Level 2 Enhancements

As part of a new data format by the LSE we will be including some new features
on level 2 from the 1st June, these will be found under the Research tab.

The additional features will be:

1 Market Share
This message will contain the identity of the top 5 member firms in each
security in terms of the value of business transacted on the Exchange.
The member firm's identity will be displayed using a 30 character field
but no market share percentages or associated statistics / market share
rankings will be provided. The Exchange will disseminate blank fields for
those firms that qualify for inclusion within the top 5 but have chosen
not to participate in the service. This information will be sorted in
alphabetical order and will position firms who wish to be displayed ahead
of those firms who choose to remain anonymous.

For each security we will disseminate two messages. Each message will
contain up to 5 member firm identities and 2 configurable fields as follows:
The Basis of Calculation field will be set as "T" (representing Total
Business) or "C" (representing Customer Business) to identify whether
the market share is based on the Total Value of business transacted or
just Customer business.
The Number of Days field will be set to represent the number of
business days over which the market share has been calculated.

2. Risk and Performance Measures

We will display Risk and Performance Measures via the following 4
new messages:

Price/Earnings Ratio and Market Capitalisation
Return Measures - 3 month, 6 month, 1 year, 3 years, 5 years
Alphas/Betas - 3 month,6 month, 1 year, 3 years, 5 years

Ranking field set accordingly between 1 and 5. Current percentage of
