Bank Holiday Bug Fix🛠️ Bug Fix: ORB Extension During Market Holidays
Problem: When a bank holiday occurred during trading hours, the ORB would fail to properly terminate at the designated extension end time (e.g., 11:00 EST). This caused the ORB from the previous session to continue extending indefinitely, even into the next trading day, resulting in overlapping ORBs and visual clutter on the chart.
Root Cause: The extension end time fell within the holiday's market closure window, so the indicator never received a bar to trigger the justPassedExtendTime() function. When trading resumed (often at 6:00 PM EST for futures), the previous day's ORB remained active and continued extending.
✅ What's Fixed
Calendar Day Detection - The ORB now tracks the full date (day, month, year) and automatically terminates if it detects a new calendar day has begun without the extension properly ending.
Maximum Bar Limit - Added a new safety parameter "Max Extension Bars" (default: 500) that forces the ORB to close if it extends beyond a reasonable number of bars, preventing runaway extensions in any edge case.
Improved Session Detection - Enhanced the new session detection logic to properly handle overnight gaps and market reopenings after holidays.
