Market Makers
Market makers are firms or desks that stand ready to buy and sell a financial instrument at publicly quoted prices, providing continuous liquidity to the market. They quote both a bid (buy) and an ask (sell) price and are prepared to trade at those prices.
Enabling Continuous Trading
By doing this, market makers help ensure that other participants can enter and exit positions quickly, even when natural buyers or sellers are not immediately available.
💡 As a trader, every time you hit buy or sell, there is often a market maker (or several) on the other side of your trade.
What Do Market Makers Actually Do?
The core job of a market maker is to provide liquidity by always being willing to trade. They:
- Continuously quote both bid and ask prices for an instrument.
- Stand ready to buy from sellers at the bid and sell to buyers at the ask.
- Adjust their quotes in response to market conditions, news and order flow.
- Hold an inventory of the instrument and manage the risk of that inventory as prices move.
🔑 Without market makers, many markets would be much less liquid, with wider spreads and slower execution.
How Do Market Makers Make Money?
Market makers typically earn money from:
💰 The Spread
They aim to buy at the bid and sell at the ask, capturing the difference (the bid-ask spread) as revenue over many transactions.
🎁 Rebates and Exchange Incentives
On some exchanges, liquidity providers receive small fees for posting limit orders.
📊 Inventory Management
Skilled market makers manage their positions to avoid large directional risk, sometimes profiting from favourable price moves while staying relatively hedged.
Key Point: Market makers are not trying to "predict" long-term direction on each trade. Their focus is on flow, spreads and risk control.
Different Types of Market Makers
Market making exists in several parts of the financial system:
Exchange-Designated
On many stock and options exchanges, specific firms or specialists are responsible for making orderly markets in particular instruments.
Bank Desks
Large banks make markets in FX, bonds, derivatives and more for institutional clients.
HFT Firms
Some high-frequency trading firms act as electronic market makers, posting and updating quotes at very high speed.
Broker-Dealer
Some retail brokers internalise order flow and effectively act as market makers to their clients.
📊 In retail trading, you may deal indirectly with several layers of market makers via your broker and its liquidity providers.
Example: Market Maker in a Stock
Suppose a market maker is quoting a stock at:
Bid
99.95
Ask
100.05
During a busy session:
- They buy shares from sellers at 99.95 and sell shares to buyers at 100.05.
- Over many trades, if they buy 10,000 shares at 99.95 and sell 10,000 at 100.05, they earn roughly 0.10 per share.
- This spread revenue helps cover their costs and the risk of holding inventory while prices move.
Result: From your perspective as a trader, you just see a tight spread and the ability to get in and out quickly. Behind that experience is the work of one or more market makers.
What Do Market Makers Mean for Retail Traders?
Market makers shape several aspects of your trading experience:
- Spreads: Tighter, more competitive market making usually means lower transaction costs for you.
- Execution quality: Good market making supports fast fills and less slippage in normal conditions.
- Behaviour in volatility: During fast markets, market makers may widen spreads or reduce quote size to manage risk, which you see as more expensive and less certain execution.
- Price continuity: Standing quotes help avoid huge gaps between trades, making charts smoother and more tradable.
🎯 Understanding this helps you see spreads and execution not as random, but as a reflection of how market makers are managing risk.
Common Misconceptions About Market Makers
"Market makers always trade against you on purpose."
Market makers take the other side of trades to provide liquidity, but they manage risk by hedging and adjusting quotes. Their goal is usually to earn the spread, not to "hunt" individual traders.
"Wider spreads always mean manipulation."
Spreads often widen in response to higher risk (news releases, low liquidity). Market makers adjust quotes to avoid being run over by sudden price moves.
"All brokers that are market makers are bad."
Some brokers use a market maker model to provide stable pricing and execution. The key issue is transparency, regulation and conflict management, not the mere existence of market making.
Quick Checkpoint: Do You Understand Market Makers?
Check if you can answer these in your own words:
- What is the main function of a market maker?
- How do market makers typically earn money?
- Why do spreads widen during volatile or illiquid periods?
- How does the presence of market makers affect your ability to enter and exit trades?
Tip: If you can explain these points clearly, you have a solid grasp of one of the most important roles in market structure.
Frequently Asked Questions: Market Makers
Are market makers always profitable?
No. While market makers have structural advantages, they also face inventory risk, competition and technology costs. Sudden market moves or errors in pricing can cause losses. Market making is a business with both risk and reward.
Do all markets have market makers?
Many liquid markets (stocks, options, FX, some crypto venues) have dedicated market makers or liquidity providers, but the structure varies. Some smaller or less liquid markets may have fewer or no formal market makers.
Is my broker a market maker?
It depends on the broker's model. Some brokers operate a dealing desk and act as market makers to clients. Others use STP/ECN models, routing orders to external liquidity providers. Some use a hybrid approach.
How can I tell if a market is well supported by market makers?
Signs of strong market making include tight, consistent spreads, good depth in the order book (on exchanges), and relatively stable pricing even during moderately busy periods. Extremely wide or inconsistent spreads can signal limited liquidity.
Summary: Why Market Makers Matter
Market makers are key liquidity providers that quote continuous bid and ask prices, helping you and other traders enter and exit positions quickly. They earn money from the spread and manage inventory risk, adjusting quotes to changing market conditions.
For retail traders, understanding market makers helps explain spreads, execution quality and how prices behave in both calm and volatile markets. Rather than seeing them only as opponents, it's more accurate to view them as part of the infrastructure that makes trading possible.
