RVI: Relative Vigor Index
Measures whether candles tend to close near their highs (vigour up) or their lows (vigour down).
الفكرة بكلمات بسيطة
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.
طريقة الحساب
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) ÷ 6كيفية الاستخدام
- RVI crossing above its signal line: momentum turning up; below: turning down.
- Divergences with the price warn of reversals.
استخلاص النتائج
- Best combined with the trend: buy crossovers in uptrends.
مثال
After a slide, RVI crosses above its signal line while the price makes a slightly lower low: a bullish divergence.
