Is It Possible for Retail Traders to Become Market Makers?

It’s technically possible for small traders to become market makers.

Market making is not limited by the size of the entity but by its ability to comply with the rules and provide continuous liquidity to the market.

Nonetheless, there are significant challenges and it requires adherence to specific regulatory, financial, and technological requirements

Key Takeaways – Is It Possible for Retail Traders to Become Market Makers?

• Regulatory and Capital Challenges
  • Small traders trying to become market makers have to navigate strict regulatory requirements and secure substantial capital to manage securities effectively.
  • There are significant entry barriers.
• Technological Investment
  • Success in market making demands advanced technological infrastructure, including high-speed trading systems and sophisticated algorithms, which may be cost-prohibitive for small traders.
• Niche Opportunities
  • Despite the hurdles, small traders can find opportunities in less liquid markets or through quality trading strategies, where they can offer unique value and potentially thrive as market makers.

Here are several key factors small traders should consider if they aspire to become market makers:

1. Regulatory Requirements

Market makers are subject to strict regulatory requirements, including registration with the relevant financial regulatory authorities, such as the Securities and Exchange Commission (SEC) in the United States or the Financial Conduct Authority (FCA) in the United Kingdom.

They must also comply with the rules of the exchanges on which they intend to make markets.

2. Capital Requirements

To be effective, market makers must have sufficient capital to manage the inventory of securities they buy and sell.

The exact capital requirements can vary by market and jurisdiction.

But they’re typically substantial, especially in highly liquid markets.

So market makers tend to be big, institutional players.

3. Technology and Infrastructure

Market making requires sophisticated technology infrastructure, including high-speed trading platforms, advanced algorithms, and real-time data analysis tools.

Developing or acquiring such technology can be prohibitively expensive for small traders.

4. Operational Capabilities

Effective market making requires the ability to manage risk, including the use of automated systems for order execution, inventory management, and compliance monitoring.

Small traders would need to develop these operational capabilities.

5. Competitiveness

Market making is highly competitive, dominated by firms with deep pockets and cutting-edge technology.

Small traders would need to find niches where they can be competitive or offer unique value.

Strategies for Small Traders

Niche Markets

Small traders might find opportunities in less liquid or smaller markets where the large market makers are less active.

Technology and Innovation

Developing innovative trading algorithms or niche strategies can provide an edge.

Partnerships

Collaborating with technology providers or other financial institutions can help small traders overcome some barriers to entry.

Adding Liquidity

Simply adding liquidity to markets can help small traders make markets.

If no one else is willing to make a trade at a certain price, this adds value to an exchange and you can often get commission rebates.

This is what we’ll look at in the next example.

Negative Commissions

Check out this trade:

So here, the exchange paid you, and the payment was bigger than what your broker and the regulators took out.

The trade itself was selling 20 VT 6 160 calls at 0.35, routed to ISE. ISE runs maker-taker pricing.

If your order sat there as a resting offer and somebody else came along and lifted it, you were the maker.

Makers get paid a rebate. Takers pay a fee.

That’s how the exchange gets people to post quotes instead of just hitting them.

Whether that rebate actually reaches your account is a separate question, and it comes down to your commission plan.

For example, consider Interactive Brokers (the broker in this case, aka IBKR).

IBKR Tiered (cost-plus), which the account that made this trade is, every exchange fee and every exchange rebate passes straight through to you, good and bad.

On Fixed, IB absorbs the fee, keeps the rebate, and you pay the flat rate no matter what. Fixed can never print a negative number.

Rough shape of the math. Something close to:

• IB execution: 20 contracts at your tier rate, say $0.25, so about $5.00 debit
• Regulatory bits (e.g., ORF, FINRA TAF, SEC fee on the sale side, OCC clearing*): roughly $1.00 to $1.50 debit
• ISE maker rebate: 20 at maybe $0.62, so about a $12.35 credit

*Four different charges, all small.

• ORF is the exchange’s regulatory fee, a couple pennies a contract, so roughly 60 cents on the 20 contracts.
• FINRA’s TAF hits sells only and it’s under a third of a penny per contract – call it 6 cents.
• The SEC fee is also sell-side but it’s charged on dollars instead of contracts, so on $700 of premium you’re paying about 2 cents.
• OCC clearing is another 2 cents a contract, so 40 more.

