OPEN-SOURCE SCRIPT

Are you tired of drawing random boxes on your chart that don’t actually correlate to price?
This indicator solves that. It’s a Session-Based Standard Deviation Percentage Calculator designed to show you where price has actually reacted—and where it’s statistically likely to react again.
Just select the session you’re trading as Session 1 and the previous session as Session -1. The script automatically builds a live data pool from those sessions, calculates the true standard-deviation-based percentage levels, and dynamically adjusts as new data comes in.
The result?
Clean, adaptive reversal zones grounded in real volatility, not guesswork—so you can finally stop drawing boxes and start trading price with precision.
