Release Notes
Bug Fix: The previous version was computing session highs/lows directly on the chart timeframe. On higher TFs, each bar spans a wider time window — a 4H bar's high/low includes prices outside the session boundaries, so you get different values when you switch timeframes.

The script now computes all session highs/lows on the 1-minute timeframe via request.security(), and then uses those consistent values for box drawing on any chart TF.
