Oscillators: Relative Vigor Index (RVI)

The Relative Vigor Index (RVI) calculation is based on the idea that in a rising market the closing price is usually higher than the opening price, and in a bearish market the closing price is usually below the opening price.

To normalize the index the price fluctuation is divided by the maximum price range within the bar:

Relative Vigor Index (RVI) formula:



  • OPEN - open price;
  • HIGH - the highest price;
  • LOW - the lowest price;
  • CLOSE - close price.

To eliminate occasional price fluctuations (so called "noise") the Relative Vigor Index (RVI) oscillator is smoothed by the 10-period simple moving average. A signal line is also formed as a 4-period moving average on the oscillator values.

The basic signals of Relative Vigor Index (RVI) are:

  • Bullish divergence / bearish convergence - the main signal pointing to the weakness of the current trend;
  • A good moment to open a sell / buy position is the crossing of the RVI line by the signal line from above/below once the bullish divergence / bearish convergence has appeared on the chart;
  • In a flat market an exit from the overbought / oversold area is a signal to sell / buy.
