Stream second-by-second aggregated OHLC (Open, High, Low, Close) and volume data for specified tickers via WebSocket. These aggregates are updated continuously in Eastern Time (ET) and cover pre-market, regular, and after-hours sessions. Each bar is constructed solely from qualifying trades that meet specific conditions; if no eligible trades occur within a given minute, no bar is emitted. By providing a steady flow of aggregate bars, this endpoint enables users to track intraday price movements, refine trading strategies, and power live data visualizations.
Use Cases: Real-time monitoring, dynamic charting, intraday strategy development, automated trading.
