Ratio S/R - Intraday Support & Resistance Levels

Introduction

This script identifies key intraday support and resistance (S/R) levels where price tends to reverse frequently. It is designed specifically for intraday trading and aims to help traders find high-probability reversal zones.

The logic behind the script revolves around logarithmic returns, historical volatility, and ratio-based price levels. The script dynamically calculates price ranges using standard deviation-based volatility and applies preset ratio levels to determine potential support and resistance zones.

How It Works
Dynamic Range Calculation

The script calculates the price range based on the previous day’s logarithmic return volatility.

The range is then used to project different levels of price movement.

Reference Price

You can choose whether the reference price is from today’s open or yesterday’s close (oporcl setting).

This helps adapt the levels based on market behavior.

Ratio-Based Levels

The script applies specific ratios to the calculated range:

• 0.0833 (Minor Reversal Zone)
  
• 0.25 & 0.38 (Primary Reversal Zones)
  
• 0.62 & 0.75 (Significant Reversal Zones)
  
• 1.0 & 1.25 (Extreme Reversal Zones)
  

These levels act as potential support and resistance points.
