FIX connectivity | B3


The communication between B3's trading environment and its participants is carried out through several connectivity services, including TCP/IP limits, which use the EntryPoint protocol, based on the Financial Information eXchange (FIX) version 4.4.

  • FIX Order Entry sessions, for entry, order management and trading purposes;
  • FIX Drop Copy sessions, a report that summarizes a participant’s execution activity;
  • FIX Market Data sessions, for reception of real-time broadcast signal dissemination of stock and derivatives segments.
