No Dealing Desk (NDD)
Market Structure & Participants
A no-dealing-desk broker passes orders directly to liquidity providers via ECN or STP routing, without taking the other side of client trades.

What is No Dealing Desk (NDD)?
No Dealing Desk (NDD) describes a broker execution model in which client orders are passed straight through to external liquidity providers — banks and other institutions streaming live prices — rather than being handled by an internal dealing desk that takes the opposite side of the trade. Under NDD, the broker acts more as an intermediary connecting traders to the wider market than as a counterparty itself.
NDD is typically implemented through one of two technologies:
- ECN (Electronic Communication Network) — orders are matched anonymously against other market participants, with pricing built from an aggregated order book and a separate commission charged per trade.
- STP (Straight-Through Processing) — orders are routed directly to liquidity providers, typically with the broker’s markup already built into the spread rather than a separate commission.
How NDD execution feels for a trader
Because NDD brokers pass orders on rather than pricing them internally, spreads are usually variable, widening or narrowing with real market liquidity and volatility rather than staying fixed. NDD accounts also generally avoid the kind of requote that can occur on dealing-desk models, since the fill reflects whatever price is genuinely available from the liquidity pool at that instant, rather than a broker deciding whether to honor a quoted price.
NDD vs. dealing desk
The key distinction from a dealing-desk / market maker model is who takes the other side of the trade. Under NDD, the broker isn’t the counterparty and its revenue comes from a transparent spread markup or commission rather than from client trading outcomes — removing a potential conflict of interest that some traders prefer to avoid. That said, being NDD doesn’t automatically make a broker cheaper or better regulated; it’s one factor among several (regulation, actual spread data, platform reliability) worth checking together.
Why it matters for traders
Traders who prioritize transparent, market-reflective pricing — particularly scalpers and algorithmic traders sensitive to execution quality — often specifically look for NDD, ECN, or STP labeling when comparing brokers. As always, verify these claims against a broker’s regulatory disclosures and independently reported spread data rather than marketing copy alone.
