Our trading services are designed to maximise liquidity in the stocks traded on them - from our premium fully electronic order-driven trading platforms for liquid UK and international securities, through to our quote driven market maker platforms for less liquid securities. Each one is designed to provide the most efficient, transparent and cost-effective way to trade the various kinds of securities on our markets.
AIM is supported by three trading platforms:
SETS
SETS is the London Stock Exchange's premier electronic trading service that combines electronic order-driven trading with integrated market maker liquidity provision, delivering guaranteed 2-way prices for the most liquid stocks. Shares in the FTSE AIM UK 50 are traded on SETS.
SETSqx
SETSqx (Stock Exchange Electronic Trading Service – quotes and crosses) supports 4 electronic auctions a day along with continuous stand alone quote driven Market Making.
SETSqx combines a periodic electronic auction book with standalone quote driven market making. Uncrossings are scheduled at 8am, 11am, 3pm and 4:35pm. Electronic orders can be named or anonymous and for the indicated securities order book executions will be centrally cleared.
SEAQ
SEAQ is the London Stock Exchange's service for AIM securities that are not traded either on SETS or SETSqx. SEAQ is a quote driven service, based on two-way quotes by participating Market Makers. There is no electronic execution in SEAQ stocks via the central market.
