London ORB + Session High/Low + FVG

📘 Script Description: London ORB + Session High/Low + Fair Value Gap
This script is designed to assist intraday traders during the London session open by combining:

🕒 1. Opening Range Breakout (ORB)
Captures the high and low of the first 15-minute candle after the London open (08:00–08:15 GMT).

Draws lines and labels for the ORB High and Low levels.

Detects breakouts above or below the ORB and plots a triangle signal at the breakout bar.

🌐 2. Asian & US Session Levels
Automatically marks the highs and lows of the Asian (00:00–06:00 GMT) and US (13:30–20:00 GMT) sessions.

Useful for identifying prior session liquidity zones, key support/resistance levels, and potential reaction areas.

📉 3. Fair Value Gaps (FVG)
Highlights imbalances in price action between non-overlapping candles (also known as FVGs or inefficiencies).

Draws a shaded box between candles where gaps exist:

Green for bullish FVGs

Red for bearish FVGs

🔔 4. Alert Support
Optional alerts are built in for:

Long breakout (price breaks above ORB)

Short breakout (price breaks below ORB)

🎯 Use Case
Perfect for:

Day traders looking to capitalize on early volatility at the London open

Traders using liquidity-based strategies, retests, or gap-fills

Visualizing and aligning with prior session highs/lows for structure and context
