About
FourBlock - IVB (Initial Volume Breakout) An evolved multi-session Opening Range Breakout (ORB) framework designed to capture institutional volume and project key statistical expansion levels. Key Levels and Calculations: Range = IVB High - IVB Low IVB High / Low = Session opening range extremes IB_M (50%) = (IVB High + IVB Low) / 2 Protection (62%) = IVB High + (0.62 * Range) and IVB Low - (0.62 * Range) Ext Avg (150%) = IVB High + (1.50 * Range) and IVB Low - (1.50 * Range) Ext 1-dev (300%) = IVB High + (3.00 * Range) and IVB Low - (3.00 * Range) Ext 2-dev (600%) = IVB High + (6.00 * Range) and IVB Low - (6.00 * Range) Ext 3-dev (900%) = IVB High + (9.00 * Range) and IVB Low - (9.00 * Range) Main Features: - Real-Time IVB Line: IVB High and Low start drawing immediately at Session Open and update dynamically without overlapping lines. - Smart Staged Display: Only IVB High and Low show during formation. Extension levels appear automatically once the range finishes. - Range Gap Highlight: Clean background shading between IVB High and Low (default: ON). - 4 Major Sessions (UTC): Sydney (21:00), Tokyo (00:00), London (07:00), and New York (13:00) with fully customizable open times. - Flexible Durations: 15m, 30m, 60m, or Custom minutes. - Performance Optimized: Built-in history limit (Past Sessions to Keep) to prevent chart lag. - Customizable Visuals: Colors per session, line styles (Solid, Dashed, Dotted), line widths, and price labels.