Add it up, you’re around a dollar. None of it is negotiable and none of it goes to IB.

Net = about $6.25 back in your pocket.

These component numbers are illustrative. Your IB rate depends on monthly contract volume, and the ISE rebate depends on the symbol’s fee class and your customer designation. The structure we just did above is right even if the pieces aren’t exact.

Two things made this better than average:

1. VT options are thin and not penny-quoted (they go in increments of $0.05 per share, or $5 per contract with 100 shares per contract), and
2. exchanges pay up for order flow in names like that

And ISE’s best rebates go to Priority Customer orders, which basically means non-broker-dealer flow averaging under 390 orders a day. In this case, the account/client qualified.

So the gross was $700 and actually collected $706.25.

The real trade

So the most important thing. This is selling calls, in this case a covered call trade.

If VT climbs above 160 and stays there into expiration, those calls can be assigned, and you’re suddenly short 2,000 shares of VT (i.e., obligated to sell 2,000 shares of VT).

If this was naked (don’t own the underlying VT), it could be a loss that dwarfs any rebate. A $6.25 credit would be a rounding error next to that.

Never let a nice fee outcome distract you from the actual position you’re holding. The commission is a footnote to what’s a short call trade.

Can you actually build a strategy around this?

It’s not generally practical to do so.

The same order sent through SMART could land on a venue that charges you instead, and if you’d crossed the spread to hit a bid rather than resting your offer, you’d have eaten a taker fee on top of IB’s cut.

That might be 15 or 20 bucks the other direction. The credit is a byproduct of being patient and picking the venue, but it’s not an edge.

Example of Market Making Trade Execution

Here’s a step-by-step example of a simplified market-making strategy, along with how it generates profit:

Scenario

• Asset: Shares of XYZ company

• Current Best Bid: $9.99 (Someone is willing to buy at this price)

• Current Best Ask: $10.01 (Someone is willing to sell at this price)

Market Maker Strategy

• Provide Liquidity: The market maker places both a buy and a sell order:

• Buy Order: $9.98 (for 100 shares)

• Sell Order: $10.02 (for 100 shares)

• A Buyer Arrives: A buyer wants to purchase 50 shares of XYZ immediately.  They take the market maker’s sell order at $10.02

• A  Seller Arrives: Now, a seller wants to sell 75 shares of XYZ immediately. They take the market maker’s buy order at $9.98

Profit Calculation

• The Buy: The market maker bought 75 shares for $9.98 each (total cost = $748.50)

• The Sell: The market maker sold 50 shares for $10.02 each (total revenue = $501.00)

• Spread: The market maker’s profit on these trades is the difference between the buy and sell prices ($10.02 – $9.98 = $0.04 per share).

• Total Profit: Across the 50 shares they bought and sold, the total profit is $2.00 (50 shares * $0.04/share).

Key Points

• The Bid-Ask Spread: The profit for a market maker comes from the bid-ask spread. The tighter the spread, the harder it is to make a profit consistently.

• Volume: Market makers rely on high volumes of trades to generate significant profits from small spreads.

• Risk: Market makers take on risk by holding inventory. If the price of XYZ falls sharply after they bought shares, they might have to sell at a loss.

• Advanced Techniques: Real-world market making is extremely complex, involving:

• • Sophisticated algorithms for dynamic order placement

• • High-speed trading infrastructure to capitalize on tiny price discrepancies.

• • Hedging strategies to manage risk

Let’s look deeper by focusing on inventory management, risk management, and the continuous market-making process, with an emphasis on how these aspects relate to the example.

Inventory Adjustment

After executing the trades – buying 75 shares at $9.98 and selling 50 shares at $10.02 – the market maker has an additional net inventory of 25 shares of XYZ company.

The market maker must now reassess its position based on this new inventory level.

Given the market maker’s objective to facilitate trading while minimizing inventory risk, it may adjust its buy and sell orders to rebalance its inventory.

For instance, if it seeks to reduce its holding of XYZ shares to limit inventory risk, it might slightly lower its sell price to make it more attractive or increase its buy price cautiously to avoid large accumulations.

Risk Management

Holding an inventory of shares exposes the market maker to market risk – i.e., price movements against its position.

In our scenario, the market maker now holds 25 additional shares of XYZ.

