HL Boxes / OC Boxes (Taipei)

Oct 4

This indicator is a 4-hour rhythm tool tailored for the Taipei time zone, offering two independent modes: HL Boxes and OC Boxes (Pine v6).

What you’ll see

• 4H segment boxes: Instantly visualize the market structure of each 4-hour block.
  
• Today’s time anchors: “Today” is defined as 08:00 → next day 08:00 (Taipei). Price-scale values are shown only within this window to avoid leftovers.
  

Two modes

• HL Boxes: Builds a box from each 4H high/low. Optional opening dashed line (contrast-enhanced, extendable). Supports custom cross-session boxes (e.g., 21:30→04:00) with historical, day-by-day backfill.
  
• OC Boxes: Draws a box from each 4H open/close (close ≥ open = green; otherwise red). Includes time price lines (00/08/12/16/20): lines extend to the current bar, with a right-side {hh:mm} label. Optional display of these reference prices on the price scale. Also supports a custom time price line (e.g., 21:30), retained for 24h and auto-refreshing across days.
  

Best for

• Tracking 4H box ranges, breakouts, and retests.
  
• Intraday trading anchored to time references and cross-session comparison.
