A No-Dealing Desk (NDD) broker is a type of forex broker that does NOT use a dealing desk to process client orders. Instead of taking the opposite side of trades (as market makers do), NDD brokers route orders directly to external liquidity providers — banks, financial institutions, and other market participants — using automated electronic systems. The two main types of NDD brokers are STP (Straight Through Processing) and ECN (Electronic Communications Network) brokers. NDD brokers earn through spread markup or commission, creating far less conflict of interest than the dealing desk m
Introduction: The Transparent Alternative to Market Making
The most important question a forex trader can ask about any broker is: does this broker profit when I lose? The answer determines everything about the quality and fairness of your trading environment.
No-Dealing Desk brokers were developed specifically to address the conflict of interest inherent in the market maker model. By removing the dealing desk from the order flow entirely — replacing it with automated electronic routing to external liquidity providers — NDD brokers create a structure where broker revenue is independent of client trading outcomes.
This guide covers everything you need to know about NDD brokers: how they work technically, the different types (STP and ECN), how they compare to dealing desk brokers, their advantages and limitations, and how to identify genuine NDD execution. Compare verified NDD brokers at CompareBroker.io.
What Does No-Dealing Desk Mean?
No-Dealing Desk (NDD) means that client orders are processed without any human dealer reviewing, approving, or intervening in the execution process. Orders pass electronically and automatically from the client’s platform to liquidity providers — with no dealing desk in between.
The absence of a dealing desk has two critical implications:
- No conflict of interest: The broker does not take the opposite side of your trade and therefore does not profit from your losses
- Real market prices: Prices shown are derived directly from external market participants rather than being constructed internally by the broker
Feature | Dealing Desk (DD) | No-Dealing Desk (NDD) |
Order processing | Dealer (human or auto) reviews orders | Fully automated electronic routing |
Counterparty | The broker itself | External LP or another market participant |
Price source | Internally constructed by broker | Real-time from multiple LPs |
Conflict of interest | High — profits from client losses | Minimal — earns from volume, not losses |
Spread type | Fixed or dealer-controlled | Variable — reflects true market conditions |
Execution type | Market maker model | STP, ECN, or hybrid |
The Two Main Types of NDD Brokers
NDD is an umbrella term that covers two distinct execution architectures: STP and ECN. Understanding the difference between them helps you choose the right type for your trading style.
Type 1: STP (Straight Through Processing) Brokers
STP brokers route client orders directly to a selected pool of liquidity providers (banks, prime brokers, institutional participants) without any dealing desk intervention. The STP system automatically selects the best available price from its LP pool and adds a small markup before presenting it to the client.
STP Feature | Detail |
Order routing | Directly to selected liquidity providers |
Price markup | Raw LP price + broker markup (0.3–1.0 pips typically) |
Commission | Often embedded in spread; some charge flat commission |
LP pool size | Typically 3–15 major banks and financial institutions |
Execution speed | Fast — typically 50–200 milliseconds |
Spread type | Variable — tracks real market conditions |
Depth of market | Not always displayed — LP prices not fully visible |
Type 2: ECN (Electronic Communications Network) Brokers
ECN brokers connect clients directly to an open electronic network where orders from multiple participants — banks, institutions, other retail traders, and the broker — interact in a live order book. ECN brokers match buy and sell orders within the network or pass them to liquidity providers, displaying full depth-of-market pricing.
ECN Feature | Detail |
Order routing | Into a live electronic network (open order book) |
Price source | Direct competition between multiple LPs — raw interbank pricing |
Commission | Flat per-lot commission ($3–$7 per standard lot round trip) |
Minimum spread | Can reach 0.0 pips on EUR/USD during liquid sessions |
Execution speed | Ultra-fast — sub-50 milliseconds on dedicated infrastructure |
Depth of market | Full Level 2 DOM visible — multiple bid/ask levels |
Order matching | Orders match within the network — true market execution |
ECN brokers represent the closest retail traders can get to interbank-quality pricing. Explore the best ECN brokers with verified spread data at CompareBroker.io.
STP vs ECN: Which NDD Type Is Right for You?
Factor | STP Broker | ECN Broker |
Typical EUR/USD spread | 0.3–1.0 pips | 0.0–0.5 pips + commission |
Commission | None (in spread) | $3–$7 per lot round trip |
Minimum deposit | Usually $0–$200 | Often $200–$500+ |
Depth of market | Not always available | Full DOM displayed |
Best for | Most retail traders | High-volume and professional traders |
Execution transparency | Good | Excellent — full order book |
Scalping friendly | Generally yes | Yes — optimal for scalpers |
Pro Tip: For most retail traders with accounts under $10,000, STP execution offers the best balance of tight spreads, accessible minimums, and genuine non-dealing-desk execution. ECN’s advantage — raw 0.0-pip spreads — is only truly cost-effective when the flat commission is small relative to your trade size, which typically requires standard lot (100,000 unit) trading.