If the price of XYZ falls below $9.98, the market maker faces a potential loss on those shares.

To manage this risk, the market maker might employ hedging strategies such as purchasing put options on XYZ shares, which increase in value if XYZ’s price falls, offsetting the loss on the shares.

Additionally, the market maker continuously monitors markets and adjusts its inventory levels and hedging positions dynamically to manage risk effectively.

Further Trades and Market Making

The market maker continues to provide liquidity to the market by placing new buy and sell orders around the current market price, adjusting these orders based on market conditions, inventory levels, and risk appetite.

For example, if the market maker’s analysis – e.g., via book skew and other metrics/algorithms – suggests that the price of XYZ is likely to increase, it might set its new buy order slightly higher than $9.98 to acquire more shares before the price rise.

Conversely, if expecting a price decrease, it might lower its sell order price to liquidate more of its inventory before the drop.

Through this continuous process, the market maker seeks to profit from the bid-ask spread while maintaining a manageable inventory level and mitigating risk.

Key Things to Consider in Real-world Context

• Adapting to Market Conditions – Real-world market making requires the ability to quickly adapt to changing markets, including significant news events that may impact stock/security/asset prices.
• Algorithmic Trading – Sophisticated algorithms are used for dynamically adjusting buy and sell orders, managing inventory, and implementing risk management strategies efficiently.
• Volume and Spread – While the profit per share might seem small, high trading volumes can lead to high profits. The market maker’s ability to maintain a favorable bid-ask spread under varying market conditions is key to its profitability.
• Risk Diversification – Besides hedging, market makers often diversify their risk by making markets in multiple assets, thus spreading out their exposure across different sectors or asset classes.

This example emphasizes the balance between providing liquidity, managing inventory, and lowering risk, all while striving to profit from the bid-ask spread in high-volume trading environments.

FAQs – Market Making in Retail Trading

Am I a market maker if I collected a rebate?

It just means that you provided liquidity on one fill. That’s a different animal from being a market maker.

A registered market maker signs an agreement with the exchange and takes on real obligations – post two-sided quotes nearly all day, keep the spread inside a set width, show a minimum size, stay online a required percentage of the time.

In this case, like in the real trade example we did above, it was a single limit order that was rested on the exchange and somebody filled it.

So you were the maker on that trade. But not a market maker with a quoting duty.

The rebate looks the same. But the commitment behind it is not.

Can a retail trader actually become a registered market maker?

Technically yes. Realistically, almost never worth it.

You’d register with the SEC, get approved by the exchange, and then hold up your quoting obligations every single trading day.

That means capital to carry inventory, systems fast enough to update thousands of quotes a second, and staff to handle risk and compliance.

The firms doing this (Citadel Securities, Jane Street, Susquehanna, Optiver) spend enormous sums just on infrastructure.

A solo trader competing head-on in liquid names is going to lose.

Where a small player has a shot is thin, ignored corners where the big shops don’t bother quoting.

How much money are we talking about to become an official market maker?

There’s no single number, it varies by product and exchange. But it’s steep.

Beyond regulatory net-capital minimums, you have to fund the inventory you’re constantly buying and selling, plus a buffer for when a position moves against you.

Options market makers carry thousands of open positions at once.

If even a handful gap the wrong way overnight, you need capital to absorb it and keep quoting. This is the main reason market makers are big institutions and not individuals.

If I wanted to make $10,000 a day market making, how much capital would I need?

So, how much capital to make $10,000 a day market making, and how does that compare to a normal strategy?

First things first, market making profit doesn’t scale with capital the way buy-and-hold does. It scales with volume and edge.

Capital is what lets you carry inventory and survive bad days, but it’s not the engine. So “$10,000 a day” is really a volume target, not a “how much capital do I need to have?” target.

So let’s do some math…

Say you net half a cent per share after informed traders pick you off (i.e., they trade against you right as the price moves your way). Half a cent is a decent capture in a liquid name.

To make $10,000, you’d trade about 2 million shares a day. On a $50 stock, that’s $100 million of turnover flowing through your book daily. You never hold all of it. You round-trip it fast and try to end the day flat.

But peak inventory at any instant might be 50,000 to 100,000 shares, call it $2.5M to $5M of notional sitting on your book.

