Directional Volume Index

A new idea of mine that I am presently experimenting on for my trades.

The Directional Volume Index (DVI) is defined as follows:
DVI = VWMA(len1) - SMA(len2), where by default, len1==len2

The sign of the DVI provides volume confirmation of the direction of the price trend.
The magnitude of the DVI provides the volume confirmation of the strength of the price trend.

This indicator and script is free for the TV community to use.
