The most powerful APIs for normalized market data
Learn more ->
Same API for real-time and historical data
Our live API uses the same interfaces and data structures as our historical market replay, letting you use the same code for backtest and live trading.
Entire venue in a single subscription
Subscribe to every update of every symbol on the venue, in a single API call—like a direct feed—be it over internet or cross-connect.
Tick-by-tick with full order book depth
All buy and sell orders at every price level. Get each trade, every tick, and order queue composition at all prices.
Nanosecond, PTP-synchronized timestamps
The only normalized market data solution to provide up to four timestamps for every event, with sub-microsecond accuracy across venues.
Low latency
The fastest real-time feed over public cloud. 90th percentile latency up to your application at 42 microseconds (cross-connect) or 590 microseconds (internet).
Seamless intraday replay
Join your real-time subscription with a seamless, streaming replay of the session. All within the ease of a single API call.
Multiple connectivity options
Get the full feed wherever you are. Cross-connects in NY4 and Aurora. Dedicated interconnect to AWS, GCP, Azure, and 8 PoPs.
Engineered for low latency and high precision
Colocation
Layer 1 switches
PTP
FPGAs
Rust
Zero-copy
Kernel bypass
Redundancy
Our servers are situated in primary colocation facilities like Equinix NY4 and CyrusOne Aurora I, and to minimize hops to the matching engine. This reduces latency and makes our timestamps more deterministic.
