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.
B3 offers three types of FIX Sessions to access its trading and market data platforms (trade-related data):
- 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.
