Larger Size Market Maker

The London Stock Exchange Larger Size Market Maker initiative is part of the Exchange’s continuing efforts to improve our markets’ depth and liquidity. 
The voluntary scheme means participating Market Makers are obliged to make prices in larger sizes with tighter spreads in non FTSE 350 equity securities, increasing flow liquidity and flow for Market Makers and reducing the cost of trading for brokers.

A Larger Size Market Maker may also opt to be bound off book in all its Non-midcap SETSmm registered securities up to the displayed price and size to all enquiring member firms.
