RVI: Relative Vigor Index

Measures whether candles tend to close near their highs (vigour up) or their lows (vigour down).

הרעיון במילים פשוטות

In healthy uptrends prices tend to close higher than they open; in downtrends lower. RVI compares the close-minus-open with the high-minus-low over recent candles.

איך זה מחושב

A smoothed close − open divided by a smoothed high − low, averaged over 10 candles; the signal line is a short weighted average of RVI.

Num = weighted (close − open) of the last 4 candles (weights 1, 2, 2, 1, ÷ 6)
Den = weighted (high − low) of the last 4 candles
RVI = SMA(Num, 10) ÷ SMA(Den, 10)
Signal = (RVI + 2×RVI₁ + 2×RVI₂ + RVI₃) ÷ 6

איך משתמשים בזה

  • RVI crossing above its signal line: momentum turning up; below: turning down.
  • Divergences with the price warn of reversals.

הסקת מסקנות

  • Best combined with the trend: buy crossovers in uptrends.

דוגמה

After a slide, RVI crosses above its signal line while the price makes a slightly lower low: a bullish divergence.
