BubbleXRay is a volume-based trading indicator designed for the cTrader platform that visualizes institutional order flow through proportional volume bubbles directly on price charts. It highlights high-volume spikes as bubbles sized according to volume magnitude, enabling traders to identify where significant market participants are active. The indicator integrates Cumulative Volume Delta (CVD) data to distinguish buying versus selling pressure, providing deeper insight into volume dynamics without cluttering the chart. Key features include instant detection of volume spikes upon bar close, auto-scaling via a rolling percentile window adaptable to trending or ranging markets, and price-anchored volume display rather than separate histograms. Additional functionalities include dual confirmation using radial rings and overlay arrows for enhanced CVD context, zero-configuration automatic timeframe selection, and customizable opacity and display limits for a clean user interface. The indicator supports analysis of key market structure concepts such as key levels, liquidity sweeps, imbalances, supply and demand zones, and support/resistance. A preset example configuration is provided for Gold (XAUUSD) on a 1-minute chart. A tutorial video is available to assist users in setup and application. BubbleXRay requires volume and tick data and outputs visual signals directly on price charts.
