Delta_Volume_Dynamic&Fixed Range is an advanced volume profile indicator designed for day traders, scalpers, and swing traders utilizing Auction Market Theory. It provides institutional-grade analysis of volume distribution, value areas, and order flow dynamics. The indicator features a True Anchor Mode (Fixed Range) that allows users to place two vertical lines on the chart to lock the volume profile to a specific swing, session, or consolidation zone. This mode maintains profile stability regardless of zoom or scroll actions and supports historical backtesting by preserving anchor positions over extended timeframes.

An interactive on-chart UI panel enables quick toggling between dynamic Screen Mode and fixed Anchor Mode, profile position adjustments, visual customization, and switching between Buy/Sell Split and Delta Dominance volume coloring. The tool offers deep order flow insights, including visualization of aggressive buying versus selling, automatic detection of volume imbalances, and identification of High Volume Nodes (HVN) and Low Volume Nodes (LVN).

It displays dynamic Value Area High (VAH), Value Area Low (VAL), and Point of Control (POC) lines, with an option to extend naked POC lines as future support/resistance targets. Users can select data sources between tick data and 1-minute bars for optimized performance and historical analysis. The indicator is engineered for efficient rendering to handle large datasets without platform lag.