How NDD Order Execution Works: A Technical Walkthrough
The following table traces the complete journey of a retail trader’s order through an NDD broker’s infrastructure:
Step | STP Execution | ECN Execution |
1 — Client clicks Buy | Order enters broker’s STP routing engine | Order enters ECN order book |
2 — Price selection | System queries multiple LPs for best ask | Best ask from the live order book selected |
3 — Markup applied (STP only) | Broker adds spread markup to LP price | No markup — flat commission charged separately |
4 — Order transmitted | Forwarded to selected LP automatically | Matched within ECN network or to LP |
5 — Confirmation | Trade confirmed — typically 50–200ms | Trade confirmed — typically <50ms |
6 — Risk management | LP absorbs market risk | Clearing system manages risk |
Notice that in neither model does the broker take the opposite side of your trade. The order goes directly to an external participant at every stage — this is the defining characteristic of all NDD execution.
How NDD Brokers Make Money: Revenue Without Conflict
Understanding how NDD brokers generate revenue — without profiting from client losses — explains why the model is more aligned with trader interests.
1. Spread Markup (STP)
STP brokers add a small markup (typically 0.3–1.0 pips) to the raw LP price. This markup is the broker’s revenue. It is the same amount regardless of whether the client’s trade wins or loses — making the broker’s income purely volume-dependent, not outcome-dependent.
2. Commission Per Lot (ECN / Raw Spread)
ECN brokers charge a flat fee for each lot traded — typically $3 to $7 per standard lot round trip. This commission is fixed, transparent, and completely independent of trade outcomes. Compare zero spread brokers that charge commission-based pricing for maximum transparency.
3. Rollover / Swap Revenue
NDD brokers earn a portion of the overnight financing (swap) charged to clients who hold positions past the daily rollover. This is a standard component of broker revenue that is disclosed in account specifications.
4. Volume Incentives
Because NDD broker revenue depends on trading volume — not client losses — they are structurally incentivised to help clients trade more successfully and for longer. This is the key alignment advantage of the NDD model compared to a pure B-book market maker.
Revenue Type | NDD Broker (STP/ECN) | Dealing Desk Broker |
Spread | Markup on LP price — fixed per trade | Controlled internally — wider = more profit |
Commission | Flat per lot (ECN model) | Usually none (baked into spread) |
Client losses | NOT a revenue source | Direct revenue source (B-book) |
Volume | More trading = more revenue | Client losses = revenue regardless of volume |
The Liquidity Provider Ecosystem of NDD Brokers
The quality of an NDD broker’s execution depends directly on the quality and breadth of their liquidity provider relationships. This is one of the most important — and least discussed — variables when evaluating NDD brokers.
LP Type | Description | Examples |
Tier-1 Banks | Global banks with the deepest forex liquidity | JP Morgan, Deutsche Bank, Citibank, Barclays |
Prime Brokers | Intermediaries providing credit for LP access | Major bank prime brokerage divisions |
Non-Bank Market Makers | High-frequency liquidity providers | XTX Markets, Virtu Financial, Citadel Securities |
Other Institutions | Hedge funds, sovereign funds contributing bids | Various institutional participants |
Brokers with more and higher-quality LP relationships can aggregate tighter prices, offer faster fills, and handle larger order sizes without slippage. When evaluating NDD brokers, look for those that disclose their LP relationships (even generically) in their execution quality documentation.
Regulation of NDD Brokers: What Regulators Require
Regulation is essential for NDD brokers just as it is for dealing desk brokers. Specifically, regulators require:
- Best execution obligation: FCA, ESMA, and ASIC require brokers to demonstrate they consistently achieve the best available result for clients — including price, speed, and likelihood of execution
- Execution policy disclosure: Brokers must publish their order execution policy, detailing how orders are routed, which LPs are used, and how potential conflicts of interest are managed
- Segregated client funds: Client money must be held separately from broker operating capital — protecting traders if the broker becomes insolvent
- Negative balance protection: Retail clients cannot lose more than their deposited balance (EU, UK, Australia)
- Transparent fee disclosure: All spread markups, commissions, and swap rates must be clearly disclosed
FCA-regulated NDD brokers represent the highest standard of execution quality and client protection available to retail traders. Compare FCA-regulated brokers at CompareBroker.io.

