VWMA with Highlighted Zones

This script plots a Volume-Weighted Moving Average (VWMA) on a price chart and highlights buy and sell zones based on price positioning relative to the VWMA. It first calculates the VWMA using a user-defined length and source price. If the closing price is below the VWMA, the script marks the area between the low and the VWMA as a buy zone, coloring it red. If the closing price is above the VWMA, it marks the area between the high and the VWMA as a sell zone, coloring it green. These highlighted regions help traders visually identify potential support and resistance areas based on volume-weighted price movements.
