Relative Vigor Index Calculator
Calculate the published weighted Relative Vigor Index main line and four-value signal line from entered completed OHLC bars.
Enter a period and ordered OHLC bars
Use completed bars from one symbol, timeframe and broker feed.
One completed bar per line. Open and close must be inside the high-low range.

How Relative Vigor Index is calculated
Weighted down[i] = (H−L)[i] + 2(H−L)[i−1] + 2(H−L)[i−2] + (H−L)[i−3]
RVI[i] = Sum(Weighted up, N) ÷ Sum(Weighted down, N)
Signal[i] = [RVI[i] + 2RVI[i−1] + 2RVI[i−2] + RVI[i−3]] ÷ 6
Version 1.0.0 follows the standard MetaQuotes source weights 1, 2, 2 and 1. The main line begins at zero-based index N plus 2, and its signal begins three bars later at N plus 5.
The published source guard requires N plus 9 bars before calculation. If a rolling weighted-range sum is zero, the source returns the rolling numerator instead of dividing; this page preserves and discloses that convention.
Assumptions and limits
- At least period plus nine ordered OHLC bars are required; supported periods are 2 through 100.
- Rows must be oldest to newest and use one symbol, timeframe and feed.
- Open and close must be inside each entered high-low range.
- The zero weighted-range fallback returns the rolling numerator, following the published source.
- Main and signal values are displayed neutrally without crossover, direction, divergence or trade labels.
Worked example from the audited fixture
How to interpret the result
The main value is a ratio of rolling weighted close-open movement to rolling weighted range. The signal is a separate 1/2/2/1 average of reportable main values. Their difference is not classified as direction, divergence or a trade.
Frequently asked questions
- Enter a period from 2 through 100 and at least period plus nine ordered OHLC bars from one symbol, timeframe and feed.
- Current, prior, second-prior and third-prior close-minus-open values use weights 1, 2, 2 and 1.
- Current, prior, second-prior and third-prior high-minus-low ranges use the same weights 1, 2, 2 and 1.
- The rolling sum of N weighted close-open values is divided by the rolling sum of N weighted high-low values.
- The current and three prior main values use weights 1, 2, 2 and 1, then the total is divided by six.
- Version 1.0.0 returns the rolling numerator, matching the published standard source convention.
- Not necessarily. Feed history, entered starting point, symbol, timeframe and implementation history can affect the buffer.
- No. The page does not classify sign, crossovers, divergence, direction, entries or exits.
