Fix Notes – v1.1 "Timeframe Mismatch Resolved"When switching between intraday timeframes (e.g., 1m → 5m → 15m), the high-low box and labels shifted or misaligned. This issue arose from anchoring the box to bar_index, which varies by resolution.

Fix Notes – v1.2 "Chart Sterilization"All indicators and drawings have been removed to create a clean and minimal chart layout.
Some users mentioned the chart was hard to read, so I made it very sterile and stripped it down to the essentials, only the Previous Day High-Low Box remains.
This version fully complies with TradingView's publishing guidelines by focusing purely on the core indicator

Fix Notes – v2.0 "Pre-Market Box"Pre‑Market High/Low Box (04:00–09:30 ET by default)
- Tracks intraday pre‑market extremes and auto‑draws a box once pre‑market ends.
Color Options Split
- RTH and PM boxes now have their own fill/border color inputs to avoid confusion and allow easy theming.
Day Flip Resets
- Reset/deletion logic runs cleanly at each calendar day change, preventing boxes/labels from carrying over from the previous day.
