• Most major prop firms accept EAs (Expert Advisors — automated trading scripts).
  • HFT (high-frequency trading, sub-second activity) is banned across the board.
  • Account-to-account copy trading is also universally prohibited.
  • In our review, The5%ers and FTMO are the strongest picks for EA-led workflows.

EAs are increasingly common on prop accounts, but the rule set is narrower than at retail brokers. In practice, the gap between “allowed automation” and “prohibited automation” is where most rule breaches happen.

EA-friendly firms

Top picks for automated workflows:

  • The5%ers — a veteran option; its one-step Hyper Growth keeps the evaluation short for EA testing.
  • FTMO — industry standard with clearly published EA rules.
  • FundedNext — multiple plan variants, EAs explicitly permitted.
  • FundingPips — low fees make it cheap to test new EAs.

Universal restrictions

By contrast, the following are banned almost everywhere and easy to trip on accidentally:

  • HFT (sub-second order activity).
  • Copy trading from external signal sources.
  • Account-to-account hedging.
  • Arbitrage strategies (latency or pricing).
  • News-window trading, typically a two-minute buffer pre and post major releases.

That said, the restrictions are well-published and consistent. Once your EA is configured to respect them, the major firms are workable. In short: read the prohibited-practices section before deploying any system.

FTMO — the peace of mind of the largest name in the industry

The industry standard, with 11 years of operation (since 2015), and the EA rules are clearly published, so you can check an automated system against them before you pay.

The free trial lets you test everything at no cost, and the 2-Step Challenge fee is refunded with your first payout after passing (no refund if you fail). See the FTMO free trial guide.

The5%ers — a veteran option for EA testing

Operating since 2016. Its one-step Hyper Growth keeps the evaluation short, which is useful when you are putting a new EA through its paces. Note: on 2026-08-01 this site re-rated The5%ers from High to Low trust (★4.6→3.3) after the firm itself acknowledged payout delays in March 2026; if you use it, keep the ticket small and confirm your first payout arrives before scaling up.
