Feeds
Description
Aggregates (Per Minute)
Stream minute-by-minute aggregated OHLC (Open, High, Low, Close) and volume data for a specified cryptocurrency pair via WebSocket. These aggregates update continuously in Coordinated Universal Time (UTC). If no trades occur within a given minute, no bar is emitted, transparently indicating a period without trading activity. This endpoint provides a live feed of aggregated bars, enabling users to monitor intraday price movements, refine trading strategies, and power real-time crypto market visualizations. Use Cases: Real-time monitoring, dynamic charting, intraday strategy development, market research.
WS/crypto/XA
Aggregates (Per Second)
Stream second-by-second aggregated OHLC (Open, High, Low, Close) and volume data for a specified cryptocurrency pair via WebSocket. These aggregates update continuously in Coordinated Universal Time (UTC). If no trades occur within a given minute, no bar is emitted, transparently indicating a period without trading activity. This endpoint provides a live feed of aggregated bars, enabling users to monitor intraday price movements, refine trading strategies, and power real-time crypto market visualizations. Use Cases: Real-time monitoring, dynamic charting, intraday strategy development, market research.

Market Hours and Timezone

Unlike traditional markets, cryptocurrency trading operates continuously, 24 hours a day, 7 days a week, across multiple global exchanges. This around-the-clock activity enables you to engage with markets at any time, from anywhere.

All crypto data is standardized to Coordinated Universal Time (UTC). This global alignment simplifies time-sensitive analytics, ensuring consistent data integration and interpretation, regardless of your geographic location or the exchanges you track.

Infrastructure and Reliability

Our WebSocket infrastructure is engineered to handle the decentralized, high-volume nature of cryptocurrency trading. We connect directly to multiple leading exchanges, ensuring minimal latency and maximum data integrity. Redundant systems, load balancing, and scalable architecture enable stable, low-latency data delivery even during periods of heightened market activity.

This robust framework supports latency-sensitive applications, such as automated trading bots, real-time order book visualizations, and high-frequency analytical models.

Data Flow: From Exchanges to You

Cryptocurrency data originates from numerous global exchanges, each with its own market structure and liquidity. At Massive, we source data directly from major venues including Coinbase, Bitfinex, Bitstamp, and Kraken. Binance was previously included but has not been an active source since 2021. We regularly review and update our exchange coverage to ensure transparency and data accuracy.

We aggregate this exchange data, normalize differing formats, and stream a unified dataset over WebSockets. As soon as trades occur, quotes shift, or order book levels update, this information is relayed directly to your subscribed channels—keeping your systems aligned with live market conditions.
