Institutional Flow Radar is a trading indicator that identifies and classifies abnormal volume events on price charts into two categories: Capital (activity from stronger or more informed participants) and Public (activity from the broader crowd). It calculates a volume Z-score for each bar over a specified period and flags bars exceeding a set threshold as volume events. These events are further classified based on candle structure—smaller bodies with long wicks indicate Capital activity, while larger bodies with directional moves indicate Public activity.

The indicator visually marks these events by drawing horizontal levels at event prices, which remain until price moves decisively through them. Significant events are highlighted with colored bubbles indicating direction (bullish or bearish) and classification (Capital or Public). A P/L summary box aggregates volume at active levels, showing Capital and Public volumes currently in profit or loss.

Users can customize parameters such as the period for Z-score calculation, threshold for event detection, and visual settings including colors for bullish and bearish levels for both Capital and Public groups. This tool provides a consolidated view of where large volume occurred, which participant group is prevailing, and which price levels are holding, aiding in volume-based breakout analysis.
