This indicator visually marks the London and New York trading sessions on your chart and optionally calculates the pip range (high-low movement) during each session. It's specifically designed for Forex traders, helping you identify volatility windows and analyze market movement within major session times.

Each marker is labeled clearly ("London Open", "NY Close", etc.)
Uses color-coding for easy identification:
Aqua for London
Lime for New York
✅ Pip Range Display (Optional)

Converts this movement into pips, using:

This feature can be toggled on/off via the settings panel.
