New version of the Derivatives market binary market data protocol
Dear MOEX Derivatives Market clients,
A new version of the SIMBA SPECTRA (ex. SBE FOL) protocol is available for testing on the T1 test environment.
Change list:
- The protocol has been renamed to SIMBA SPECTRA.
- The 'package' attribute in the protocol schema has been changed to "simba_spectra".
- Off-book clearing trades and IOC order misses are not published anymore.
- The packet format differs for the Incremental and Snapshot streams. Please refer to the 'IncrementalPacket' flag (0x08) in the MsgFlags field to determine the packet type.
- New composite types have been added to the schema: 'Market Data Packet Header' and 'Incremental Packet Header'.
- The OrderLogUpdate message has been replaced with two new messages: OrderUpdate (msg id=5) and OrderExecution (msg id=6).
- Message id has been changed in the OrderBookSnapshot, SecurityDefinition, SecurityStatus, SecurityDefinitionUpdateReport, and TradingSessionStatus messages.
- The Revision field has been removed.
- The custom nullValue for the integer types has been removed, please refer to the SBE standard for the default values.
- The EmptyBook (msg id=4) message has been introduced.
- The EmptyBook (msg id=4) message is followed by the OrderBook restoration sequence of the OrderUpdate (msg id=5) messages with the PossDupFlag flag (0x10) raised.
