Market Maker
A market maker is a financial intermediary that continuously quotes both a buy (bid) and a sell (ask) price for a financial instrument, committing to execute trades at those prices to provide liquidity to the market.
Quick Definition Box
A market maker ensures that traders can always buy or sell an asset by posting two-sided quotes. They profit from the spread (the difference between bid and ask) and manage inventory risk. In forex and CFD trading, market makers often act as the counterparty to retail trades, which can lead to conflicts of interest like requotes or slippage during volatile periods.
Detailed Explanation
A market maker’s core function is to create a liquid market where buyers and sellers can transact instantly, even when no natural counterparty exists. Without market makers, a trader wanting to sell 100,000 units of EUR/USD might wait hours for a buyer. The market maker fills that gap by always being ready to take the other side of the trade.
The mechanics are straightforward: a market maker posts a bid price (the highest price they will pay to buy) and an ask price (the lowest price they will sell at). The difference between these two prices is the spread, which represents the market maker’s gross profit per round-turn trade. For example, if a market maker quotes EUR/USD at 1.1050/1.1052, the spread is 2 pips. If a trader buys at 1.1052 and immediately sells at 1.1050, the market maker earns 2 pips (minus any costs).
Market makers manage significant inventory risk. If they accumulate a large long position in USD/JPY and the dollar weakens, they face losses. To hedge, they may offset positions in the interbank market or adjust their quotes to attract opposite flow. During news events, they widen spreads to compensate for increased volatility risk.
In retail forex and CFD trading, there are two main execution models involving market makers:
- Dealing Desk (DD): The broker acts as the market maker, taking the opposite side of client trades. This is also called a "market maker model."
- No-Dealing Desk (NDD): The broker passes client orders directly to external liquidity providers (often large bank market makers) without taking the opposite side. This includes STP (Straight Through Processing) and ECN (Electronic Communication Network) models.
The key distinction: in a dealing desk model, the broker’s profit can come from client losses (since they are the counterparty), creating a potential conflict of interest. In NDD models, the broker earns only commission or a markup on the spread.
Real-World Example
Imagine a retail trader, Sarah, wants to buy 1 standard lot (100,000 units) of GBP/USD. The current market price is 1.3000.
Scenario A: Market Maker (Dealing Desk) Broker
- The broker’s market maker desk quotes: Bid 1.2998, Ask 1.3002 (4-pip spread).
- Sarah buys at 1.3002. The broker is now short 100,000 GBP.
- If GBP/USD falls to 1.2990, Sarah’s position is losing. The broker profits from her loss (since they are short).
- If GBP/USD rises to 1.3010, Sarah profits, and the broker loses. The broker may hedge by buying GBP/USD in the interbank market to limit risk.
Scenario B: ECN/STP Broker (No Market Maker)
- The broker aggregates quotes from multiple bank market makers: Best bid 1.2999, Best ask 1.3001 (2-pip spread).
- Sarah buys at 1.3001. The broker passes the order to a bank market maker, earning a small commission (e.g., $7 per lot).
- The broker has no directional exposure; they profit regardless of whether Sarah wins or loses.
In Scenario A, the market maker broker may also use "requotes" during fast markets — rejecting Sarah’s price and offering a new, less favorable one. In Scenario B, Sarah may experience "slippage" (execution at a worse price) but rarely requotes.
Why It Matters for Traders
Understanding whether your broker operates as a market maker or uses an NDD model directly affects your trading experience:
- Execution Speed: Market maker brokers often execute instantly in normal conditions but may requote during news. NDD brokers may have variable execution speeds depending on liquidity.
- Spread Costs: Market makers typically offer fixed spreads (e.g., 2 pips on EUR/USD) regardless of market conditions. NDD brokers offer variable spreads that can be as low as 0.1 pips during liquid times but widen significantly during volatility.
- Conflict of Interest: With a market maker broker, your loss can be their gain. This doesn’t mean they manipulate prices (regulated brokers cannot), but it creates an incentive structure that favors the broker when you lose.
- Slippage vs. Requotes: Market maker brokers tend to use requotes (you must accept a new price), while NDD brokers use slippage (your order fills at the next available price). Neither is inherently better — requotes give you control but can cause missed opportunities; slippage executes automatically but may be at a worse price.
Traders using scalping or high-frequency strategies often prefer NDD/ECN brokers because requotes destroy their edge. Long-term position traders may find market maker brokers acceptable due to fixed spreads and simpler pricing.
Common Misconceptions
Misconception 1: "All market makers are dishonest and manipulate prices." Fact: Regulated market makers (e.g., those under FCA, CySEC, ASIC) must follow strict rules. They cannot arbitrarily move prices against clients. However, they may widen spreads or use requotes during volatile periods as a risk management tool. The conflict of interest is structural, not necessarily malicious.
Misconception 2: "Market makers always lose when clients win." Fact: Market makers hedge their risk. If a client has a large winning position, the market maker may offset that risk in the interbank market, limiting their loss. Their primary profit comes from the spread, not from client losses.
Misconception 3: "ECN/STP brokers are always better than market maker brokers." Fact: ECN/STP brokers offer tighter spreads but may have variable spreads that widen dramatically during news. Market maker brokers offer predictability (fixed spreads) but may have requotes. The "better" choice depends on your trading style.

How XM Compares
XM operates as a No-Dealing Desk (NDD) broker for most account types, meaning they do not act as a market maker taking the opposite side of client trades. Instead, XM aggregates liquidity from multiple tier-1 banks and passes client orders directly to these providers. This structure aims to reduce conflicts of interest and provide transparent execution. XM also offers fixed spread accounts (Micro and Standard accounts) where spreads are set by the broker, but these are still executed on an NDD basis — the broker does not trade against clients. For the most current information on execution models, spreads, and account types, traders should verify details on XM’s official website.
