SEAQ

The Stock Exchange Automated Quotation system (or SEAQ) is a system for trading small-cap London Stock Exchange (LSE) stocks. Stocks need to have at least two market-makers to be eligible for trading via SEAQ.

In the LSE, only AIM stocks with low liquidity are traded on the SEAQ market. It is a quote-driven market made by specialized and competing dealers, also known as market-makers. The system contains no public limit order book.
