The Mended Collective: London High/Low Killzones

50
This open-source indicator automatically tracks the London session (3 AM – 8 AM EST) on any intraday chart. It plots the session’s dynamic high and low, shades the active kill-zone, and labels the completed range so you can spot liquidity sweeps and breakout setups at a glance.

🔧 Features
  • Real-time session range
  • Detects the London window daily and updates the high/low as price evolves.


Visual highlights
• Color background during the active session
• Green line = London High | Red line = London Low
• Automatic labels once the session closes

Breakout alerts
Built-in alertcondition() triggers when price crosses above the London High or below the London Low, perfect for momentum or liquidity-grab strategies.

Time-zone aware
Uses New York (EST) timestamps so the range lines stay accurate on any broker feed.

🎯 How to Use
Add the indicator to any intraday chart (typically ≤ 1 h).

During 3 AM–8 AM EST the kill-zone is shaded; watch the evolving high/low.

After 8 AM EST the range is locked; trade retests, break-and-retest, or liquidity grabs with confidence.

Enable alerts to get notified the moment a breakout occurs.
