Key Takeaways

  • RVI compares closing prices relative to opening prices and the trading range to measure trend conviction
  • Signal line crossovers generate buy and sell signals similar to MACD
  • Works best in trending markets as a confirmation tool
  • The indicator is based on the principle that closings are stronger in uptrends and weaker in downtrends

What Is Relative Vigor Index (RVI)?

The Relative Vigor Index (RVI) is a momentum oscillator based on the principle that prices tend to close higher than they open during uptrends and lower than they open during downtrends. The indicator measures the "vigor" or energy behind price movements by comparing the close-open relationship to the high-low range, then smoothing the result with a moving average. The formula involves calculating the ratio of the close-to-open difference divided by the high-to-low range, with additional smoothing using a 4-period symmetrically weighted moving average. RVI generates signals through centerline crossovers (above/below zero) and signal line crossovers (RVI crossing its signal line). The indicator works best in trending markets where the closing price consistently relates to the direction of the trend. It is often used as a confirmation tool alongside other indicators rather than a standalone signal generator.

Relative Vigor Index (RVI) Example

  • 1When RVI crosses above its signal line while both are below zero, it suggests bearish momentum is weakening and a potential reversal is forming.
  • 2A rising RVI above zero during an uptrend confirms that closes are consistently strong relative to the trading range.
