Off-book trade reporting


TRADEcho is the suite of reporting services operated by London Stock Exchange.  As well as providing on Exchange off-book trade reporting, it is approved as an Arranged Publication Arrangement (APA) in both the UK and EU, authorised by the FCA in the UK and AFM in the Netherlands. The APA service supports over the counter (OTC) and systematic internaliser (SI) trade reporting in UK and EU MiFID II securities, regardless of the asset class.

On exchange, off book trade reporting

All securities that appear on that day’s London Stock Exchange’s market reference data file are available for on-exchange, off-book trade reporting (i.e. executions subject to the Rules of London Stock Exchange). Where a trade is executed on-exchange, the relevant market identifier code (MIC) will be published as the execution venue:

  • XLON:  Executed on London Stock Exchange UK regulated market
  • XLOM: Executed on London Stock Exchange multilateral trading facility (MTF), but not including AIM
  • AIMX: AIM security executed on London Stock Exchange MTF

The Millennium Exchange & TRADEcho Business Parameters document sets out which trading service each segment/sector combination belongs to and identifies the categorisation of individual instruments.

As well as all securities directly admitted by London Stock Exchange (Main Market, AIM, Professional Securities Market, International Securities Market and Admission to Trading only), London Stock Exchange also provides an extensive universe of equity and equity-like securities admitted by European Economic Area (EEA) regulated markets and MTFs for on-exchange trade reporting as follows:

  • Those deemed liquid by European Securities and Markets Authority (ESMA) are on the European Quoting service (EQS)
  • Those deemed not liquid by ESMA are SSX4 SXEL of SETSqx.
