Negative Volume Index (NVI) / Positive Volume Index (PVI)

Category: volume, momentum

A cumulative volume-based indicator that tracks price movements specifically during periods of decreasing volume (or increasing volume if Positive mode is active).

Formula

NVI_i = \begin{cases} NVI_{i-1} \times \frac{Close_i}{Close_{i-1}} & \text{if } Volume_i < Volume_{i-1} \\ NVI_{i-1} & \text{otherwise} \end{cases}

Inputs

• Shift (default: 0)
• InpTimeframe (default: PERIOD_CURRENT)
• Positive (default: false)
• VolumeType (default: VOLUME_TICK)
