Initial Balance is a technical indicator designed to track opening range structures across various timeframes, from intraday sessions to yearly cycles. It identifies the high and low price range established during customizable opening periods, including Daily, Weekly, Monthly, Quarterly, Yearly, and user-defined custom ranges. The indicator supports eight period types with timezone-aware session detection for major global markets such as Sydney, Tokyo, London, and New York.

Key features include configurable session start times with UTC offset adjustments, historical offset parameters for comparing past initial balance ranges, and multi-period analysis for trend confirmation. It offers optional Fibonacci retracement levels (11.4% to 88.6%) within the initial balance range to highlight mean reversion zones and precise entry or exit points. Additionally, Fibonacci projections extend upward or downward from the initial balance boundaries to indicate potential breakout targets and directional extension zones.

Line extension controls allow users to display the range during its formation, extend it to the current bar, or project it forward for planning purposes. The indicator ensures precise period detection, handling session overlaps and transitions accurately for global market analysis. This tool aids traders in identifying breakout, mean reversion, and volatility expectations based on opening range structures across all timeframes.
