Which prop firms allow Expert Advisors? A rule-by-rule comparison (2026)

The question that matters most: your own EA or a purchased one

Most prop firm EA policies were written with two cases in mind: traders who build their own robot, and traders who copy a signal or run the same commercial robot as hundreds of others. Firms are generally comfortable with the first and cautious about the second, because many identical accounts placing identical trades looks like copy trading and can overload the firm's risk systems.

That means a general statement that a firm allows EAs does not tell you whether a commercial, purchased EA is acceptable. Some firms require you to own or be able to show the source code. Some allow purchased EAs only as trade or risk managers. Some require pre-approval. Always ask the firm directly, in writing, whether the specific EA you intend to use is acceptable, and keep the answer.

FTMO

FTMO is widely reported to permit Expert Advisors on MT4 and MT5, including third-party ones, provided they do not engage in forbidden practices. The practices most often cited are latency or arbitrage exploitation, high-frequency trading that exploits infrastructure, copying signals from external sources, and activity that overloads the server. One frequently quoted figure is a limit of about 2,000 server requests per day, which is an indicator that an extremely busy EA can be flagged as hyperactive.

FTMO also assesses trading behaviour, such as how consistent your position sizes and trade frequency are. Secondary sources disagree on some points, so read FTMO's current trading objectives and ask support about your specific strategy.

FundedNext

FundedNext's help centre states that EAs and bots are allowed on MT4 and MT5 for accounts below a certain size, with an additional EA usage fee, and that larger accounts must be traded manually. EAs are not allowed on the cTrader and Match-Trader platforms. The restriction on larger accounts is described as covering even tools that only adjust stop loss, take profit or lot size.

Latency abuse, arbitrage and order flooding are consistently described as prohibited. Third-party blogs disagree on whether martingale and grid EAs are allowed, so confirm that in the current help centre before relying on it.

The5ers

The5ers' FAQ allows EAs in general, with several conditions. It states that the trader must own the source code of the EA, that copying other people's signals is not allowed, and that tick scalping, latency or reverse arbitrage, hedge arbitrage, high-frequency trading and emulators are banned. It also requires that the stop loss is visible on the trading platform, so hidden or stealth stops are not accepted. Accounts that break these rules can be cancelled without refund.

Because of the source-code ownership rule, a commercial EA delivered only as a compiled .ex5 file is unlikely to satisfy this policy. Ask The5ers before you rely on one.

FundingPips

FundingPips is reported to allow your own EA, fully automated, if you can prove ownership, for example with source code and development history. Third-party EAs are described as permitted only as trade or risk managers, with off-the-shelf bots not permitted. Banned practices reported include high-frequency trading, tick scalping, server spamming, latency arbitrage, hedging and long-short arbitrage. Martingale and grid strategies are commonly listed as restricted or banned.

There are also profit-counting rules, for example trades closed within one minute of opening and profits made around high-impact news may not count towards a payout. Check the current figures on the firm's rules page, since sources quote different time windows.

E8 Markets, FXIFY, Alpha Capital and others

Several other firms publish EA-friendly policies, but the detail varies. Some listings describe E8 Markets as allowing EAs, bots and algorithms including martingale and grid, but its per-strategy rules should be verified because older rule pages were archived. FXIFY is reported to allow EAs with pre-approval. Alpha Capital Group is reported inconsistently, with some sources describing trade-assistance EAs only and pre-approval required.

The pattern is that firms increasingly distinguish between a fully automated strategy you own, a purchased strategy, and a trade-management tool. Expect the rules to continue shifting.

Prohibited practices almost every firm shares

Regardless of firm, a few practices appear on nearly every banned list.

• Latency arbitrage and any exploitation of price-feed delays.
• High-frequency trading and excessive order or modification requests (server spamming).
• Tick scalping and ultra-short holding times.
• Copy trading from external signals or the same strategy on many accounts.
• Hedging across accounts, reverse trading and any coordinated account abuse.
• Using platform bugs, price glitches or off-market quotes.

How to check a firm's current rules before you pay

Read the firm's official rules or help centre page, not a review site, since review sites are often affiliate-driven and out of date. Ask support in writing three questions: is this specific EA acceptable, does it need to be pre-approved, and what are the restrictions on trade duration, news and holding over weekends. Keep the reply.

Run the EA on a demo account with the firm's drawdown and trading conditions first. No EA can guarantee a pass, and challenge fees are at risk.
