I have a script based on VWAP. Now VWAP starts at session beginning and is unreliable for first 2 15-minute candles. Since the script is based on VWAP, I need the script to record values only after say 9:45 AM i.e. disregard the first 2 15-minutes candles (Since market opening is at 9:15 in India. Also find my code below. Please suggest ways to get the desired results.
