SETSqx (Stock Exchange Electronic Trading Service – quotes and crosses) is a trading service for securities less liquid than those traded on SETS.

SETSqx combines a periodic electronic auction book with standalone non-electronic quote driven market making. Electronic orders can be named or anonymous and for the indicated securities order book executions will be centrally cleared.

Since 15 September 2014, the uncrossings have been re-timed to 9am, 11am, 2pm and 4:35pm.  Also a Closing Price Crossing Session has been introduced to allow a further trading opportunity at the closing auction price. Please see 'Improvements to auctions on the SETSqx trading service' in the download section for full details, including the appropriate Time in Forces that should be used. 


SEAQ is London Stock Exchange's non-electronically executable quotation service that allows market makers to quote prices in AIM securities (not traded on SETS or SETSqx) as well as a number of fixed interest securities.
