SETS

What is SETS?

Stock Exchange Electronic Trading Service (SETS) is London Stock Exchange’s flagship electronic order book, trading FTSE 100, FTSE 250, FTSE Small Cap Index constituents, Exchange Traded Funds (ETFs) and Exchange Traded Products (ETPs), plus other liquid AIM, Irish and London Standard-listed securities. London Stock Exchange also operates a version of SETS on a modified trading cycle that supports securitised derivatives.

Functionally rich with multiple order types, SETS is one of the most liquid electronic order books in Europe. It is this liquidity, underpinned by a rigorous rulebook and market supervision, and a wide and diverse set of participants, that creates opportunity to do business. Market participants can choose from three fully inter-operable competing clearers, ensuring pre- and post-trade anonymity and full counterparty risk protection.
