Definition
The Stock Exchange Trading System (SETS) is the London Stock Exchange’s (LSE) order-driven electronic trading system, which came into operation in 1997. It has increasingly replaced the previous quote-driven system. Buyers and sellers enter their orders into the system, which matches them automatically. The price of the transaction is then recorded automatically on a trading report and passes into the settlement system. SETS covers the 250 shares of the FTSE 250 index and other blue-chip securities.
