Negative Volume Index Python API Documentation

The negative volume index (NVI) is often referred to as the `smart money indicator.` It works by the assumption that smart money (institutional money) is at work when volume decreases and vice versa when volume increases. NVI starts at 1000 and increases in regard to the percentage price change when volume decreases over a 255-day EMA period. Traders often use this technical indicator when researching broder markets and indices.
