Overview

Payment for order flow is money a trading firm pays your broker for the right to fill your trades. Click buy or sell in a trading app and your order usually does not reach an exchange. It goes to that firm instead, which takes the other side itself, out of its own inventory. For the chance to do that, the firm pays your broker a fraction of a cent per share. The firm is a market maker, and it earns the small gap between the price it buys at and the price it sells at. Your broker charges you nothing because that gap, collected across millions of orders, has already paid for your trade.

Overview

Your trading app charges you nothing, and it is not a charity. A trading firm pays it for the right to fill your orders, so your broker gets paid by the firm instead of by you. The firm buys a hair below and sells a hair above, keeps the sliver, and collects it a few million times a day. Nothing vanished when commissions went to zero. The bill moved to somebody with a reason to pick it up, and that reason is your order: it turns up, it trades, and it never knows anything the firm does not. 😎

A quick take — often all you need.

Detail

Payment for order flow is money a trading firm pays your broker for the right to fill its customers' trades. Buy or sell a hundred shares in a trading app and the order usually does not reach an exchange. A market maker takes the other side itself, and pays your broker a fraction of a cent per share for having sent it. Those fractions are what lets the app charge you no commission. The firm is not being generous. It posts two prices, a lower one at which it buys and a higher one at which it sells, and it keeps the gap between them. That gap is the bid-ask spread, and it is thin, so the firm needs orders in volume and it needs orders that will not move against it. When a fund sells four hundred thousand shares, it may have worked out something the firm has not, and the firm loses far more than the gap if the price falls right after it buys. A hundred shares sold from a phone carry no such warning, so the firm keeps its gap. That is what it is paying your broker for. Price is not left to the firm's goodwill either. It must fill you at or better than the best price publicly quoted on the exchanges, so the exchange your order skipped still sets the price you are owed, and firms usually beat it by a sliver of the spread. Regulators require these payments to be disclosed, and require brokers to seek the best execution available. The practice is permitted in the United States, banned in the United Kingdom, and being phased out in the European Union.

Detail

Payment for order flow is a trading firm paying your broker for the right to fill your trades, and it is the reason your app charges nothing. Buy or sell, and your order usually never reaches an exchange. A firm takes the other side itself and pays your broker fractions of a cent per share for having sent it. Fractions of a cent sound like nothing until you count how many orders arrive. The firm is not doing this for love. It buys a hair below and sells a hair above and keeps the difference, and that difference is thin enough that one bad trade eats a thousand good ones. Here is the part that stings the ego: you are perfect for it because you are harmless. A fund unloading four hundred thousand shares may have worked out something ugly, and whoever takes the other side finds out when the price drops. Your hundred shares carry no such warning, so the firm keeps its sliver instead of wearing a loss. Price is not where you get got, either. It has to match or beat the best public quote, and usually beats it by a fraction of a cent. What no disclosure shows you is whether that fraction was the most it could have been. The rules require the payment to be disclosed and the broker to seek the best execution available. The United States allows it, the United Kingdom banned it, and the European Union is phasing it out. 😎

Analogy

Book a hotel through a booking site and the site charges you nothing for the booking. The hotel pays it instead, a slice of the room rate, for sending that booking its way. The hotel also agrees not to quietly undercut the site, so the price you are shown is no worse than booking direct. The booking costs you nothing to make because the hotel is paying for it. Payment for order flow works the same way. Placing your order costs you nothing because a trading firm pays your broker for it, and that firm has to fill you at or better than the price quoted publicly. One thing the comparison cannot carry: a hotel is glad of any booking at all, while a trading firm wants ordinary orders specifically.

Analogy

A free newspaper costs nothing at the station, and nobody pretends the printing was free. Advertisers paid for it, and what they were buying was a reader who would sit still for twenty minutes with nothing else to look at. The paper still has to be worth reading, or you leave it in the rack. Commission-free trading runs on the same arrangement. You hand over no commission because a trading firm bought the right to fill the trade, and that firm still owes you a price at least as good as the public one, or the rules come for it. Free to place, paid for by someone who wanted your order. 😎

Formal definition — The same term, explained the usual way

Payment for order flow is compensation paid by a market maker or other executing venue to a broker-dealer in exchange for routing client orders to it for execution. It is most commonly associated with retail equity and options orders, which are internalised by wholesale market makers rather than routed to a public exchange. In the United States, the arrangement is permitted and is governed by disclosure requirements under SEC Rules 605 and 606 and by the broker-dealer's duty of best execution, which obliges execution at or better than the national best bid and offer. The United Kingdom's Financial Conduct Authority prohibits the practice, and the European Union has legislated to phase it out. Academic and regulatory analysis of its effect on execution quality is ongoing.
