Look at the picture, here, NVI (Negative Volume Index) rises on days of the positive price change on lower volume. On the other side, NVI falls on days of the negative price change on lower volume. Besides this, NVI is unchanged on days of higher volume no matter what the price action moves.

NVI Buy Sell

Here, comes the 2nd strategy. As you know, the red line is a 255-period simple moving average. When the index line crosses the MA line from below and goes above it, the bullish trend is coming forward. Hence, you can buy or take entry from the crossing level. The exact opposite scenario happens during a bearish trend. When the index line cross the MA and goes below it, sellers can take entry there.

Bearish Divergence Chart

The next strategy is Divergence. Divergence happens when price and index direction does not match with one another. Like the above picture, when price makes higher highs but the indicator makes a lower low, the price is going to slow down.

Key Points

  • The NVI combines both price inputs as well as volume to form an indicator of when so-called smart and not-so-smart money is active.
  • Generally, markets moving off high volume are virtually ignored by the NVI indicator.
  • The indicator should not be traded in isolation. All indicators should be used in other methods of technical analysis.
  • The Negative Volume Index measures volume on the points that the volume is less than the previous point.


The Negative Volume Index is a hybrid indicator. It combines inputs from Paul Dysart and Norman Fosback. They designed this indicator for broad market indices and exchange volume. In the Negative Volume Index, the counts’ price changes when volume decreases and discounts price changes when the volume increases. Traders can use this technical indicator on stocks and ETFs, but NVI does not always act as expected. The Negative Volume Index will produce some great bullish/bearish divergence signals with some stocks. Traders should not take decisions only on the basis of NVI, as with all indicators.
