Prop Firms That Allow EAs
Almost every prop firm comparison table puts a tick beside "EAs allowed". We read the published rules of six firms and not one of them cleanly permits a commercially-bought Expert Advisor. Three ban third-party EAs outright, two allow them only if no other trader is running the same one, and only two offer MetaTrader 4 at all.
Every rule on this page was read from the firm's own website, help centre or terms, and is quoted rather than paraphrased wherever the wording matters. Each firm's section carries a link to the page we read it on.
The Six Firms, Side By Side
| Firm | Commercially-bought EA | Drawdown type | Max overall loss | Verified |
|---|---|---|---|---|
| FTMO | Permitted, with a capital-allocation warning | Static (2-Step) / end-of-day trailing (1-Step) | 10% | 17 Sep 2026 |
| FundedNext | Paid add-on, distinct strategy required, some EAs banned by name | Static or trailing by model | 6–10% | 17 Sep 2026 |
| The5ers | No — trader must own the source code | Equity-based | 5–10% by product | 16 Sep 2026 |
| Alpha Capital | No — independent execution prohibited | Static or trailing high-water mark | 4–10% by product | 16 Sep 2026 |
| E8 Markets | Permitted until two users run the same one | Closed-balance trailing, or static | 4–8% by product | 16 Sep 2026 |
| Instant Funding | No — publicly available EAs not permitted | Smart, static or end-of-day trailing | 4–10% by product | 16 Sep 2026 |
MetaTrader 4 is offered by FTMO and FundedNext only. The other four are MT5 and newer platforms. Much of the commercial EA market is still MT4-only, so for many readers four of these six are unusable before any rule is reached.
Ranges are shown where a firm sells several products at different limits. Naming one headline figure for a firm whose drawdown is chosen at checkout would be wrong, so we don't. How each drawdown type works covers what these differences mean in practice.
What Each Firm Actually Says
FTMO
Founded 2015 · MT4, MT5, cTrader, TradingView
EAs are permitted. FTMO accepts "whether it's discretionary trading, algorithmic trading, EAs, etc." provided trading is "legitimate (in line with proper risk management)" and "conforms to the real market conditions."
Read that carefully. It does not say you cannot pass. It says you can pass and still be denied the funded account.
The capital allocation rule has a number on it. FTMO states there is "no limit to the number of accounts you may have", but that "at any given time, the total capital allocation across all accounts is limited to $400,000 per trader or strategy (prior to any scaling)." It adds that "if identically traded strategies are detected across multiple FTMO accounts and the total fictitious capital exceeds the maximum capital allocation limit, FTMO reserves the right to suspend the affected accounts."
Per trader or strategy. A widely-sold Expert Advisor is one strategy running in many accounts, which is precisely why the warning above exists. Copy trading and prop firms covers how this works and how firms identify it.
Forbidden practices include EAs "which cause the trading account to become hyperactive", and "trading strategies that artificially distribute profit across multiple days without proportionally distributing market risk, such as hedging or holding opposing positions on the same or highly correlated instruments." FTMO does not name grid or martingale anywhere — but that clause describes what a basket EA on correlated pairs does.
Maximum Loss is 10% of initial capital in all phases, measured on equity. The 2-Step limit is static. The 1-Step limit trails: the "boundary is derived from the highest balance you reach at the end of the trading day, rather than from intraday fluctuations (equity)", the amount is "10% of the initial simulated balance", and "if the balance at the end of the next day is lower, the limit remains unchanged." It rises with new end-of-day highs and never falls.
Maximum Daily Loss is 5% on the 2-Step and 3% on the 1-Step, and it counts open positions. FTMO's wording: "the rule is based on equity, not only on closed results… the calculation includes both the results of closed positions and the floating P/L of open positions, as well as commissions and swaps." The baseline is the "account balance at midnight CE(S)T of the previous day."
That last point decides more challenges than any other rule on this page. A grid EA sitting on unrealised losses is already spending its daily limit.
Server caps: 200 open orders, 2,000 positions per day.

FundedNext
Brand founded 2022 · MT4 and MT5 for EAs; not cTrader or Match-Trader
EAs are a paid add-on, not a standard feature: "EA and bot trading are not allowed on cTrader and Match-Trader, regardless of account size."
The conditions are strict. "Traders are required to customize their EA or bot settings to align with their unique trading styles." "Each EA or bot is required to employ a distinct strategy, avoiding identical trades across any accounts within FundedNext." There is "a maximum allocation limit of $300,000 for each EA or trading bot's strategy."
FundedNext names specific commercial EAs and bans them: The Prop Pilot EA, PropEA (Fxblood Capital), Gold OneShot EA MT5, Forex Flex EA, and X Pass Bot. At least one of those is marketed by its vendor as a prop firm product.
The grid and martingale split is unusual and matters. "Grid trading is prohibited because it can lead to market manipulation and create artificial activity." But "FundedNext does not impose any limitations or restrictions on trader's strategy, whether it involves discretionary trading or EAs that employ martingale strategies." Many commercial EAs are both at once, and FundedNext publishes no guidance on how it classifies them.
Daily loss "includes realized and unrealized P&L, swap, and commission." US traders are offered Match-Trader only, so US traders cannot run EAs at FundedNext at all.

