NVI(close; volume; initialValue)

The first two arguments must be arrays: 'close' contains the close values, 'volume' contains the volumes.

The 'initialValue' parameter is the initial value for the Negative Volume index.

The result is an array.

The Negative Volume Index is used in conjunction with the Positive Volume Index to identify bull markets. The Negative Volume Index changes only when the volume decreases from the previous day.
