How Payment for Order Flow Works and Why Your Broker Receives It
What payment for order flow actually is
Payment for order flow is money a market maker or trading firm pays your brokerage for the right to execute your stock or options trades. When you place an order to buy or sell, your broker doesn't always send it directly to an exchange. Instead, they can route it to a firm that will fill it—and that firm pays your broker for the opportunity. You don't pay this fee directly; it happens behind the scenes.
The payment exists because market makers profit from the difference between the bid price (what buyers offer) and the ask price (what sellers want). If your broker sends them consistent order flow, they can predict patterns and manage their risk better. That predictability has value, so they pay for it. Your broker keeps that money as revenue.
This practice is legal and disclosed, but it creates a conflict of interest: your broker has a financial incentive to route your order to whoever pays the most, not necessarily to whoever gives you the best price. Understanding how this works helps you see where your actual costs hide.
Key Takeaways
- Payment for order flow is money a market maker pays your broker to execute your trades, not a fee you see on your statement.
- Your broker profits from this arrangement, which can create pressure to route orders to the highest payer rather than the best price for you.
- The SEC requires brokers to disclose payment for order flow, but the disclosure is often buried in account documents or online.
- Brokers that do not accept payment for order flow typically charge commissions or higher spreads instead.
- The difference in execution price between routing options can add up over many trades, especially for options orders.
How the money flows from market maker to your broker
When you submit a buy or sell order, your broker's system routes it somewhere. That somewhere is usually not the New York Stock Exchange or NASDAQ directly. Instead, it goes to a wholesaler or market maker—a firm like Citadel Securities, Virtu Financial, or Jane Street that specializes in filling retail orders.
These firms make money by buying at the bid price and selling at the ask price. If they receive thousands of orders from your broker every day, they can predict flows and manage inventory efficiently. That consistency is worth paying for. The payment ranges from a fraction of a cent per share for stocks to several cents per contract for options, depending on the order size and type.
Your broker receives this payment and records it as revenue. Some brokers pass a portion to you in the form of rebates or better pricing; most keep it. The SEC requires brokers to disclose the total amount they receive, but that disclosure usually appears in quarterly reports or fine-print account documents, not in your monthly statement.
Where to find what your broker receives
The SEC requires brokers to publish a payment for order flow disclosure that shows how much they received per share or per contract, broken down by asset type (stocks, options, bonds). This document is usually on your broker's website under "Disclosures," "Regulatory Information," or "Order Routing."
You can also request this information directly from your broker's customer service. Ask for the "PFOF disclosure" or "order routing disclosure." They are required to provide it. Some brokers, like Fidelity and Charles Schwab, publish detailed quarterly reports showing the exact firms they route to and how much they received from each.
If your broker does not publish this information online, that is a red flag. Transparency about order routing is a basic regulatory requirement, and a broker that makes it hard to find may be less concerned about your execution quality.
The trade-off: payment for order flow versus commissions and spreads
Brokers choose between two business models. Some accept payment for order flow and charge you zero commissions. Others refuse PFOF and charge you a commission per trade or widen their spreads to cover costs. Neither model is inherently better; the question is which one costs you less in practice.
A broker that accepts PFOF might execute your stock order at a slightly worse price than a broker that routes to the exchange directly, but you pay no commission. A broker that refuses PFOF might execute at a better price but charge you $5 or $10 per trade. Over a year of frequent trading, the math can favor either side.
For options, the difference is usually larger. Market makers can afford to pay more for options order flow because the spread is wider. If you trade options frequently, comparing PFOF disclosures between brokers can reveal real cost differences. A broker receiving 5 cents per contract versus 2 cents per contract will cost you noticeably more over time.
Why execution quality matters more than the payment itself
The real issue is not that payment for order flow exists—it is that it can incentivize poor execution. If Firm A pays your broker 2 cents per share and Firm B pays 3 cents per share, your broker has a financial reason to route to Firm B. But if Firm B's bid-ask spread is wider, you might get a worse price even though your broker earned more.
The SEC requires brokers to route orders to achieve "best execution," which means the most favorable terms considering price, speed, and likelihood of execution. But "best execution" is measured over time and in aggregate, not on every single trade. A broker can route some orders to the highest payer and still claim compliance if the overall results are reasonable.
This is why checking your actual fill prices matters. If you place a limit order to buy at $50 and it fills at $50.05, you are paying the difference. If that happens repeatedly, your broker's routing choices are costing you money. Comparing your fills to the market price at the time of execution is the only way to know if you are getting a fair deal.
Brokers that do not accept payment for order flow
Some brokers have built their reputation on refusing PFOF. Interactive Brokers and Lightspeed are examples; they charge commissions instead. For very active traders, especially those trading options or penny stocks, this model can be cheaper because execution quality is the only competitive advantage.
These brokers typically route orders directly to exchanges or to market makers that do not pay for flow. The trade-off is that you pay per trade, so if you make many small trades, costs add up. But if you make fewer, larger trades, the commission model can be cheaper than PFOF.
If you are a casual investor making a few trades per month, the difference between PFOF and commission brokers is usually small. If you trade daily or trade options regularly, it is worth comparing the actual costs. Pull your last three months of statements and calculate total commissions or PFOF-related slippage at each broker.
What changed after the SEC's 2020 order routing rules
In 2020, the SEC updated order routing rules to require brokers to disclose more detail about where orders go and how much they receive. Brokers must now publish quarterly reports showing the percentage of orders routed to each venue and the payment received from each. This transparency made it easier to compare brokers, but it did not eliminate PFOF.
The rules also tightened the definition of "best execution," requiring brokers to consider not just price but also the likelihood that an order will be filled and the speed of execution. In practice, this has pushed some brokers to route more orders to exchanges and fewer to wholesalers, but PFOF remains the dominant model for retail stock and options trading.
The SEC continues to review PFOF and has proposed additional restrictions, but as of now, it remains legal and widespread. Staying informed about your broker's routing practices is your best defense against hidden costs.
Frequently Asked Questions
Does payment for order flow mean I am getting a worse price?
Not necessarily. A market maker that pays for order flow can still offer competitive prices because they profit from volume and bid-ask spreads. The risk is that your broker routes to the highest payer rather than the best price. Checking your actual fills against the market price at execution time is the only way to know.
Can I opt out of payment for order flow?
Most brokers do not offer an opt-out for individual trades. Your choice is to switch to a broker that does not accept PFOF, which usually means paying commissions instead. Some brokers let you choose between commission and PFOF models for different account types.
Is payment for order flow the same as a kickback?
Legally, no. A kickback implies a hidden payment that benefits the broker at your expense. PFOF is disclosed and regulated. However, the effect can be similar if your broker prioritizes payment over execution quality. That is why disclosure and monitoring your fills matter.
Why do brokers offer free trading if they accept payment for order flow?
Because PFOF revenue replaces commission revenue. A broker that receives 1 to 2 cents per share from market makers can afford to charge you zero commissions and still be profitable. The payment for order flow is their business model, not a hidden subsidy.
Should I switch brokers based on their PFOF disclosure?
Only if you trade frequently or in large size. For casual investors, the difference between brokers is usually small. For active traders, comparing PFOF amounts and actual execution prices across brokers can reveal real savings. Calculate your total trading costs over three months at each broker before deciding.
