How to set up an EA for a prop firm challenge
To run an EA on a prop firm challenge, first check that the firm allows it: several large firms ban third-party EAs or allow them only as risk managers. Then size trades so a normal losing streak stays inside the daily limit, set the EA’s guards below the firm’s limits on the same basis and clock, and follow its news and weekend rules.
An EA can follow risk rules more strictly than a person can, which is why traders use them on challenges. It can also fail a challenge in minutes if its settings ignore the firm’s rules. These seven steps set up an EA for a prop firm challenge so the firm’s limits are never the first thing that stops it.
1. Check the firm allows your EA
This is the step most traders skip, and the rules differ more than the marketing suggests:
| Firm and plan | Are EAs allowed? | Watch out for |
|---|---|---|
| FTMO | Yes | Trading the same third-party EA strategy as many other traders can lead to a funded account being refused; limits of 200 open orders and 2,000 positions a day |
| FundedNext Stellar 2-Step | Third-party EAs on accounts under $50K, with a paid add-on, on MT4 or MT5 | Accounts of $50K and above are manual only; EAs built to pass challenges and grid trading are banned |
| The5ers High Stakes | Only your own software, with written approval first | Third-party EAs are not allowed |
| FundingPips 2-Step Standard | Third-party EAs only as trade or risk managers | Your own EA is allowed if you can prove it is yours, for example with the source code |
| E8 Markets | Yes, on E8 One, Pro and Signature, not Zero | Not allowed when several users run the same trades |
| Alpha Capital (Alpha Pro) | Only pre-approved risk-management or trade-assistance tools, on MT5 | Fully automated EAs are not allowed; there is a two-minute average trade duration rule |
Rules as published on 6 November 2026. Firms change them often, so read the current terms before you pay. Our prop firm EA rules comparison covers each firm in more detail.
2. Rule out banned strategies
Even where EAs are allowed, firms ban styles that exploit the simulated environment or the firm itself. The most common bans are:
- high-frequency trading and flooding the server with requests (E8 counts more than half of trades closing within a minute as high-frequency)
- latency arbitrage and other arbitrage
- tick scalping
- hedging or opposite positions across accounts
- copy trading, and the same trades run by many users
- grid trading, banned at FundedNext
- news bracketing, banned at The5ers
If an EA works by doing any of these, it is the wrong EA for that firm, whatever its results.
3. Size trades to the daily limit
Work backwards from the daily limit. Set a guard below it, then choose a risk per trade that a normal losing streak can’t push through. On a $100,000 account with a 5% daily limit and a guard at 4% ($4,000):
| Risk per trade | Risk in money | Full losses in a row to reach the guard |
|---|---|---|
| 0.25% | $250 | 16 |
| 0.5% | $500 | 8 |
| 1% | $1,000 | 4 |
| 2% | $2,000 | 2 |
Then check the EA’s worst losing streak in its live record and backtest; the guard should sit well beyond it. Turn the risk into a lot size for each stop with the position size calculator.
4. Set the daily and overall guards
- Daily guard on equity at about 80% of the daily limit, reset at the firm’s reset time: 00:00 CE(S)T at FTMO, 00:00 GMT+2 at Alpha Capital.
- Same basis as the firm. Some firms set the floor from the day’s starting balance, others from the higher of balance and equity; the guard should use the same reference.
- Overall guard below the maximum loss floor. On a trailing maximum, move it up as the floor rises.
- Close everything when a guard triggers, and stop the EA for the day, not just block new entries.
Our guide to prop firm daily drawdown shows how each method works with examples, and the prop firm drawdown calculator gives today’s floor and a suggested guard level.
5. Follow the news and holding rules
| Firm | News rule (funded accounts unless stated) | Holding rule |
|---|---|---|
| FTMO Standard account | No trades opened or closed from 2 minutes before to 2 minutes after restricted news | Close positions before market breaks of more than two hours; evaluation and Swing accounts are exempt |
| The5ers High Stakes | No orders from 2 minutes before to 2 minutes after high-impact news | Not covered here |
| E8 One | No opening or closing trades from 5 minutes before to 5 minutes after high-impact news | Not covered here |
| Alpha Capital | No opening or closing trades from 5 minutes before to 5 minutes after listed news | No weekend holding on funded accounts |
| FundingPips | Trading news on purpose is prohibited; on Master accounts, profit from trades 5 minutes either side of restricted news is deducted unless the trade opened 5 or more hours earlier | Master account positions close each day unless you buy the Swing add-on |
| FundedNext | On funded accounts you keep 40% of the profit from trades within 5 minutes of high-impact news | Not covered here |
Several firms restrict closing as well as opening during the window, so an EA should close or protect trades before it starts. Our guide to the EA news filter covers the settings that matter.
6. Rehearse on demo first
Run the EA on a demo or free trial with the same leverage, symbols and settings as the challenge, for long enough to see a losing run. Check that symbol names match the firm’s server, that the guards trigger where you expect, and that the EA keeps running on a forex VPS. If it opens no trades, our EA not opening trades guide covers the usual causes, and set files explained shows how to load the right settings.
7. Check the account every day
Before each session, note today’s floor and the room left, and compare them with the firm’s dashboard. Watch for what the EA can’t see: a release its news filter missed, a trade held into the reset, or a trailing maximum that has moved up.
EA for prop firm challenge FAQ
Can I use an EA on a prop firm challenge?
Often, but not everywhere. FTMO and E8 Markets allow EAs within their rules. FundedNext allows third-party EAs only on smaller Stellar accounts with an add-on, FundingPips and Alpha Capital allow them mainly as trade or risk managers, and The5ers’ High Stakes allows only your own approved software.
Can I use the same EA on several prop firm accounts?
Check first. FTMO and E8 Markets watch for the same trades across accounts or users, and many firms ban copy trading and hedging across accounts.
What risk per trade should an EA use on a challenge?
Low enough that a normal losing streak can’t reach the daily guard. On a $100,000 account with a 4% guard, 0.5% per trade allows eight full losses in a row.
Do I need a VPS for a prop firm EA?
Yes, if it must run through every session without interruption. An EA only trades while MetaTrader is running and connected, and a VPS close to the firm’s server keeps delays low.
Will an EA pass a challenge for me?
No tool can promise that. A good setup makes the EA follow the firm’s rules exactly; the market decides the rest.
Risk warning. Trading forex and CFDs on margin carries a high risk of losing money, and most challenges are not passed. The tables on this page are arithmetic examples, not results of any EA. Prop firm rules change often; read the firm’s current terms before you buy.
