Introduction
According to technical analysts, the Relative Volatility Index (RVI) serves as a tool for assessing the degree of volatility present in securities, commodities, or indices. It is a normalized oscillator designed to identify trends and potential reversals in asset price movements.
Developed by Donald Dorsey, a technical analyst and trader in the 1990s, the RVI was first introduced in his book, “The New Technical Trader: Boost Your Profit by Plugging into the Latest Indicators,” where he explained the theory behind the RVI and its practical use in trading analysis.
To calculate the RVI, traders divide an asset’s average true range (ATR) over a specified period by the standard deviation of the asset’s closing price over the same period. The resulting ratio is multiplied by 100 to produce a percentage value ranging from 0 to 100. A higher RVI value indicates higher volatility, while a lower RVI value indicates lower volatility.
Traders and analysts use the RVI to identify potential turning points in an asset’s price trend. When the RVI rises above a certain level, it may signal that the asset is becoming more volatile, and a trend reversal could be imminent. Conversely, when the RVI falls below a certain level, it may indicate that volatility is decreasing, and the current trend could be losing momentum.
Since its introduction, the RVI has become a popular tool among traders and analysts for measuring and analyzing volatility in financial markets. The RVI is often used in combination with other technical analysis tools, such as moving averages, to confirm or identify potential trading opportunities. However, traders should use the RVI in combination with other forms of analysis and risk management strategies to make informed trading decisions.

Computing the Relative Volatility Index
Traders can utilize the Relative Volatility Index (RVI) as a technical analysis tool for assessing the level of volatility of a particular asset. To calculate the RVI, traders use the following formula:
RVI = (10-period weighted moving average of standard deviation of closing prices) / (10-period weighted moving average of ATR)
The formula consists of three components: Average True Range (ATR), Standard Deviation, and Weighted Moving Average.
ATR measures the volatility of an asset by taking into account its price range over a specified period. It is calculated as the average of the true ranges for a given number of periods. The true range is determined by taking the largest of the following values:
- High minus Low,
- the absolute value of High minus previous close, and
- the absolute value of Low minus previous close
Standard deviation, on the other hand, measures the dispersion of a set of data from its mean. It provides an indication of how much the data points vary from the average.
A moving average is a calculation that smooths out price data by creating a constantly updated average price. In the RVI calculation, a weighted moving average is used to give more weight to recent data points.
To calculate the RVI, traders first need to calculate the 10-period weighted moving average of the standard deviation of closing prices and the 10-period weighted moving average of the ATR. Then, they divide the first value by the second value to get the RVI value.
It’s worth noting that the period used in the RVI calculation can be adjusted based on the trader’s preferences and the time frame being analyzed.
Understanding the Relative Volatility Index in technical analysis
A significant technical analysis tool for traders and analysts who specialize in volatility-based strategies is the Relative Volatility Index (RVI). The RVI has several benefits, including the following:
Measures volatility
The RVI is designed to measure the volatility of an asset, which can be valuable information for traders. By understanding the level of volatility, traders can adjust their risk management strategies and position sizing.
Identifies trend reversals
The RVI can help traders identify potential trend reversals in an asset. When the RVI rises above a certain level, it may indicate that volatility is increasing and that a trend reversal could be imminent. Conversely, when the RVI falls below a certain level, it may suggest that volatility is decreasing and that the current trend could be losing momentum.
Confirmation tool
The RVI can be used in combination with other technical indicators as a confirmation tool. For example, if a trader sees a bullish trend on a price chart and the RVI is also rising, it could provide confirmation of the upward trend and increase the trader’s confidence in the trade.
Customizable
The RVI is customizable, which means that traders can adjust the period length to suit their specific trading strategies and timeframes. This flexibility makes the RVI useful for traders with different trading styles and preferences.
Overall, the RVI is a valuable tool for technical analysts and traders who want to measure and analyze the volatility of an asset. It can provide insights into potential trend reversals and can be used in combination with other technical indicators to confirm trading signals.
Donald Dorsey’s suggestions on how to use the Relative Volatility Index
According to Donald Dorsey, the inventor of the Relative Volatility Index (RVI), traders can use the RVI in several ways to enhance their trading strategies. Here are a few key points to keep in mind:
Identify trend reversals
The RVI can help traders identify potential trend reversals by looking for divergences between the RVI and the price chart. For example, if the RVI is falling while the price of an asset is rising, it may indicate that the upward trend is losing momentum and that a reversal is likely.
