The Relative Vigour Index (RVI) is a technical analysis indicator designed to measure the conviction of the recent prevailing price action of an asset, as well as the possibility of its continuation in the short and medium-term.
The RVI indicator was developed by Donald Dorsey in 1993. The author then updated it into the current version in 1995. RVI belongs to the broad Oscillator group of indicators, which essentially means that it helps traders to determine overbought and oversold conditions in the market.
However, while most oscillators focus on the high and low prices (extremes) within a certain period, the RVI pays more attention to the closing price, relative to the opening price.
In addition to overbought and oversold signals, oscillators also tend to communicate whether a trend is gaining momentum or losing it. The inherent danger of using oscillators is that they can deliver false signals in the middle of strong trends, but this can sometimes be mitigated by combining them with other indicators. Some of the most common oscillators, other than RVI, include Stochastics, MACD, RSI (Relative Strength Indicator) and CCI (Commodity Channel Index).
The calculation of RVI is done in such a way that it is easy to determine the ‘vigour’ (or rather the energy) of the price at a particular close period.
The RVI’s formula for each period is as follows:
RVI = (Close – Open) / (High – Low)
- Close is the Closing Price
- Open is the Opening Price
- High is the Highest Price
- Low is the Lowest Price
The RVI has two lines: Green and Red. The Green line is the RVI itself, while the Red line is known as the ‘trigger’ or ‘signal’ line. The default setting of the RVI line is 10 periods, but this can be adjusted. The Red line is a 4-period moving average (volume-weighted) of the Green line, and it provides trading signals when it crosses above or below the RVI style line. Basically, like a moving average of the RVI, the Red line is more smoothed out and slightly lagging.
Reading the RVI Indicator
As an oscillator, RVI swings above and below a centreline. The RVI centreline is the 0 reading, which means that the indicator delivers both positive and negative readings. A positive reading implies that there is bullish momentum in the market, whereas a negative reading implies that there is bearish price momentum. Principally, when the RVI is around the centreline, it implies that price action is mainly neutral, with no discernible directional bias.
Extreme positive readings denote overbought conditions in the market, while extreme negative readings denote oversold conditions. At such readings, traders watch out for a cross of the signal line.
Trading RVI Signals
RVI delivers different types of trading signals as follows:
- Overbought and Oversold Conditions
These are the main types of signals RVI traders seek in the market. Depending on the parameters set, RVI will signal traders when there are potential overbought or oversold conditions in the market. Usually, a reading closer to 0.4 will imply overbought conditions, whereas a reading close to -0.4 will imply oversold conditions. When in overbought conditions, the idea is to look for opportunities to place a short sale order. The signal to sell will be when the Green line crosses the Red line downwards. Likewise, the idea is to place buy orders when RVI is in oversold conditions. The signal to buy will be when the Green line crosses the Red line upwards.
Divergences occur in the market when the price of an underlying asset moves contrary to indicator values. Divergences are a signal for price exhaustion in the market and usually serve as a precursor to potential trend reversals. There are straight and hidden divergences in the market. A straight bullish divergence will occur when the asset price is making lower lows, but the RVI makes higher lows. This will be a signal that the price lacks ‘vigour’ and traders will look to place buy orders in anticipation of an upward price reversal. Similarly, a bearish divergence will occur when the price is making higher highs, but the RVI makes lower highs. When a bearish divergence occurs, traders will look for opportunities to place sell orders in anticipation of a downward price reversal.
Hidden divergences are more common in trending markets. They help traders pick out optimal trade entry points when there is a retracement in the market. For instance, in a bull market, traders will look out for a bullish divergence when the price is making a pullback.
RVI Strategies with a Complimentary Indicator
Even Dorsey himself submitted that the RVI is not an independent technical analysis indicator; it is best suited as a complimentary one.
Here are the best indicators that work well with the RVI:
- RVI and Another Oscillator
Typically, oscillators work well in ranging markets. And two are better than one! RVI is naturally a leading indicator, and when ‘partnered’ with other oscillators, such as Stochastics or RSI, they can deliver definitive and high quality overbought and oversold trading signals.
- RVI and Two Moving Averages
Moving averages are known to smooth out price action in trending markets. However, when using two moving averages, a trend reversal can be confirmed when the faster-moving average crosses the slower one upwards or downwards, depending on the preceding trend. This can be a confirmation that a new trend has formed after an earlier signal was delivered by the RVI. For instance, in a bull market, the RVI can signal overbought conditions, but traders can begin to place sell orders in the market after the faster moving average has crossed the slower one, downwards. Overall, RVI is a versatile indicator that can help traders identify high-quality trading opportunities in the market consistently.

Main RVI Indicator & Strategies FAQ
What is the RVI Indicator?The Relative Vigor Index, or RVI Indicator, is a momentum indicator that provides a quantitative reading on the strength of price movement or trend. It gives a normalized reading on the strength behind trends in the market, helping traders determine when to enter or exit the market. The RVI is similar to the Stochastic Oscillator in that the RVI compares the high prices of the day, where the Stochastic Oscillator uses the low prices of the day. It is often used with other indicators to create maximum profits by trading in and out of an existing trend as the trend reaches peaks and retracements.
How do you use the RVI Indicator?The RVI indicator is displayed on a price chart below the prices and consists of two lines. The first line is the actual RVI Indicator, and the second line is a signal line, which is slightly delayed and more smoothed. The easiest points to watch are where these two lines cross each other, which signals a change in the market from bullish to bearish sentiment and vice-versa. Basically when the RVI line is on top the market is bullish, and when it is on the bottom the market is bearish.
What is the best RVI Indicator trading strategy?Combining the RVI Indicator with other indicators makes for a powerful combination. One of the popular combinations is the RVI with the RSI. When using this combination we would look for the RSI to become oversold (under a reading of 30) and then immediately go long when the RVI crosses above the signal line. Similarly we could wait for an overbought RSI (above a reading of 70) and immediately go short when the RVI crosses below the signal line.
