Gap % (today)

WHAT THIS SCRIPT DOES

Gap % definition:
(9:30 RTH Open − Prior Day 4:00pm RTH Close) ÷ Prior Day 4:00pm RTH Close

How it achieves that (bulletproof):
✅ Pulls 1-minute data to avoid timeframe/session artifacts
✅ Uses the 15:59 1-minute bar close as the true 4:00pm close
✅ Uses the 9:30 bar open from the chart timeframe
✅ Computes the gap once
✅ Prints one label only, exactly at 9:30
✅ Rounds to whole % (stat-clean, journal-friendly)
✅ Visual placement is correct (yloc.abovebar)

This is institutionally clean.