Identify breakouts
The RVI can be used to identify potential breakouts by looking for sharp increases in volatility. When the RVI rises sharply, it could suggest that the asset is experiencing a significant increase in volatility, which may lead to a breakout above a key resistance level.
Trade divergences
Traders can also use divergences between the RVI and other technical indicators, such as the relative strength index (RSI), to enter or exit trades, depending on their trading strategy.
Customize period lengths
The period length used in the RVI calculation should be customized to suit the trader’s preferences and the time frame being analyzed.
Filter false signals
The RVI can be used as a filter to avoid false signals generated by other technical indicators. By waiting for the RVI to cross above a certain level before entering a long position, traders can confirm that the asset is experiencing increased volatility and that the upward trend is likely to continue.
Use in conjunction with other indicators
Traders can increase their confidence in their trading decisions and reduce the risk of false signals by using the RVI in combination with other technical indicators, such as moving averages or momentum indicators.
Use the RVI to set stop-loss orders
The RVI can be used to identify potential areas of support and resistance, which can be used to set stop-loss orders and manage risk.

Avoid over-reliance on the RVI
While the RVI can be a useful tool, it’s important not to rely solely on it. Traders should use the RVI in conjunction with other technical indicators, fundamental analysis, and risk management techniques to make informed trading decisions.
Manage risk
Dorsey emphasized the importance of risk management in trading and recommended using the RVI to identify potential areas of support and resistance, which can be used to set stop-loss orders and manage risk.
Overall, according to Donald Dorsey, the RVI is a valuable tool for traders who focus on volatility-based strategies. By using the RVI in combination with other technical indicators and risk management techniques, traders can make more informed trading decisions and improve their profitability.
Advantages & Limitations of the Relative Volatility Index
Here are some advantages and limitations of using the Relative Volatility Index (RVI) in trading:
Advantages
- Identifying potential trend reversals: By comparing the RVI with the price, traders can look for divergences to identify potential trend reversals. This can help traders enter or exit trades at the right time and improve their profitability.
- Filtering out false signals: The RVI can be used as a filter to avoid false signals generated by other technical indicators. By waiting for the RVI to confirm a signal before entering a trade, traders can improve their accuracy and reduce their risk.
- Identifying potential breakouts: When the RVI is rising sharply, it may indicate increased volatility, which could lead to a breakout above a key resistance level. By using the RVI to identify potential breakouts, traders can position themselves to take advantage of the resulting price movement.
- Customizable period length: The period length used in the RVI calculation can be customized to suit different trading styles and time frames. This makes the RVI a versatile tool that can be used in a variety of trading strategies.
Limitations
- False signals in ranging markets: In a ranging market, the RVI can generate false signals, as it may show an increase in volatility even though the price is not moving in a clear direction. This can lead to incorrect trading decisions and losses.
- Lagging indicator: The RVI is a lagging indicator, which means that it may not provide timely signals in fast-moving markets. Traders should use other technical indicators in conjunction with the RVI to confirm signals and reduce their risk.
- Not a standalone indicator: The RVI should not be used as a standalone indicator, as it only provides information about volatility and does not take into account other important factors such as market fundamentals, news events, or sentiment. Traders should use the RVI in conjunction with other technical indicators and fundamental analysis to make informed trading decisions.
- Sensitivity to market conditions: The RVI’s effectiveness can vary depending on the market conditions. For example, it may work well in trending markets but generate false signals in ranging markets. Traders should be aware of the market conditions and adjust their trading strategy accordingly.
The RVI is a technical indicator that traders can use to identify potential trend reversals, filter out false signals, and spot potential breakouts. By customizing the period length used in the RVI calculation, traders can apply this versatile tool in various trading strategies to improve accuracy and profitability.
Although the RVI is a useful tool for traders, it has limitations that should be considered. Due to its nature as a lagging indicator, it may not provide timely signals during fast-moving markets. It’s important to keep in mind that the RVI should not be relied upon as the sole indicator and that traders should supplement their analysis with other technical indicators and fundamental analysis to make informed trading decisions. As with any trading strategy, there is always a risk of loss, and traders should be aware of the potential risks and never risk more than they can afford to lose.
