Dual Volume Divergence Index [DW]

2017년 12월 11일

This is an experimental variation of Paul L. Dysart's Positive Volume Index and Negative Volume Index that tracks the divergences between the PVI and its EMA, and the NVI and its EMA, then plots both together for comparison.

This tool can be used to identify trending price activity.

Updates:
Added optional smoothing to the script using an exponential moving average to filter noisy outputs.

Added a mode selection with three modes to choose from:
- Dual Index Mode, which displays the original DVDI
- Oscillator Mode, which displays the difference between the PVDI and NVDI as a centered oscillator
- Bar Counter Mode, which displays the number of bars in which volume divergence is in a positive dominant phase and negative dominant phase
