Hidden Gem

417
Hidden Gem plots the 2:00–6:00 AM (New York) range as a single "CRT candle" and projects its High, Low, and 50% midpoint through the trading day.

WHAT IT DOES
• Tracks the high and low of every bar between 2:00 and 6:00 AM New York time — the 4-hour candle that spans the late Asia / London open.
• Draws the CRT High, CRT Low, and the 50% midpoint (dashed), with live price labels.
• Extends those levels through the session (default until 5:00 PM) so you can see how price reacts to them during London and New York.
• Optionally shades the 2–6 AM range and marks "sweeps": a candle that wicks beyond the CRT High or Low but closes back inside the range.

HOW TO USE IT
This is a Candle Range Theory (CRT) tool. Common ways traders use these levels:
• A sweep of the CRT High that closes back inside can signal a move toward the 50% or the CRT Low (and the reverse for a sweep of the Low).
• The 50% midpoint often acts as a decision level / partial-profit area.
• Combine with your own confirmation (structure shift, candle pattern, higher-timeframe bias). The levels are context, not signals on their own.

SETTINGS
• CRT window (default 0200-0600) and extend window (default 0600-1700), with selectable timezone.
• Days to keep on chart.
• Color: Auto (black on light charts, white on dark charts), Black, or White.
• Line width, midpoint style, range shading, label size.
• Optional sweep markers.

ALERTS
• CRT high swept (wick above, close back inside)
• CRT low swept (wick below, close back inside)
• Price crossed the CRT 50% midpoint

NOTES
• Works on timeframes 4H and below. Extended hours (ETH) must be enabled, since the window is overnight.
• Designed for CME futures such as MGC/GC, but works on any symbol that trades during these hours.
• Levels are calculated from completed price data within the window and do not repaint after 6:00 AM.
