Supplemental liquidity providers (SLPs):

Question

Quizplus · Accepted Answer

SLPs actually operate off the floor of a stock exchange and provide additional liquidity to the market by offering to buy and sell securities at specified prices. They are not floor brokers and their goal is not necessarily to seek the best price for their customers but rather to provide liquidity to the market. While they may represent stock purchasers, they also represent sellers. However, SLPs have largely been replaced by designated market makers.
