Key features

The OnixS directConnect: Nasdaq NFI ITCH Market Data Handler SDK supports the Nasdaq NFI ITCH 3.0 Market Data feed with GLMPSE 3.0 order-book snapshot support. The Nasdaq Fixed Income (NFI) ITCH data feed uses a MoldUDP64 transport containing data describing all public orders and trades that occur on the Nasdaq Fixed Income (NFI) US Treasury alternative trading system (ATS). The GLIMPSE 3.0 order-book snapshot feed is supported in this SDK implementation and complements the ITCH 3.0 feed and uses the same message formats encoded using SoupBinTCP 3.0.
