No Dealing Desk (NDD)
A No Dealing Desk (NDD) is a forex execution model in which a broker routes client orders directly to external liquidity providers—such as banks, hedge funds, or other financial institutions—without any manual intervention or internal dealing desk processing the trade.
Quick Definition Box
In a No Dealing Desk environment, your buy or sell order is sent straight to the interbank market or an aggregated pool of liquidity providers. This means the broker does not act as the counterparty to your trade, which typically results in faster execution, variable spreads, and no requotes. The broker earns revenue through a commission or a small markup on the spread, rather than by trading against you.
Detailed Explanation
To understand No Dealing Desk, it helps to contrast it with the traditional Dealing Desk (DD) model, also known as a market-maker. In a DD model, the broker takes the opposite side of your trade. If you buy EUR/USD, the broker sells it to you from its own inventory. This creates a direct conflict of interest: the broker profits when you lose money. In an NDD model, the broker has no such conflict because it does not take a position against you. Instead, it passes your order to a network of liquidity providers who compete to fill it.
There are two primary subtypes of NDD execution: STP (Straight Through Processing) and ECN (Electronic Communication Network) . In STP, the broker aggregates prices from multiple liquidity providers and sends your order to the best available one. In ECN, traders interact directly with each other and with liquidity providers on a shared platform, often seeing the full depth of the market (Level 2 data). Both are considered NDD because no human dealer or internal desk touches the order.
The key technical difference lies in how spreads and commissions are handled. In a pure NDD/ECN model, spreads are variable and can be as low as 0.0 pips during high liquidity, but the broker charges a fixed commission per lot (e.g., $7 per round turn). In an NDD/STP model, the broker may add a small markup to the raw spread (e.g., 0.2 pips) instead of charging a separate commission. In both cases, the broker's profit is transparent and does not depend on your losses.
A critical feature of NDD execution is the absence of requotes. Because the order is filled automatically by the liquidity provider at the current market price, you either get filled at the price you requested (or better, in case of positive slippage) or the order is rejected instantly if the price moves away. There is no "dealer intervention" to delay or reprice your order.
However, NDD does not eliminate slippage. During high-volatility events (e.g., non-farm payrolls), liquidity can thin out, and your order may be filled at a different price than expected. This is market slippage, not broker manipulation. In a Dealing Desk model, the broker might choose to give you a worse price to protect its own position; in NDD, slippage reflects genuine market conditions.
Real-World Example
Imagine you want to buy 1 standard lot (100,000 units) of EUR/USD. The current bid/ask is 1.1050/1.1052.
-
In a Dealing Desk (Market-Maker) model: The broker shows you a fixed spread of 1.1050/1.1052. You click "buy" at 1.1052. The broker internally records that it sold you EUR/USD at 1.1052. It may or may not hedge this position with an external provider. If the market moves against you, the broker profits. If the market moves in your favor, the broker loses. This creates a temptation for the broker to delay execution or requote you during fast markets.
-
In an NDD/STP model: The broker sends your buy order to its liquidity providers. Three banks quote: Bank A offers 1.1052, Bank B offers 1.1053, Bank C offers 1.1051. The broker's system automatically selects Bank C's quote (the best available) and fills you at 1.1051. You got a better price than the displayed spread. The broker might add a 0.2 pip markup, so your actual fill is 1.10512. You pay no separate commission.
-
In an NDD/ECN model: You see the full order book: there are offers at 1.1051 (10 lots), 1.1052 (25 lots), and 1.1053 (40 lots). You place a market order to buy 1 lot. The system matches you with the lowest offer at 1.1051. You pay a commission of $7 per round turn (opening and closing the trade). Your total cost is 1 pip of spread (1.1051 - 1.1050) plus $7 commission, which is roughly equivalent to 0.7 pips on a standard lot.
In both NDD cases, the broker had no incentive to give you a worse price. The fill was automatic and based on available liquidity.
Why It Matters for Traders
The NDD model directly affects your trading costs, execution speed, and fairness. For traders who use automated strategies, scalping, or news trading, NDD is often preferred because it eliminates the risk of dealer intervention. You can enter and exit positions at the true market price without worrying that a human dealer will reject your order or give you a requote.
For manual traders, NDD means that your stop-loss and take-profit orders are more likely to be filled at the intended level, provided market liquidity is sufficient. However, during extreme volatility, you may experience slippage—both positive and negative. This is a market reality, not a broker trick.
Another important aspect is transparency. In an NDD model, the broker's revenue comes from a clearly disclosed commission or spread markup. You can calculate your exact cost per trade. In a Dealing Desk model, the broker's profit is hidden in the spread and in the potential for adverse fills.
Common Misconceptions
Misconception 1: "NDD means no slippage."
Fact: Slippage occurs in all execution models during fast markets. NDD does not prevent slippage; it simply ensures that slippage is caused by genuine liquidity gaps, not by the broker manipulating prices.
Misconception 2: "NDD brokers never trade against clients."
Fact: While NDD brokers do not take the opposite side of your trade in the traditional sense, some NDD/STP brokers may use a "dealing desk" for certain clients or during certain hours. Always verify the broker's execution policy. Pure ECN brokers are the most transparent.
Misconception 3: "NDD always has lower spreads."
Fact: NDD spreads are variable and can be extremely low (0.0 pips) during liquid times, but they can widen significantly during news events or low liquidity. A Dealing Desk broker may offer fixed spreads that are wider on average but more predictable.

How XM Compares
XM offers both NDD (for its Zero and Ultra Low accounts) and market-maker (for its Standard account) execution models. On XM's Zero and Ultra Low accounts, trades are executed on an NDD/STP basis, meaning orders are routed directly to liquidity providers without a dealing desk. This typically results in variable spreads from 0.0 pips (Zero account) and no requotes. However, execution conditions, spreads, and commissions are subject to change based on market conditions and XM's current policies. Traders should always check the latest account specifications and terms on the official XM website before opening a position.
