Release Notes
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.
Release Notes
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.
