Can You Use EAs in Prop Firm Challenges?
Last updated: July 2026 | 6 min read
You built a profitable EA. Now you want to use it to pass a challenge. Here's which firms allow it and which don't.
Firms That Allow EAs
- E8 Markets — full EA support, no restrictions
- FundedNext — EAs allowed, unlimited time works well
- The5ers — HFT and EAs welcome
- Lux Trading Firm — copy trading + EAs
- Funding Pips — all automated strategies
Firms That Ban EAs
- FTMO — manual trading only
- TopStepTrader — no automation
- Earn2Trade — manual only
The Fine Print
Even firms that "allow EAs" have restrictions:
- Latency arbitrage = instant ban
- Tick scalping (100+ trades/day) = flagged
- Martingale strategies = account blown before ban
My EA Challenge Experience
I used a trend-following EA on FundedNext. Passed in 41 days with 24 trades (16 wins, 8 losses). The EA doesn't revenge trade, overtrade, or panic — that's the biggest advantage.
Important: Test your EA on demo for 3 months before using real challenge money. A buggy EA can blow an account in 1 day.
