Good financial markets require fairness and a good gauge of fairness is transparency, thus for the direct trading platform cats, the pre-and post-trade transparency is important. In 2017 the change in market regulation with MiFID II will formalize the transparency that we see as a necessary tool of operation today. Anywhere, anytime, in real-time, data on more than one million instruments is available on cats. On busy trading days, the 24 market makers from 5 European centers create more than 4 billion instrument updates.

Together with Boerse Stuttgart cats, we explored the possibilities and a new way of disclosing this information. In just a matter of weeks, we created the cats Market Data Platform, capable of displaying market maker quotes, client requests for quotes, and trade information. The tool provides end-users first with live quotes and with a comprehensive picture of their trade in an enormity of market data.

Likewise, market makers and retail brokers use this platform to explain and evidence pricing and transactions. A secure part of the site provides the counterparties, or market regulators, with a view of in-depth transaction data and an online visual display of the actual characteristics of the instrument quotes received in the market.
