Direct Market Access (DMA)
Also known as: direct market access, DMA execution, direct access trading, sponsored access
What is it?
Direct Market Access is an execution model in which your order is placed straight into the venue's order book under the broker's membership, rather than being filled by the broker acting as your counterparty. The difference shows up in three visible ways. Your order appears in the book, so you can post liquidity at your own price instead of only taking the broker's quote.
Direct market access vs a dealing-desk quote
Direct market access
- Your order enters the venue's real order book
- You can post liquidity at your own price
- Depth of market shows genuine resting size
- Paid for with a stated commission per lot
- Thin books can produce partial fills and walked levels
Transparent cost, real liquidity risk
Dealing-desk quote
- The broker fills you as your counterparty
- You take their quote, you cannot post inside it
- The spread you see is synthetic, not the book
- Paid for with a markup inside the quote
- One price for the whole order, even in thin markets
Predictable fill, cost you cannot itemise
You see real depth of market, meaning the actual resting size at each level rather than a synthetic spread. And the broker's revenue comes from a transparent commission per lot instead of a markup buried in the quote, so a DMA account typically shows a raw spread near 0.1 pips plus a stated 3.50 dollars per side rather than an all-in 1.4-pip quote. What DMA does not do is remove risk or guarantee a better fill.
You are exposed to the real book, so in thin conditions your order can walk several levels and fill worse than a market-maker's fixed quote would have. Partial fills become normal, and a large order can move the price against itself. DMA is the right model when execution transparency and posting liquidity matter to the strategy, and unnecessary overhead when they do not.
Why it matters: DMA puts your order into the real book at a stated commission instead of a marked-up quote, which makes your true cost visible and your fill dependent on genuine liquidity.
All-in DMA cost = raw spread + (round-turn commission / pip value)
Real-book exposure means fills track actual liquidity, so the same order that fills cleanly in London can walk several levels in a thin session.
Real-world example
A 5-lot EUR/USD order filled at a single price during the London session and, placed in the same size two hours after the New York close, filled across three price levels for an additional 0.6 pips of cost.
How SignalBots handles it
SignalBots connectors place orders into whatever account you have connected, so a DMA account receives the same signal with its own real-book execution and commission structure. See /risk-warning.
Pro tip
Compare a DMA account against an all-in-spread one using total cost per round turn, not the headline spread. A 0.1-pip spread with 7 dollars of commission is 0.8 pips, not 0.1.
Common pitfalls
Assuming DMA always fills better, when a thin book can produce a worse fill than a market-maker's fixed quote would have given on the same order.
Frequently asked questions
Is DMA the same as ECN or STP?
They overlap but are not identical. DMA means your order reaches the venue's book directly under the broker's membership. ECN describes a network matching participants, and STP describes passing orders to liquidity providers without a dealing desk. All three avoid the broker taking the other side.
Does DMA guarantee no conflict of interest?
It removes the main one, since the broker is not your counterparty and does not profit from your loss. It does not remove every consideration, so still check how the broker is compensated and whether any order flow is routed elsewhere.
Why do I see partial fills on a DMA account?
Because you are filling against real resting size. If only two lots are available at your price, you get two lots and the remainder works at the next level or stays in the book. A market maker would simply quote you a single price for the whole amount.
Is DMA available in retail forex?
In practice, spot forex has no central exchange, so what retail brokers label DMA is usually direct access to a pool of liquidity providers rather than to a single venue book. True exchange DMA is more common in futures, equities and some crypto venues.
Should I use DMA for an automated strategy?
It suits strategies that post limit orders, need real depth or trade size that would move a quoted market. For a bot placing small market orders a few times a day, a good all-in-spread account may cost less overall. Your capital is at risk.
