Payment for Order Flow (PFOF) is a form of compensation, usually in terms of fractions of a penny per share, that a brokerage firm receives for directing orders for trade execution to a particular market maker or exchange.
PFOF is common in options markets and is increasingly found in equity transactions. Potential advantages of PFOF may include better execution prices, greater market liquidity for our members, and helping to provide commission-free trading.
