v1.80 — DST-Aware Historical Timezone Engine
Previous versions applied the current day's GMT offset uniformly to all historical bars, causing session boxes and the institutional candle to shift by one hour for approximately six months of history whenever the chart was viewed across a DST boundary. v1.80 replaces this with a per-day timezone engine that mathematically computes the correct broker GMT offset for every individual calendar date scanned — covering EU DST (last Sunday March/October) and US DST (2nd Sunday March / 1st Sunday November) via a new DST Rule input. Auto-detection now correctly derives the stable winter base offset rather than the raw current offset. The info panel displays live DST status (Active/Standard time). All session boxes, levels, and institutional candle markings are now historically accurate regardless of when the chart is viewed.
