Market Sessions

This script was inspired by Simple Market Session by tradergav.
I have improved and optimized it, making it compatible with Pine Script v6 and adding new features/enhancements.
All credit to the original author for the initial idea.

1. Purpose
The script highlights four major market sessions on your TradingView chart — Sydney, Tokyo, London, and New York. Each session is displayed as a colored background during its active hours.

2. How it Works
Default Times in UTC+1

• The script starts with fixed session times (in UTC+1 time).
  

Adjusting to Your Timezone

• You tell the script your own UTC offset. The script then shifts each session’s start/end time so they appear correctly in your local time on the chart.
  
• **For example, if you set your timezone to UTC+3, the script calculates the difference from its default base (UTC+1), which is +2 hours, and shifts all the session times by that amount.
  

In simple terms:
You pick your local timezone offset, and the indicator automatically shows when each of the four major sessions is open in your local time on your TradingView chart. That’s it!
