Opening range structure across any period—intraday sessions to yearly cycles—with Fibonacci levels and extension projections.

Marks High/Low range established during opening periods (Daily, Weekly, Monthly, Quarterly, Yearly, or Custom Range) as reference for breakouts, mean reversion, and volatility expectations.

Eight period types with timezone-aware session detection (Sydney/Tokyo/London/NY), historical offset for multi-period comparison, optional seven Fibonacci levels (11.4% to 88.6%) inside IB range, upward/downward projections from boundaries, flexible line extension control (IB period only, current bar, or N periods forward), and precision period detection deliver comprehensive opening range analysis for traders targeting structure-based setups across all timeframes.
