Example Indicator: 3 Sessions Indicator [Nexo Mechanics]

This indicator is a demo script inspired by the Forex 3-Session System. It visualises three major market sessions (Tokyo, London, New York) on-chart and shows a simple world clock.

What it demonstrates

• How to detect sessions in different time zones and draw session boxes that update with the session high/low.
  
• Optional Tokyo split into AM and PM blocks.
  
• A compact World Clock table (London, New York, Tokyo) with local time and OPEN/CLOSED status.
  
• Basic session open alerts (London, New York, Tokyo, Tokyo PM).
  

Notes

• Sessions are intentionally limited to up to 60m charts for clarity/performance.
  
• Some timeframes can show slightly misaligned boundaries if they don’t divide evenly into an hour.
  
• Published for demo purposes. Not a robust or tested trading system.
