Payment for Order Flow (PFOF)
The Formal Definition
The compensation a brokerage firm receives from market-making wholesalers in exchange for directing retail client orders to them for trade execution rather than public exchanges.
PFOF Revenue = (Cents per Share) × Total Order Volume
Cole Barrett's Reality Check
The Unvarnished Bottom Line"When a broker gives you something for 'free', you are the product. Under PFOF, your retail order is packaged as 'uninformed flow' and sold to high-frequency market makers who profit by stepping in front of public market pricing."

How Brokers Weaponize This Term
Brokers hide PFOF behind $0 commission marketing while collecting hundreds of millions annually from market makers. Regulators like the UK FCA have banned PFOF entirely due to structural conflicts of interest.
