RE:RE:BuyersYou usually need to have a paid data feed to get real-time quotes to those exchanges. Although the TSX is the primary exchange for most company shares, your brokerage decides where to route your order based on where they can get you the best fill. They also pay lower fees on the other exchanges and get to keep more of the comission you pay when you execute a trade. The banks helped setup the Alpha exchange to reduce the fees the TMX group charges.
