Overview

RSTEmaVwap builds a daily VWAP from typical price and volume, then plots one- and two-standard-deviation bands around it on selected intraday charts. EMA lengths change by timeframe: short EMAs on three-, five-, and fifteen-minute charts, scaled longer EMAs on other intraday charts, and blended EMA-SMA lines on the daily chart. Three inputs hide the EMAs, the VWAP, or the deviation bands. It does not generate entries or exits.
