Payment for order flow (PFOF) is the compensation that a stockbroker receives from a market maker in exchange for the broker routing its clients' trades to that market maker. It is a controversial practice that has been called a "kickback" by its critics. Policymakers supportive of PFOF and several people in finance who have a favorable view of the practice have defended it for helping develop new investment apps, low-cost trading, and more efficient execution.