Advantages of NDD Brokers
1. Aligned Interests — No Conflict of Interest
This is the foundational advantage. NDD broker revenue is tied to your trading volume, not your trading losses. This structural alignment means NDD brokers have genuine business reasons to provide good execution, fair pricing, and tools that help you trade effectively.
2. Tighter Spreads in Liquid Markets
During the London-New York session overlap — when interbank liquidity is deepest — ECN and STP spreads can be significantly tighter than any fixed spread offered by a market maker. For active day traders, this translates directly to lower per-trade costs.
3. Real Market Pricing
Prices shown by NDD brokers reflect genuine supply and demand from the interbank market. There is no artificial spread construction — what you see is derived directly from real market participants’ quotes.
4. No Requotes (Typically)
Because NDD brokers fill orders at real-time market prices rather than dealer-approved prices, requotes are extremely rare. Orders are typically filled at the displayed price or with minimal slippage in the direction of the market.
5. Full Transparency
ECN brokers display the full depth of market — multiple price levels from different liquidity providers. This transparency is invaluable for professional traders who need to assess available liquidity before placing large orders. It is also a hallmark of the ECN broker model.
Limitations of NDD Brokers
1. Variable Spreads — Unpredictable Costs During Volatility
The flip side of real market pricing is real market volatility. During major news events, NDD spreads can widen dramatically as liquidity providers pull back. A EUR/USD spread of 0.3 pips in normal conditions can spike to 10, 20, or more pips during high-impact news. This makes cost management challenging for news traders.
2. Higher Minimum Deposits
Most NDD brokers — particularly those offering raw or zero spread ECN accounts — require higher minimum deposits than basic dealing desk accounts. Compare micro account brokers if you are starting with a smaller initial capital.
3. Commission Costs for High-Frequency Traders
While ECN commissions are transparent, they add up quickly for very high-frequency traders. At $7 per lot round trip, a scalper trading 20 lots per day pays $140 in commissions daily — regardless of profitability. Always calculate total cost (spread + commission) before comparing brokers.
4. No Guaranteed Fills
NDD brokers fill at real market prices — which means in extremely thin markets, a large order may be partially filled or slipped to the next available price. This is genuine market behaviour, not manipulation, but it can be unexpected for traders used to dealing desk guaranteed execution.
How to Verify That a Broker Is Genuinely NDD
As with STP claims, NDD is a marketing term that some brokers use loosely. Here is how to verify:
- Check the broker’s Order Execution Policy document — it must describe automated routing to external liquidity providers
- Verify that spreads are variable and reflect real market conditions (fixed spreads = market maker)
- Look for prime broker relationships disclosed in regulatory filings or their website
- Check for depth of market display — genuine ECN brokers display Level 2 DOM
- Confirm regulation by Tier-1 authority (FCA, ASIC, CySEC) — these regulators audit execution quality
- Read independent reviews with real spread measurements over time

Frequently Asked Questions: NDD Brokers
Is every STP broker also an NDD broker?
Yes — STP is a specific type of NDD execution. All STP brokers are NDD (no dealing desk intervention), but not all NDD brokers are necessarily STP — some use ECN or hybrid models. The NDD label is the umbrella category; STP and ECN are specific implementations within it.
Can NDD brokers still have a conflict of interest?
In pure A-book NDD execution, the conflict of interest is minimal. However, some brokers that market themselves as NDD still operate hybrid A/B-book models on certain client segments. The practical way to evaluate this is to assess whether the broker is regulated, whether their execution policy is transparent, and whether their spreads and execution quality hold up under real market conditions.
Are NDD brokers better for all traders?
NDD is generally better for intermediate and advanced traders who prioritise fair execution, tight spreads, and execution quality. For complete beginners, the fixed spreads and simpler platforms of regulated market makers can be more accessible. As skill and account size grow, transitioning to NDD execution typically makes sense.
What is the best NDD broker for beginners?
For beginners seeking NDD execution, STP brokers with standard accounts (built-in spread markup, no commission) are the most accessible starting point. Look for regulated brokers offering forex micro accounts and demo accounts with real NDD execution — this gives you genuine market pricing experience from day one.
Conclusion: NDD Is the Gold Standard for Execution Integrity
No-Dealing Desk execution represents the most transparent and trader-aligned model in retail forex. By routing orders directly to the market without internal counterparty risk, NDD brokers remove the fundamental conflict of interest that makes dealing desk models problematic for experienced traders.
The choice between STP and ECN within the NDD category comes down to your trading volume, preferred cost structure, and need for platform transparency. For most retail traders, STP execution with a regulated broker provides the optimal balance of tight spreads, fast execution, and genuine market pricing.
