Drop Copy Service

Continuing the technological evolution of the negotiation's message diffusion systems, B3 has developed a new drop copy that allows processing a greater volume of messages and delivering them with lower latency. All this using a simpler operation and infrastructure model.

From an operational point of view, Drop Copy Service simplifies the configuration of rules, which brings us an increase in productivity. It changes the service distribution model by engine group and makes use of a FIX engine with greater processing capacity, which allows us to mitigate risks from a capacity point of view.

As we increase the capacity of the Drop Copy service, we eliminate delays in situations of high message throughput, and allow customers to better manage the distribution of messages in their systems.

This brings to B3 the possibility of delivering a Drop Copy service to its customers, with greater resilience and processing capacity.

Benefits of Drop Copy Service:

  • Simplification of the drop copy operation;
  • Validation of the new FIX engine;
  • Best performance;
  • Increased processing capacity in the drop copy instance;

TCP Replayer and TCP Historical Replayer

The TCP Replayer functionality allows a client to request messages that were already sent through the incremental stream during the day. These messages will be returned to the client over a TCP connection (a FIX 4.4 session). The same connection is used for both the request and the retransmission.

This method of recovery should only be used if few messages were lost. For late joiners to the market, on in case of massive loss of messages, the snapshot recovery stream should be used.

Additionally, the TCP Historical Replayer is an alternative feed with higher response time that allows querying all incremental MD messages (up to the message with sequence number 1). It is recommended only for charting purpose.

Cancel on disconnect

In the event of an involuntary disconnection of a FIX EntryPoint session for both the BOVESPA segment and for Futures, all open orders are automatically cancelled. This functionality is configurable per session, and available to all access modes. Details on how to use this functionality are available in the Order Submission Interface - Rules specification.

Flux control (Throttling)

B3 strives for the orderly execution of its markets, and for that purpose it enforces a message flow control policy. Messages that violate this policy can be queued (increasing the sense of latency) or immediately rejected. Contact the Trading Support Management (GSN) to learn more about the flow control policy and select your option.
