Information Services FAQ’s


Below is a list of frequently asked questions relating to the Exchange’s information and data products for current member firms.

 

What is the quickest way to view the Exchange's data? How do I connect to the Exchange and Infolect?

There are two ways to receive real-time data from the London Stock Exchange. You can connect to the Exchange direct, receiving data via Extranex, our own fully supported network.

Alternatively you can take our data and services from a licensed distributor.


Direct Connectivity (Extranex) - Typically, market makers and traders, brokers and fund managers who rely on high performance Exchange data to inform key decisions take data directly from the Exchange.

Vendor Data – for those using our data as part of a wider investment view might prefer to connect to one of more than 100 distributors supplying around 95,000 users worldwide.


Vendor Access Network – in order to extend the geographical reach of our services, the Exchange has developed agreements with existing information vendors to allow the transmission of secured trading data across their networks.
