Market Maker (Dealing Desk) Broker
Also known as: dealing desk broker, DD broker, market maker, B-book broker
What is it?
A market maker broker, also called a dealing desk broker, takes the other side of your trade from its own book instead of passing your order out to the wider market. When you click buy, the broker sells to you; when you sell, it buys from you. It quotes you a price and becomes your direct counterparty.

This is the opposite of an ECN broker, which routes your order to external liquidity providers and matches you against real market participants. Because the dealing desk sets its own quotes, you usually get fixed spreads and instant fills, but the broker profits partly when you lose. Say you go long 1 lot of EUR/USD at 1.1000.
The market maker does not find a seller in the market; it simply books the opposite position internally. If price drops to 1.0980, your 20-pip loss is largely the broker's gain unless it has hedged that exposure elsewhere.
Why it matters: It shapes your spreads, fill speed, and whether your broker profits when you lose, so it directly affects every execution.
The execution model decides your fill quality and cost structure, which compounds across every trade you place.
Real-world example
If you buy 0.5 lots of GBP/USD at 1.2700 through a dealing desk, the broker books the short side itself rather than routing to an ECN, and may requote you 1.2702 in fast markets instead of filling at your clicked price.
How SignalBots handles it
SignalBots Signals quote a precise entry, but a dealing desk broker may fill you a pip or two away, so match each signal to a broker whose execution holds up. See /risk-warning.
Pro tip
Check whether your broker runs a dealing desk or no-dealing-desk model before scalping news, since requotes and rejected fills are far more common on a market maker.
Common pitfalls
Assuming a tight fixed spread means cheaper trading, when a dealing desk can offset it with requotes, slippage on your fills, and slower execution.
Frequently asked questions
Is a market maker broker bad for traders?
Not inherently. Dealing desks offer fixed spreads and instant fills that suit many traders, but the broker profits when you lose, so execution quality varies and your capital is at risk. Choose a regulated one.
How do I know if my broker is a market maker?
Check the account or execution type in the broker's terms. Fixed spreads, instant execution, and frequent requotes usually signal a dealing desk, while raw spreads plus commission point to an ECN model.
Market maker vs ECN broker — which is better?
Neither wins outright. ECN suits high-volume scalpers and news traders wanting raw market pricing; a market maker can suit beginners and small accounts. Your trading style and capital at risk decide the fit.
Do market makers trade against you?
Yes, by design they take the opposite side of your order on their book. A reputable dealing desk often hedges that net exposure externally rather than betting against each individual client.
Can a dealing desk broker manipulate prices?
A regulated broker quotes off real interbank rates and is audited, limiting abuse. Unregulated dealing desks carry more risk of widened spreads or stop hunting, so regulation matters and your capital is at risk.
