The OnixS directConnect: ITCH Market Data Handler SDKs provide ultra-low latency direct access to ITCH feeds via the ITCH Protocol.
Exchanges (Nasdaq, Nasdaq OMX, ASX, SGX, NZX, and Cboe BATS PITCH) use different application-level ITCH messages depending on the business context. At the same time, both the field data formats and the underlying session-level protocols usually remain the same.
The ITCH Handler uses highly optimized representations of ITCH message variations. It also includes implementations of widely used ITCH Feeds session-level protocols (e.g., MoldUDP64, SoupBinTCP).
