Rules and regulations

The attractiveness of the Exchange's markets is maintained by providing an efficient and well regulated market place. As a Recognised Investment Exchange (RIE), the Exchange also has to satisfy the requirements detailed in the Financial Conduct Authority's RIE and RCH Sourcebook. Orderly markets are maintained via rules, guidance and through the monitoring of trading and market activity. Stock Exchange Notices disseminate amendments to market rules and guidance.

The Exchange's primary aim is to provide issuers, intermediaries and investors with attractive, efficient and well-regulated markets in which to raise capital and fulfil investment and trading requirements.

Rulebook
All London Stock Exchange member firms are bound by the Rules of the London Stock Exchange (“the rules”) and must ensure compliance with these rules.  The rules were fully updated in 2007 in readiness for the introduction of the Markets in Financial Instruments Directive (“MiFID”or “the Directive”).  The revised Rulebook also aligned the rules more closely with the structure of the trading system and simplified them where possible to make them more user-friendly.

The Rules are therefore closely linked to the operation of the trading system and should be read in conjunction with the Guide to the trading system and the parameters. Associated guidance and parameters are available from the downloads below.

A copy of the latest version of the Rulebook is available on the downloads below and is divided into the following sections:

Admission to trading
To be able to list on the main market, an issuer must comply with the UKLA’s requirements for granting officially listed status.  In addition an issuer must apply to the London Stock Exchange to be admitted to trading on the main market. The Exchange has a set of straight-forward admission and disclosure standards that will help you to gain admission to the main market.  For the application for admission of securities to trading Form 1 go to Regulatory Forms & Agreements. 

When issued dealing
The Exchange will permit when issued dealing in a security provided that the Exchange is satisfied that there can be a fair and orderly market for the trading of that security.

Exchange Delivery Settlement Price ("EDSP") Intraday Auction
The Exchange Delivery Settlement Price for FTSE 100 and 250 Index Futures and Options Contracts is based on the Index value created by the intra-day auction in each of the constituent securities which is run specifically for that purpose by the London Stock Exchange.
