Exchange to market new data services

Investors and traders looking for more detailed share price information will soon have easier access to the London Stock Exchange’s archives, it was announced today.

The Exchange is planning to launch a Corporate Data Warehouse (CDW) to increase the range of market data it delivers to investors, data vendors and other market participants.

This will allow the Exchange to create new products by customising the real-time data it sends to customers through its London Market Information Link (LMIL), as well as providing easier access to archived trading data.

The new initiative, which will be launched in the first half of 2003, has been developed in response to strong market demand for standardised data from one central source. 

The Exchange’s market research found that centralising this data would also reduce costs for data vendors and member firms that currently have to develop the products that will be delivered through the CDW.

It will also allow the Exchange to introduce new products and services.  Initially, these will fall into three main categories:

· Real-time standardised data, including official opening prices, high and low values and an all trades Volume Weighted Average Price (VWAP) calculation;
· Real-time value-added data, such as buy and sell percentages, money flow by security and a time-weighted average spread; and
· Customised data reports and downloads covering intra-day and daily trading and order information data.

David Lester, the Exchange’s Chief Information Officer, said:

“This is an excellent business opportunity for the Exchange – our Corporate Data Warehouse will enable customers to access official standardised equity market data, both real-time and historical, from an authoritative central source. 

“The Exchange has a huge wealth of data and we are ideally placed to aggregate and process new data as it is created.”