The5ers
Founded 2016 · MT5, cTrader, TradingView. No MT4
The strictest third-party position of the six. Prohibited practices include "EA from a third party, where other traders have the same trades open (copy trading)" and:
That clause carries no qualifier. A closed-source commercial EA fails it outright. On the published wording, this is a self-coded-EA-only firm.
Stop losses must be visible in the trading platform. That rules out any EA holding its exit internally rather than placing it with the broker — a common design in commercial grid EAs, and one a sales page will not tell you about.
Drawdown triggers on account equity, so floating losses count. The Hyper-Growth product has no daily breach at all — instead a 3% pause that closes trades and disables the account until the next day. A pause is survivable; a breach is not. Grid and martingale are not addressed anywhere in the published rules.

Alpha Capital Group
Founded November 2021 · MT5 only for EAs. No MT4
Alpha Capital should not be presented as an EA firm, and we will not present it as one.
Pre-approval is mandatory — the EX5 file is emailed to support before use. A No Group Trading rule applies: "If multiple traders are identified using the same EA and placing identical trades, this will be treated as a breach."
Two further rules constrain EAs without naming them. The Max Risk Rule caps floating drawdown on any single asset at 3%, 2% or 1% depending on account size — a hard limit on grid and basket strategies. The 2-minute average trade duration rule requires the average duration of all trades to exceed two minutes, with at least half of profit coming from trades held longer than that.
Daily limits apply to "balance or equity, whichever is greater", and "breaches are always applied based on open trades (unrealised losses)."

E8 Markets
Founded 2021 · MT5, cTrader, TradeLocker, MatchTrader. No MT4
The most permissive wording of the six, with a sharp catch.
Martingale is explicitly permitted: "Yes, we allow our traders to utilize the martingale strategy." Grid is not addressed.
The drawdown structure deserves attention. Maximum drawdown trails closed balance, which is favourable to a strategy carrying floating losses. But the daily limit breaches on "equity or balance", so it is equity-based and can breach intraday. That combination specifically punishes the grid and martingale EAs the firm nominally allows.
Operational caps: 50 lots per ticket, 100 open orders, 2,000 server requests and 2,000 positions per day. E8's explainer articles and product pages quote different drawdown percentages, and the amount is customisable at checkout — so we publish a range rather than a single figure.

Instant Funding
Launched June 2022 · MT5, cTrader, Match-Trader. No MT4
The boundary of "publicly available" is not defined, and there is no whitelist or approval route. A privately coded EA is fine; a bought one is not.
Grid is prohibited by name: "Placing buy and sell orders at fixed intervals, relying solely on price fluctuations rather than informed analysis." Martingale is "allowed for all challenges", though on funded accounts "repeatedly doubling lot sizes after losses is not permitted" — and "martingale activity is evaluated without consideration of the symbol or asset involved", which catches basket EAs trading several pairs.
Daily loss counts floating profit and loss, measured from "whichever is higher between your Balance and Equity at 17:00 EST".