Now the capital behind that. Inventory and margin on up to $5M of notional, plus a buffer for overnight gaps, ties up roughly $2M to $4M of working capital.

Regulatory net capital for a registered market-making broker-dealer climbs with how many names you quote, into seven figures for a real book, so another $1M floor.

Then technology and access: colocation, direct exchange feeds, memberships, fast execution systems. Figure $500k to a couple million a year just to keep the lights on.

All in, a serious $10k/day operation needs something like $3M to $5M of capital and $0.5M to $2M a year in fixed costs. A rough outline, not a quote.

And $10k a day across roughly 252 trading days is about $2.5M a year.

On $3M to $5M of capital, that’s a 50%-plus annual return before costs, maybe 35% to 40% after. That number looks insane next to normal investing. The S&P has returned roughly 7% to 10% a year in the long run. A genuinely good active retail trader might pull 15% to 30% in a strong stretch, but with real drawdowns along the way.

As we covered here, studies of day traders in Taiwan found only about 1% are consistently profitable net of fees, and most lose money outright.

So market making would win on paper by a mile. But that 50% is a return on speed, access, and volume, not driven by your balance sheet. You can’t buy a small slice of it.

Shrink the operation and the edge evaporates. You lose the top rebate tiers. You cross the Professional threshold we talked about and get reclassified. The informed flow outruns you and picks you off. And the fixed costs are more than a small book can cover.

Scale, unfortunately, is a big part of market making.

What is maker-taker pricing, in plain terms?

It’s how an exchange incentivizes people to post orders. When you place a resting limit order that just sits on the book, you’re “making” liquidity, and the exchange pays you a small rebate when someone trades against it.

When you cross the spread and hit an order that’s already there, you’re “taking” liquidity, and the exchange charges you a fee. The taker fees fund the maker rebates, and the exchange keeps a sliver.

It exists so the order book stays full of quotes instead of everyone just grabbing.

Why would an exchange pay me? That feels backwards.

Resting a limit order isn’t free money because it carries adverse selection risk.

When somebody fills your order, they often do it because the market is already moving against you. In the real trade example above, the resting limit was set at 0.35, and the person who bought may know the stock is about to tick up.

The rebate exists partly to pay you for taking that risk. The other reason is that retail order flow is genuinely valuable to the people on the other side, because it tends to be uninformed.

That’s the same force behind payment for order flow. Your patience gets rewarded because your patience is useful to somebody.

What’s a “Priority Customer” and why does it matter?

ISE pays its best rebates to Priority Customer orders. To qualify, you have to be a regular person (not a broker-dealer) and you can’t be flagged as a “Professional.”

The line is 390 orders a day, averaged over the month. Stay under it and you keep the top rebate.

Cross it and the exchange reclassifies you as a Professional Customer, and your rebates drop. Someone running an active automated strategy blowing past 390 orders daily would quietly lose the exact edge they were chasing.

Does my broker’s pricing plan change any of this?

Completely. On IBKR Tiered (cost-plus), fees and rebates pass through, so a negative commission is possible. On Fixed, IB pockets the rebate, eats the fee, and charges you one flat rate no matter what.

Fixed literally can’t print a negative number. So if someone using IBKR sees a negative commission, they’re on Tiered. Neither plan is “better” in the abstract.

Tiered wins when you post liquidity and collect rebates. Fixed wins when your flow mostly takes liquidity and you’d rather have one predictable cost.

Can I build a strategy around harvesting rebates?

Not really. Two things break it.

1. First, routing: send that same order through SMART and it might land on a venue that charges you instead of paying you. You don’t control where every order rests.
2. Second, if you cross the spread to hit a bid instead of waiting, you flip from maker to taker and pay a fee on top of IB’s cut.

That’s maybe $15-20 swing going the wrong way. The credit was a byproduct of being patient and picking the venue (or lucking out with the right venue), nothing more. It won’t survive being turned into a system.

Conclusion

Market making is a highly specialized and competitive area of trading.

It requires substantial investment in technology, expertise, and a deep understanding of market dynamics and regulatory requirements.

While becoming a market maker is challenging for small traders, particularly due to regulatory, capital, and technological requirements, there are pathways through niche strategies and innovative approaches.

It’s essential for small traders to conduct thorough research and possibly seek partnerships or seek niches where they can be competitive.
