The Negative Volume Index (NVI) is a cumulative indicator that uses the change in volume to decide when the smart money is active.
Paul Dysart first developed this indicator in the 1930s. In fact, the Market Technicians Association selected Dysart for their annual award in 1990 to recognize his contributions to technical analysis.
Dysart's Negative Volume Index works under the assumption that the smart money is active on days when volume decreases and the not-so-smart money is active on days when volume increases.
Returns the handles of a technical indicator, in case of failure returns an empty string.
