Buyer and Seller VWAP

This indicator calculates and visualizes Buyer and Seller Volume-Weighted Average Prices (VWAP) using a Least Squares Moving Average (LSMA) smoothing method. It classifies trades based on candle direction—buys when the close is above or equal to the open, and sells when the close is below the open.

The indicator applies LSMA to both buyer and seller VWAP values to reveal underlying trends with reduced noise. It also calculates a standard deviation band around each LSMA line, creating a shaded zone that represents volatility. This helps traders identify periods of expansion, contraction, and potential breakout opportunities based on buyer/seller strength.
