Dark pools differ from traditional exchanges in several key ways. First, trade details such as order prices and volumes are not publicly disclosed before the trade is executed. Second, dark pools primarily support large orders, with some platforms setting minimum order sizes to filter out smaller trades. Finally, they employ unique execution methods, including centralized matching of large orders and executing trades at the midpoint of the market spread. These features allow institutional investors to execute large-scale trades at favorable prices without revealing strategic information to competitors, thereby reducing the impact on market prices.
