume. If a breakout is accompanied by a surge in volume and a positive VROC, it can be perceived as a more robust and dependable signal.
Risk Assessment
VROC assists in evaluating the risk associated with a trade. A substantial increase in volume and VROC can indicate heightened volatility and potentially increased risk. Conversely, declining volume and VROC can suggest reduced risk or a lack of conviction in the market.
Cross-Asset Analysis
VROC is utilized not only for individual securities but also for broader market analysis. By examining volume changes across various assets or sectors, analysts can glean insights into market sentiment and potential shifts in market dynamics.
Combining with Other Indicators
VROC is frequently employed in conjunction with other technical indicators such as moving averages, or relative strength to bolster trading decisions and provide additional confirmation.
In summary, the Volume Rate of Change indicator is a valuable tool in technical analysis as it offers insights into the dynamics of trading volume, a pivotal factor in comprehending market sentiment and potential price movements. It empowers traders to make more informed decisions by confirming trends, identifying possible reversals, and assessing risk. Nonetheless, like any technical indicator, it should be used alongside other analytical tools to obtain a comprehensive view of market conditions.
How to use the Volume Rate of Change in trading?
We suggest using the Volume Rate of Change (VROC) indicator in a methodical and disciplined manner to enhance your trading decisions. Here is a practical guide on effectively employing VROC in your trading:
Select Your Timeframe
Start by choosing a timeframe that suits your trading style. Day traders may prefer shorter timeframes like 1-hour or 15-minute VROC, while swing traders might opt for daily or weekly VROC.
Determine ‘n’ Period
Decide the number of periods (‘n’) that align with your strategy and the asset you are trading. The appropriate value for ‘n’ depends on asset volatility and your preferred trading horizon. Common values include 1, 10, 21, or 50 periods.
Combine VROC with Price Analysis
VROC is most effective when used alongside price analysis. Seek confirmations or discrepancies between VROC and price movements. For instance, if you consider a long trade and notice both rising prices and a positive, increasing VROC, it strengthens the case for an uptrend.
Spot Divergences
Pay close attention to divergences between VROC and price. If prices are reaching new highs while VROC is declining or turning negative, it may indicate a weakening trend and potential reversal.
Identify Breakouts
Use VROC to identify potential breakout opportunities. When a price breakout occurs, check for confirmation from VROC. A breakout with increased volume and a positive VROC can be a strong signal.
Confirm Reversals
When VROC starts diverging from the prevailing trend, it may signal a trend reversal. However, always confirm reversals using other technical indicators or price patterns.
Incorporate Risk Management
Integrate VROC into your risk management strategy. Consider VROC values when setting stop-loss orders or determining position sizes. Higher VROC values may necessitate wider stop-losses due to higher volatility.

Combine with Other Indicators
Don’t rely solely on VROC. Use it alongside other technical indicators like moving averages, RSI, MACD, or trendlines for a comprehensive analysis.
Backtesting and Continuous Learning
Before implementing VROC in live trading, test it on historical data to understand its effectiveness in various market conditions. Continuously learn and adapt, as market conditions change.
Exercise Discipline
Stick to your trading plan and strategy. Avoid impulsive decisions solely based on VROC signals. Combine VROC with a broader trading plan that includes entry and exit criteria.
Remember, no single indicator guarantees success, and trading always carries risks. VROC is a valuable tool, but it should be part of a comprehensive trading approach that considers multiple factors and risk management principles. Lastly, exercise patience and avoid overtrading; not every VROC signal will lead to a profitable trade.
Advantages & Limitations of the Volume Rate of Change Indicator
Here are some advantages and limitations of using the Volume Rate of Change (VROC) indicator in trading:
Advantages
- Volume Confirmation: VROC (Volume Rate of Change) provides a clear, numerical way to assess changes in trading volume. It helps validate the strength or weakness of price trends. When price movements align with rising volume, it boosts traders’ confidence in the trend’s credibility.
- Early Warning Signals: VROC can give early indications of potential shifts or reversals in market trends. When VROC differs from price movements, it can serve as a warning that market sentiment might be changing, enabling traders to prepare for possible reversals.
- Customizability: VROC is highly adaptable. Traders can tweak the number of periods and the timeframe to match their specific trading strategy and the assets they’re dealing with. This adaptability allows traders to tailor the indicator to different market conditions.
Limitations
- False Signals: Like many technical indicators, VROC can produce false signals, especially during times of low trading activity or when markets are being manipulated. Relying solely on VROC, without confirmation from other indicators or analysis, can lead to inaccurate trading decisions.
- Lagging Indicator: VROC is considered a lagging indicator because it relies on historical volume data. It may not always offer timely signals in fast-moving markets or for intraday trading. Traders need to be aware of this lag and utilize other tools for precise entry and exit points.
- Interpretation Variability: Interpreting VROC can be subjective. There is no universally agreed-upon threshold for what constitutes a strong or weak VROC signal. Traders may interpret the same VROC data differently, potentially leading to varying trading decisions.
VROC can be a valuable asset in a trader’s arsenal, providing insights into changes in trading volume and their potential influence on price movements. However, for effective use, it should be employed in conjunction with other indicators and analytical techniques to validate signals and manage its limitations adeptly.
The VROC indicator serves as a valuable tool for traders aiming to understand how changes in trading volume influence price movements. It offers several benefits, such as confirming trends, giving early warning signs, and allowing customization. When used thoughtfully alongside other analysis methods, VROC can enrich traders’ comprehension of market dynamics and potentially enhance their trading decisions.
It’s crucial to emphasize that although the VROC indicator can be a helpful part of a trading strategy, it is not a guaranteed predictor of market behavior. Trading inherently involves risks, and VROC, like any technical indicator, has its limitations. These limitations encompass the possibility of false signals and delayed responses. Traders should exercise caution, implement risk management strategies, and view VROC as one tool in their trading toolkit. Furthermore, past performance should not be considered a reliable indicator of future results, and traders must conduct thorough research and analysis before making any trading choices.
