Java Market Data Handler for CME Market Data Platform (MDP 3.0) was designed to take advantage of the new low-latency data feed. It fully supports features of the CME Globex MDP3.0 market data platform(https://www.cmegroup.com/confluence/display/EPICSANDBOX/CME+MDP+3.0+Market+Data), helps feeding CME market data directly into the client application. The handler delivers market data updates from socket to your application in a few microseconds.
The Market Data Handler has two modules mbp-only and mbp-with-mbo. Mbp-only module provides high level book API for Market By Price functionality. Mbp-with-mbo module provides low level API for both Market by Order and Market By Price functionality.
With the third generation of its market data platform CME made several key improvements in the application protocol and message encoding to allow more efficient market data processing on the client side.
Matching engine event boundaries are now clearly indicated with the MatchEventIndicator (5799) tag to allow a client application apply market data updates transactionally. The client application has explicit knowledge of the moment when market data is consistent for analysis in the case of complex order book updates or multiple instruments affected by a matching event. Matching events are now independent of the UDP packet boundaries and a matching event may spread over several sequential UDP packets and a UDP packet may contain several matching events. Market data updates of a matching event are segregated by update type to allow the client application skip handling of messages not relevant to specific algorithm to reduce processing time. New trade summary messages aggregate trades by price level resulting in fewer trade updates disseminated in the case of large fill events. (http://www.cmegroup.com/confluence/display/EPICSANDBOX/MDP+3.0+Packet+Structure+Examples)
The new Simple Binary Encoding (SBE) format which replaced the FAST encoding allows more efficient and faster message decoding on the client side thanks to the fixed-length fields, native little-endian byte order and proper field alignment. The client application can efficiently access message fields directly in the buffer filled with data received from the network socket. The client application does not have to perform complex sequential state-based decoding process to access required fields. Overall the increased message encoding and decoding speed overcomes slight increase of disseminated data size and bandwidth requirements compared to the FAST compression.
With the introduction of CME MDP 3.0 platform B2BITS EPAM Systems designed new open source market data handler to take advantage of the new low-latency data feed and to provide developers with the required functionality. The new handler is optimized for both single- and multi-channel usage scenarios, the new SBE parser provides fast access to messages and message fields by tag number. With this project developers have flexibility to include this library into own applications (with/without required changes) instead of own implementation of all aspects of CME connectivity and market data handling.
- Connects and maintains connections to the CME Globex MDP 3.0 Platform;
- Provides client applications with listed Security Definitions;
- Provides client applications with all types of CME Market Data;
- Intraday Instrument subscription and synchronization;
- Packet gap detection logic based on packet sequence number to detect gaps as soon as possible;
- Per-instrument recovery logic to keep feeding Instruments not affected by a packet gap;

The interface com.epam.cme.mdp3.MarketDataListener has to be implemented and
its instance should be set in com.epam.cme.mdp3.MdpChannel.registerMarketDataListener method from mbp-only module in order to work with
high level book API for Market By Price functionality.
The project contains performance tests of incremental refresh handling. These tests are based on JMH and use test data similar to the data received on CME Certification Environment. Performance tests have the following scenario:
- MDP packet, which contains incremental refresh message (msgType = "X"), is generated;
- Real feed is emulating based on the generated MDP packet (by adjusting the sequence number on each iteration);
- MDP Handler is called to process the next MDP packet;
- Market Data entries from the MDP packet are processed in user listener (retrieving the data from entries to make it similar to regular user applications).
