Negative Volume Index (NVI)
Cumulative index that starts at 1000 and follows price changes only on falling-volume days, on the premise that "smart money" positions itself quietly while crowded high-volume days are noise. Traditionally read against its own one-year moving average rather than a fixed threshold.
