The Negative Volume Index tracks price changes exclusively on days when volume decreases, based on the theory that smart money operates during quieter trading sessions. NVI is a long-term tool primarily used in stock markets to detect institutional accumulation. Pair it with the PVI for a complete picture and browse our indicator guide library for additional volume analysis tools.
When today's volume is less than yesterday's: NVI = previous NVI + (percentage price change × previous NVI). When volume increases, NVI stays unchanged. A 255-day EMA is typically overlaid as a signal line. NVI rising on falling volume suggests informed buyers are quietly accumulating.
The Volume Weighted Moving Average weighs each price bar by its volume before averaging, so high-volume bars have more influence on the average than low-volume bars. VWMA gives traders a truer picture of the "agreed-upon" price compared to a standard <a href="/academy/indicators/simple-moving-average" class="text-primary hover:underline">SMA</a>. It is especially useful in <a href="/market/stocks" class="text-primary hover:underline">stock</a> and <a href="/market/crypto" class="text-primary hover:underline">crypto</a> trading on <a href="/tools/platforms/tradingview" class="text-primary hover:underline">TradingView</a>, and can be explored alongside other volume tools in our <a href="/academy/indicators" class="text-primary hover:underline">indicator guide library</a>.
On-Balance Volume tracks cumulative buying and selling pressure by adding volume on up days and subtracting volume on down days — it often leads price breakouts by showing institutional accumulation or distribution. OBV divergence is one of the strongest early-warning signals available, especially when confirming <a href="/guides/trade-breakouts" class="text-primary hover:underline">breakout setups</a> in <a href="/market/stocks" class="text-primary hover:underline">stocks</a> and <a href="/market/crypto" class="text-primary hover:underline">crypto</a>. Pair OBV with the <a href="/academy/indicators/volume-profile" class="text-primary hover:underline">Volume Profile</a> for a complete picture of where institutional money is flowing.

The Chaikin Oscillator applies the <a href="/academy/indicators/macd" class="text-primary hover:underline">MACD</a> formula to the <a href="/academy/indicators/accumulation-distribution" class="text-primary hover:underline">Accumulation/Distribution</a> line, producing a momentum reading of money flow that leads price turns. It is particularly useful for validating breakout strength in <a href="/market/stocks" class="text-primary hover:underline">stocks</a> and spotting divergence before significant moves in <a href="/market/crypto" class="text-primary hover:underline">crypto</a>. Browse our <a href="/academy/indicators" class="text-primary hover:underline">indicator guide library</a> to pair the Chaikin Oscillator with trend-following tools.
