Are you trading on a demo account or a live account? Does your prop firm execute your trades in the real market? The execution models prop firms actually use, explained.
What actually happens to your trades
This is the question every prop firm trader eventually asks: “When I click buy on EUR/USD, does anything actually happen in the real market?”
The honest answer is: usually, no. At least not during the evaluation phase. And in many cases, not even after you’re funded. But the more important question is whether that actually matters — and the answer is more nuanced than most traders expect.
The three execution models
Simulated execution (most common)
The majority of prop firms — including most of the well-known ones — run their evaluation accounts and many of their funded accounts as simulated environments. You’re trading on a demo server. Your orders aren’t hitting any exchange or liquidity provider. The price feed is real, but the execution is synthetic.
This isn’t inherently dishonest. The firm is assessing your trading skill and paying you from its revenue — it doesn’t need to place your trades in the real market to do that. Think of it like a poker tournament: the cards and decisions are real, but the chips aren’t cash until you cash out.
Where it becomes relevant is in the quality of the simulation. A well-run simulation uses the same price feed, spread widths, and slippage models as a live account. A poorly-run simulation might show you fills that would never happen in reality — no slippage on news events, instant fills on illiquid instruments, or artificially tight spreads.
Signs you’re on a genuinely good simulation: you occasionally get slipped on entries during high-volatility events, spreads widen during rollover and news, and large position sizes show realistic market impact.
Signs you’re on a poor simulation: every fill is at your exact requested price regardless of size or timing, spreads never change, and you can trade instruments during periods when the real market is closed or illiquid.
Broker partnership execution
Some firms partner with a regulated broker who handles the actual execution infrastructure. In this model, your orders may or may not reach the live market, but the broker provides the technology layer — price feeds, order management, risk monitoring — and earns from the spread or commissions.
The prop firm pays the broker a licensing or revenue-sharing fee, and the broker provides the execution environment. From your perspective, the trading experience feels more “real” because you’re using the same platform and infrastructure that live traders use.
FTMO’s partnership with OANDA for the US market is an example of this approach. Topstep’s connection to CME for futures is another — though futures are exchange-traded, so the execution model is inherently different from OTC forex.
Live market execution (rare for funded traders)
A small number of firms do eventually route profitable traders’ orders to the live market. This typically happens only after a trader has demonstrated consistent profitability over an extended period — months or years, not weeks.
Topstep’s “Live Funded” tier is the most transparent example. Their own published data shows 0.71% of Express Funded traders reach this stage. That means for every 1,000 traders who pass the Trading Combine and receive a funded account, roughly 7 will ever trade with real capital deployed in the CME.
For firms that do route to live markets, the decision to do so is driven by economics: if a trader is consistently profitable, it’s cheaper for the firm to earn a profit split from real market gains than to pay from its own cash reserves.
Does it matter whether your trades are “real”?
This is where traders often get caught up in a philosophical debate that misses the practical point.
What matters:
- Can you withdraw real money? If the firm consistently pays out real USD/EUR/GBP to your bank account, the execution model is secondary.
- Is the price feed accurate? If you’re trading on the same prices as the live market, your skill development is genuine.
- Are the fills realistic? If the simulation gives you unrealistic fills, your trading results won’t translate to a live account — which matters if you ever trade your own capital.
What doesn’t matter as much as traders think:
- Whether a market maker “saw” your 0.5 lot EUR/USD order. Your position size at a prop firm is a rounding error in the forex market’s $7.5 trillion daily volume.
- Whether the firm is “making money from your losses.” If you lose, you lose access to the funded account and need to buy another challenge. The firm doesn’t need to B-book your trades to profit from your failure — the challenge fee model already handles that.
The risk management angle
What does matter — significantly — is how the execution model affects the firm’s stability.
A firm running pure simulation has very low operational risk. It collects challenge fees, runs a software platform, and pays out a percentage of revenue to successful traders. The only risk is the payout ratio exceeding the fee income.
A firm running live execution has market risk. If funded traders are profitable and the firm is passing those trades to the market, the firm earns its share of real profits. But if the firm is taking the opposite side of trades (acting as a counterparty), it carries the risk that traders are collectively right about market direction.
This is why firms that offer very high leverage, very wide instrument coverage, and very loose trading rules on funded accounts should give you pause. They’re either running pure simulation (in which case the “leverage” is meaningless), or they’re taking on significant market risk (in which case the firm’s stability depends on its risk management, not just its cash reserves).
What to look for
When evaluating a prop firm’s execution model, ask yourself:
Does the firm disclose its model? Firms like Topstep are transparent about the journey from simulated to live accounts. Firms that claim “you’re trading real money from day one” on a $200K account you accessed with a $300 challenge fee are almost certainly not telling the full story.
Is the firm backed by a regulated broker? A broker partnership adds a layer of infrastructure and credibility. The broker has its own regulatory obligations and reputation to protect, which provides an indirect check on the prop firm’s operations.
Are the trading conditions realistic? Test for spread widening during news events, slippage on limit orders, and rollover behaviour. If the simulation is unrealistically smooth, your edge might not survive the transition to live markets.
Does the firm have a clear path to live trading? If a firm claims all funded traders trade live capital, ask for documentation. If it’s genuinely live execution, there should be evidence: regulatory disclosures, broker partnerships, or at minimum, a clear explanation of the execution flow.
The execution model isn’t the most important factor in choosing a prop firm — payout history and firm stability matter more. But understanding what happens when you click “buy” helps you evaluate the firm’s claims, assess its risk profile, and set realistic expectations about what your funded account actually represents.
