It was generated by John F. Ehlers. 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 on the bearish market the closing is usually below the opening price.
The basic signals of Relative Vigor Index (RVI) are:
1- Bullish divergence / bearish convergence - the main signal pointing to the weakness of the current trend.
2- 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.
3- In a flat market an exit from the overbought / oversold area is a signal to sell / buy.