Allowed Is Not The Same As Safe
Each of these firms sells access to a simulated account with a pass condition attached. Their exposure is that many traders pass at once running the same strategy, because a funded account is a real liability. That is why the restrictions cluster around other people running the same EA rather than around the EA itself.
It produces a rule nobody advertises: a commercial EA gets riskier the better it sells. The more copies in circulation, the more likely two customers of the same firm run identical trades — and at FTMO that risks the funded account being denied after a pass, at E8 Markets it "may lead to the termination of your account", at Alpha Capital it is a No Group Trading breach, and at The5ers and Instant Funding it was never permitted in the first place.
A vendor advertising an EA as "prop firm ready" has an interest in selling as many copies as possible. The buyer's interest runs the other way. Both cannot be served.
Three things to check before you buy anything.
The platform, before the rules. If your EA is MT4-only, your choice is FTMO or FundedNext and the question stops there.
How drawdown is measured, not just the headline percentage. A 10% limit on closed balance and a 10% limit on equity including floating losses are different rules, and grid EAs live or die on the difference. All six count floating losses against the daily limit. The four drawdown types, explained.
Whether the EA places its stop loss with the broker. The5ers requires a visible stop-loss order. Several commercial EAs hold their exits internally instead, and a sales page will not tell you which.
What We Have Actually Tested
We do not recommend Expert Advisors for prop firm challenges. We test specific configurations against specific firms' published rules and publish what happened, including when it is unflattering. The method is set out in full in our testing methodology, which is free and needs no email address.
A conformance test is not a review and produces no verdict on the Expert Advisor. It answers one question: would this configuration, exactly as the developer supplies it, have stayed inside this firm's limits?
Perceptrader AI — developer's FTMO set file
Result: −4.16%, maximum equity drawdown 11.15%, profit factor 0.862.
It never approached FTMO's 10% profit target, so it fails on that ground alone. It stayed inside the 2-Step static loss limit by £190. Against the 1-Step limit it does not: the peak end-of-day balance of £10,343.70 sets a floor of £9,343.70, and equity reached £9,190.13 — a breach of £153.57.
The set file guards FTMO's daily limit at 4.5% but leaves the EA's own overall drawdown protection switched off, so nothing in the configuration was watching the 10% limit. Our full review of Perceptrader AI covers the standard configuration, which is a different set of pairs and settings.
Forex Flex EA — developer's FTMO set file
Result: +1.60% against a 10% target — and it stopped trading after five weeks and never resumed.
The supplied set file carries a 30-day maximum trading period that FTMO no longer imposes. Before it stopped, it multiplied its position size by up to eleven times on finding itself behind target with the window closing. That escalation is documented in the vendor's own user guide.
Run the same strategy with the prop firm module switched off — at a lower risk setting than the prop firm file uses — and it holds a losing basket for 561 days to a 27% equity drawdown, which is a failed challenge several times over. The only thing that kept the supplied configuration inside FTMO's loss limits was that it switched itself off.
Twelve trades is far below the 100 closed trades we require before drawing any conclusion about a strategy, and we draw none. What the test establishes is how a developer-supplied prop firm configuration behaved against one firm's published rules — and the 30-day cut-off and the position-size escalation are properties of the settings file, readable in it before a single trade is placed.
Prop Firms And EAs, Answered
Which prop firms allow Expert Advisors?
On their own published rules as at 17 September 2026, FTMO and E8 Markets permit third-party EAs with conditions, FundedNext permits them as a paid add-on with a distinct strategy requirement, and The5ers, Alpha Capital and Instant Funding do not permit commercially-bought EAs at all.
Can I use an EA on FTMO?
Yes, EAs are permitted. FTMO's own warning is that using a third-party EA risks being denied the funded account under the maximum capital allocation rule if other traders are running the same one. That rule caps total allocation at $400,000 per trader or strategy.
Which prop firms offer MetaTrader 4?
Of the six we checked, FTMO and FundedNext. The other four offer MT5 and newer platforms only.
Is grid trading allowed at prop firms?
FundedNext and Instant Funding prohibit it by name. FTMO, The5ers, Alpha Capital and E8 Markets do not address grid trading in their published rules — which is not the same as permitting it.
Is martingale allowed?
FundedNext, E8 Markets and Instant Funding permit it explicitly, with conditions at Instant Funding on funded accounts. The other three do not address it.
Do floating losses count toward the daily loss limit?
At FTMO, FundedNext, The5ers, Alpha Capital, E8 Markets and Instant Funding, yes. FTMO's wording is that "the calculation includes both the results of closed positions and the floating P/L of open positions, as well as commissions and swaps." This is the rule that catches grid and averaging EAs most often.
Will a prop firm ban me for using a popular EA?
Several state they may. E8 Markets says multiple users running the same EA "may lead to the termination of your account." Alpha Capital treats it as a No Group Trading breach. FTMO warns it may deny the funded account. FundedNext bans five named commercial EAs outright.
Our position. We have no affiliate or commercial relationship with any of the six prop firms named on this page, and none with the developer of Forex Flex EA. Nothing about those firms or that product was supplied, reviewed or approved by them.
One disclosure. We have an affiliate relationship with ValeryTrading, the developer of Perceptrader AI, approved on 17 August 2026. Our review of that product, and its verdict, were published before that relationship existed and were reached without reference to it. The FTMO settings file tested above was supplied by ValeryTrading, after the relationship began. We publish that here so you can weigh the result knowing where the material came from — it failed the test either way.
Every rule was read from the firm's own website, help centre or terms, and is quoted rather than paraphrased wherever the wording matters. Prop firm rules change without notice. We re-verify this page quarterly and date every change.
Where a firm's own documents contradict each other, we say so and publish neither side as fact. There are three such conflicts on this page, at FundedNext, The5ers and Instant Funding.
Trading carries risk. Nothing on this page is financial advice or a recommendation to buy any product or use any firm.
