Relative Vigor Index: the close-minus-open move compared with the bar range over 10 bars, with a signal line.
Overview
The Relative Vigor Index (RVGI) compares where bars close relative to where they open, in its own pane. In up moves, closes tend to be above opens; in down moves, below.
It shows an RVGI line in green and a signal line in red.
How it works
Numerator = (close - open) smoothed with weights 1, 2, 2, 1 over four bars. Denominator = (high - low) smoothed the same way. RVGI = sum of numerators / sum of denominators over 10 bars.
Signal = RVGI smoothed with the same 1, 2, 2, 1 weights.
How to use it
- Some traders watch RVGI crossing its signal line.
- Use readings above zero as a sign closes are beating opens.
- Look for divergence with price.
- Pair it with a trend tool for context.
These are ways some traders read it, for learning. They are not trade signals.

- It reacts quickly and can cross often in ranges.
