The UMDF PUMA Conflated platform uses the TCP protocol, unlike UMDF which uses UDP. This platform enables Market Data distributors to use network infrastructure at lower implementation and maintenance costs. It also requires reduced bandwidth due to the subscription mechanism - through which client systems select what market data information they would like to receive - and throttling of order book updates. Trades and trade statistical data is not throttled.
UMDF PUMA Conflated is targeted at screen-based trading. It is not recommended for the usage of trading algorithms or latency-sensitive order entry systems.
How to connect?
Firms, trading customers and market data vendors may have access to the UMDF PUMA Conflated platform via the exchange co-location facilities, RCCF2 and RCB.
