EAs allowed rarely means what traders assume. And running one strategy across several of your own accounts is treated as copy trading by many firms.

Automation rules are where the gap between what a firm advertises and what its rulebook says tends to be widest. “EAs allowed” is a common headline. What it permits in practice is frequently much narrower.
This guide sets out the spectrum, the two traps that catch people, and what to ask.
Three distinct reasons, and they produce different rules.
Execution integrity. Strategies exploiting latency, pricing gaps between feeds, or simulated-fill behaviour produce results that could not be reproduced on a live account. A firm cannot underwrite those results because they are artefacts of the simulation.
Risk concentration. If a hundred traders run the same purchased EA, the firm holds one position a hundred times over rather than a hundred independent ones. Its risk model assumes diversification that does not exist.
Skill attribution. A firm is evaluating a trader. If the trades come from software the trader bought, there is nothing to evaluate.
Read a restriction against the reason behind it and its scope usually becomes clear.
| What you are doing | Typical treatment |
|---|---|
| Manual trading with indicators and alerts | Always allowed |
| EA managing trades you opened (trailing stops, partial exits, breakeven) | Usually allowed |
| EA calculating position size from your risk parameters | Usually allowed |
| EA generating entries and exits from your own logic | Varies most — check specifically |
| Commercially purchased or publicly distributed EA | Frequently prohibited |
| Copying signals from a third party | Frequently prohibited |
| High-frequency, latency or arbitrage strategies | Almost universally prohibited |
| Tick-scalping exploiting simulated fills | Universally prohibited |
Most firms advertising EA support mean trade-management automation — software that manages positions you opened. Far fewer permit signal generation, where the software decides what to trade and when.
The distinction rarely appears on the pricing page and almost always appears in the rulebook. If your strategy is fully automated, this is the single question that determines whether a firm is viable for you, and it is worth asking support directly in writing.
A useful phrasing: “Is a fully automated strategy that generates its own entries permitted, or is automation limited to managing manually opened positions?”
This one catches people who are not copy trading in any sense they would recognise.
Run the same strategy across three of your own accounts — at one firm or several — and the resulting positions are highly correlated by construction. Many firms define copy trading by the pattern rather than the intent: near-identical entries, similar timing, similar sizing across linked accounts.
You did not copy anyone. You traded your own method, several times. Under a literal reading of many rulebooks, that is prohibited account correlation, and the consequence is frequently that all affected accounts are voided rather than one.
This matters specifically because deferred-payment models make running several evaluations at once affordable, and so more people do it. If you plan to, establish the rule before you buy — not after you have three accounts running.
Traders skim the prohibited strategies section because it reads like legal furniture. It is the section most likely to end your account, and it varies more between firms than pricing does.
Read it before the pricing page. If your method appears on it, nothing else about the firm matters.
FOREXIVE publishes its evaluation and funded-account rules, including prohibited strategies, at our help centre before purchase. If you run automation, read that section first and buy second.
Automation is one of four rule areas that decide whether a firm fits your method. The others are drawdown type, consistency rules and news trading restrictions. Our guide to why traders fail evaluations covers what actually ends most attempts, and our 1-Step, 2-Step and Instant accounts list our sizes and pricing.
Can I use an EA with a prop firm?
Usually for managing positions you opened — trailing stops, partial exits, position sizing. Fully automated strategies that generate their own entries are restricted far more often. Confirm which your firm means.
Is copy trading allowed?
Copying third-party signals is frequently prohibited. More importantly, running the same strategy across several of your own accounts is often treated as copy trading by pattern, whatever your intent.
Can I run the same strategy on multiple accounts?
Sometimes, but this is the most common accidental breach among traders running several evaluations. Ask how correlation is defined before opening the second account.
Why are HFT and arbitrage strategies banned?
They exploit characteristics of the simulated environment — latency, fill behaviour, feed discrepancies — that would not exist on a live account. The results cannot be underwritten.
Are purchased EAs treated differently from ones I built?
Often, yes. A commercially distributed EA may be running on many accounts at the firm simultaneously, which concentrates risk and removes the skill the evaluation is meant to measure.
Do automation rules change after funding?
They can. Check the funded-account rulebook separately, particularly if your method depends on automation the evaluation permitted.
Trading involves substantial risk of loss. Evaluation and funded accounts described here are simulated trading environments. Nothing on this page is financial advice, and no outcome is guaranteed.
Compare every model and stage, see exactly what you pay and when, and start the challenge that suits how you trade.
