BM&F BOVESPA Market Data is a service in real time sending news generated by the Exchange to anywhere to the world, along with news about the equity and derivatives markets.


BOVESPA Market Data Adapter works with the following market data interfaces: UMDF PUMA Conflated and UMDF. The short descriptions of these interfaces are presented below. The more detailed information is available here:


UMDF PUMA Conflated

The UMDF PUMA Conflated platform uses the TCP protocol, different to the UMDF PUMA Platform which uses a combination of the MULTICAST and UDP protocols. This platform enables Market Data distributors to use communications network infrastructures and interfaces at lower implementation and maintenance costs. It also requires reduced bandwidth as, through the signature mechanisms, it enables the recovery of BM&FBOVESPA F BOVESPA Market Data from any segment, using the same FIX session at two order book depths: Market by Price (MBP) and Market by Order (MBO).


The UMDF (Unified Market Data Feed) platform provides low latency, state of the art market data service to BM&FBOVESPA F BOVESPA customers. Client systems may access its products, encompassing the full set of Exchange-traded instruments in different asset classes: derivatives (futures, options on futures, foward, private bonds, cash equities, ETFs and options on equities) as well BM&FBOVESPAF BOVESPA's indexes: Ibovespa, IBRX-50, SMALL CAP, amongst others.


UMDF provisions for different market data channels, each one containing instrument dictionaries, order book updates, trades and statistical data that cater for different types of asset classes and products, thus allowing customers to select the market data channels of interest.


BELL Fix is a trading interface based on the FIX protocol, which the Exchange uses to publish information about the futures markets.

What are the forms of connection?

BELL Fix has been completely reformulated to permit customers with narrow bandwidth to deal with the growing volume of market data messages, without having to update their bandwidth.

Which information is available from this signal?

Consolidated BELL Fix provides top-of-book data with the five best prices for each instrument, at specified time intervals (normally 380 milliseconds). It thus avoids the need for the excessive order book updates that are relevant for high-frequency trading but which represent little value for “click and trade” customers.

Trades, statistical information and the changes to a determined instrument are published in real time. The customers’ systems can also use the BELL Fix subscription mechanism, which allows the selection of instruments, assets or products and specific market data (such as top of book, price depth book, trades, statistical data or any combination of these), thus making it possible to reduce the volume of messages even further.


The proxydiff market data feed carries BM&FBOVESPA market data for the BOVESPA segment, including the cash equities market, OTC market, BTC (Securities Lending Program) and BOVESPA FIX (private securities fixed income).

What are the forms of connection?

Firms, trading customers and market data vendors may have access to the Proxydiff platform via the Exchange co-location facilities, RCCF, RCCF2 and RCB.
