RVI Node
Relative Vigor Index - Price Action Oscillator
Overview
RVI (Relative Vigor Index) is a momentum oscillator that measures how often closing price is relative to opening price within a given period. Unlike indicators that look at absolute price movement, RVI focuses on intrabar structure - whether price is closing strong within its daily range. This makes RVI capture the essence of price action momentum without being affected by gap movements at open.
The insight behind RVI is simple but powerful: strong bullish candles are those closing near the top of their range, strong bearish candles are those closing near the bottom, and weak candles close near the middle. RVI quantifies this rigorous observation. Traders use RVI to identify true strength or weakness in price action, to confirm breakouts, and to detect divergences that reveal institutional accumulation or distribution at price extremes.
Formula
RVI measures close position within opening-closing range:
Signal = SMA of RVI (4 periods)
Close <strong>near middle</strong> of range = RVI near 0 (indecision)
Close <strong>near bottom</strong> of range = RVI near -1.0 (bears winning)
This price action ratio reveals true momentum independent of gap movements
RVI is unique because it ignores gaps completely. The opening is always the reference point. A stock that gaps up overnight then closes at yesterday's level will show negative RVI despite being higher overall. This price-action focus makes RVI excellent for identifying true intrabar strength regardless of gap changes or overnight news.
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| period | number | 14 | Lookback bars for RVI calculation. Standard 14 bars. |
| signal_period | number | 10 | SMA smoothing of RVI values for signal line. |
💡 Tip: RVI with 14-period default works best on daily timeframes. For intraday (4-hour and below), consider period=7 for faster response. The signal line(10-period) is mostly for visual clarity - most traders focus on RVI crosses above/below zero more than RVI-Signal crosses.
Common Use Cases
1. Breakout Confirmation - Is It Real Strength?
When price breaks out of a consolidation, RVI reveals whether it's backed by real strength or just a shake-out. A breakout above resistance where RVI is also above +0.5 = institutional conviction. A breakout where RVI barely moves = weak breakout likely to reverse. This price-action-based confirmation catches breakout traps before they fail.
2. Intrabar Strength Analysis for Scalpers
For scalping and short-term trading, RVI shows exactly which bars were strong (closed near top) vs weak (closed near bottom). Use this to identify which pullbacks within a trend were institutional traps (weak pullbacks with high RVI) vs genuine distribution (strong moves with low/negative RVI). Ideal for 1-hour intraday analysis.
3. Divergence Trading - Strength vs Price Divergence
RVI divergences are powerful because they show a mismatch between price action structure and price level. Price at new high but RVI negative/neutral = no institutional buying at top. Price at new low but RVI positive = institutional buying at bottom. These divergences reveal accumulation/distribution away from the price extremes.
4. Overbought/Oversold Definition - Know When Exhaustion Occurs
RVI above +0.6 = strong bullish price action (overbought). RVI below -0.6 = strong bearish price action (oversold). Unlike other indicators, RVI can't produce values beyond ±1.0, so extreme readings are mathematically bound. Use these extremes to time pullback entries into strong trends or reversals from extreme exhaustion.
Advantages & Limitations
Advantages
- •Focuses on price action structure (close vs open) not absolute levels
- •Unaffected by overnight gaps - pure intrabar strength measurement
- •Clear boundaries (max ±1.0) make overbought/oversold obvious
- •Excellent for confirming breakout quality and detecting traps
- •Works well on all timeframes with minimal parameter adjustment
- •Less known = less crowded signals in markets
Limitations
- •Less popular - few trading books cover it in depth
- •Requires real price data with opens and closes - gaps affect signals
- •Can whipsaw during choppy consolidations
- •Not ideal for gap-heavy assets (futures, commodities at open)
- •Works best with price action confirmation, not standalone
Tips & Best Practices
💡 Use RVI With Candle Patterns
RVI is at its best when used alongside price action/candle patterns. Strong bullish candle + high RVI = confirmation. Weak indecision candle + low RVI = confirms weakness. The combination of RVI numbers + candle appearance makes the strength assessment crystal clear.
📊 Trade from Extremes (±0.6)
Most reliable signals: RVI above +0.6 (strong trend in place) and RVI below -0.6 (weak trend in place). The middle zone (-0.6 to +0.6) is often choppy. Define clear thresholds for signal validity: only take entries when RVI crosses above +0.2 from below or shifts to clearly positive/negative zones.
⚡ Divergence = Institutional Levels
RVI divergences often form right at support/resistance where institutions accumulate or distribute. When you see price higher but RVI lower, look at the exact price level - it's often a key institutional zone. Trade the divergence expectation + volume confirmation = powerful reversal prediction.
⚠️ Avoid RVI Signal Line Crosses
While some traders use RVI-Signal crosses, these are slower and less reliable than RVI-zero crosses. Focus instead on RVI moving above/below zero and reaching extremes above +0.6 or below -0.6. Signal line is useful for visual smoothness only, not as a primary trading signal.
Example Strategy
Here's an RVI-based price action strategy:
RVI Breakout Quality Strategy
1Setup
- →Scan for consolidations with clear support/resistance levels
- →Apply RVI with defaults (14-period lookback)
- →Identify quality breakout setup: period of tight range + price consolidation
2Entry Signal (Long)
- →Breakout: Price breaks above resistance with strong candle
- →RVI Confirmation: RVI crosses above +0.4 (strength threshold)
- →Quality Check: Breakout candle close near top of range + high volume
- →Enter on next candle confirmation if RVI remains above +0.2
3Exit Signal
- →RVI drops below zero from above (momentum exhausted)
- →Or RVI falls below +0.2 after reaching +0.6+ (momentum rolling over)
- →Or divergence forms: price higher but RVI lower (distribution signal)
- →Stop loss: 1-2% below entry or at major support above entry
4Risk Management
- →Risk 1-1.5% of capital per trade (breakouts can fail)
- →Target 2:1 minimum reward-to-risk on breakout trades
- →Only trade breakouts with strong RVI confirmation (above +0.4)
- →Scale out 1/3 at 1R, trail remainder with RVI-based exit
