Summary: Ever wondered if you can use your trading bot or mechanical strategy with the best proprietary trading firms? This article puts all the pieces together: can you code and automate your way to funded trading? I’ll share hands-on experiences, show legit examples from the world’s top prop firms, real screenshots, quote regulators and admins, and break down what actually happens when you upload your algorithm, including where people trip up and why some rules make no obvious sense. If you want to avoid getting your account flagged or banned by a prop firm for an algo, read on.
Let’s get straight to the point: can you run your EA, Python bot, or cTrader strategy at most leading prop firms? The answer is sometimes yes, with caveats—depends which firm, platform, and what “automated” means for their risk desk. Here’s the problem: rules are almost always buried in the fine print, loosely worded, or change without much warning. Google “best prop firms for algo trading”… and all you get are copy-pasted lists. But the practical workflow is so much messier.
Practically, you must start with the firm’s FAQ or Terms and Conditions. Here’s how three top prop firms treat algorithmic trading:
The setup feels simple—until you dive in. Here’s how I did it with FTMO and Topstep:
People get clever. But prop firms get even cleverer. Example—someone tried running the Waka Waka EA (well-known grid bot) overnight, thinking small lot size would pass unnoticed. FTMO caught them on overnight risk/position stacking—account suspended.
In another case, a Redditor posted about FTMO banning his “news scalper” bot after two suspicious spikes in tick volume during NFP. Data from FTMO’s dashboard explicitly listed “prohibited trading activity” for violating news constraints.
Here’s where it gets wild. Unlike stock brokers (regulated by the SEC), prop firms for forex/CFDs are mostly unregulated (see NFA for US rules, FCA for UK, but most are offshore). Each sets its own “verified” execution standards, and enforcement is murky.
Country/Firm | Standard Name | Legal Basis | Executing Authority |
---|---|---|---|
United States (Futures Firms) | NFA CFTC Reg. 1.17 | Commodity Exchange Act | CFTC, NFA |
UK (Forex) | FCA Principle 6 | Financial Services Act | FCA |
EU | MiFID II “Best Execution” | Directive 2014/65/EU | ESMA / Local Regulator |
Prop Firms (Offshore) | None (firm policy only) | Internal guidelines | Risk team |
What’s striking: In practice, unregulated/offshore prop firms are like the “wild west,” where risk managers act as judge, jury, and executioner, especially on algorithmic order flow.
Let’s say Trader A in Germany runs an EA on FTMO and passes the challenge—then FTMO finds he copy-traded B’s signals (violating their originality rule). Q: Who decides? In the UK, an FCA-licensed firm must follow strict “best execution” rules—but with FTMO (Czech entity, not FCA), the risk desk just hits “ban” based on their own logs. You appeal; they show you rule 6(b): “No unauthorized automated copying.” Finito.

I once interviewed “Vaibhav S.”, a risk officer at a leading European prop firm (anonymous by request). He said:
“The risk is not automation, but aggressive bot strategies that try to abuse latency. Our job is to filter for toxic flow, not ban every bot. But if a user uploads an off-the-shelf Martingale EA and it causes exposure we can’t cover, we shut it down—no appeal. Good coders who follow the rules and aren’t greedy? They mostly pass.”
Here’s my honest rundown: I’ve coded EAs and run signal bots at both FTMO and Topstep, and even wrote a small Python “reverse arbitrage” strategy just to see what got flagged. My own screw-up (not disabling DLL calls) cost me a real attempt, and another got pulled for stacking trades at the open (FTMO called it “toxic hedging”). But when I ran a slow, swing-style algo with clear stop loss and take-profit and no funny business—it passed.
Lesson: most firms like algo traders, as long as you aren't "gaming" the server. They want smart, transparent, risk-managed code.
Here’s the verdict. Yes, top prop firms like FTMO, Topstep, and The5ers permit algorithmic and automated trading — but only if you follow their often-byzantine rules, avoid “toxic” strategies, and don’t trip their internal risk controls. Actual enforcement is arbitrary and firm-specific (as seen in real case bans and regulatory filings).
Next steps: If you’re unsure about the rules or want to try your bot safely, sign up for a demo with a support ticket open and ask, “Is this allowed?” Or join the prop trading Discords and see what’s getting flagged in real time (screenshots don’t lie). Regulators—I’m looking at you, CFTC and FCA—still leave most prop firms under policed, so use your best judgment.
