RSRCH: DC-VWMA Width Calc

// Research intention of this script
// Objective : to find the direction of movement of index indicators
// Methodology : take the Donchian and VWMA input
// Compute Donchian and VWMA
// find the total width of Donchian = upper donchian value - lower donchian value
// Find the upper segment = upper donchian value - VWMA value
// find the lower segment = VWMA value - lower donchian value
// Plot them to see the trends glaringly.
// This works best with linebreak or Hiekin Ashi
