Best EA Settings for Prop Firm Challenges (FTMO, E8 Markets)

Prop firm challenges are the fastest way to trade with serious capital without risking your own money. But most traders fail — not because their strategy is bad, but because their EA settings do not respect the strict rules these firms enforce. In this guide, we will show you exactly how to configure your Expert Advisor to pass challenges from FTMO, E8 Markets, and other major prop firms.

Understanding Prop Firm Rules

Before configuring anything, you need to understand the rules. Every prop firm has three primary constraints:

• Maximum Daily Loss: Typically 5% of the account balance. If you lose more than this in a single day, you fail.
• Maximum Total Drawdown: Usually 10% of the starting balance. Your equity can never drop below this threshold at any point during the challenge.
• Profit Target: Usually 8-10% for Phase 1 and 5% for Phase 2. You must hit this target within the time limit (usually 30 days).

These rules mean your EA must be conservative enough to never breach drawdown limits, yet aggressive enough to reach the profit target in time. Finding this balance is the key to passing.

FTMO Challenge Settings

FTMO is the most popular prop firm, with strict rules but a well-defined process:

• Daily Loss Limit: 5% ($5,000 on a $100K account)
• Max Drawdown: 10% ($10,000 on a $100K account)
• Profit Target Phase 1: 10%
• Profit Target Phase 2: 5%
• Time Limit: 30 calendar days per phase

Recommended EA Settings for FTMO

• Risk Per Trade: 0.5% — gives you 10 consecutive losers before hitting daily limit
• Max Daily Loss Cap: 3% — stops trading for the day at 3%, well below FTMO's 5% limit
• Max Open Trades: 2 — limits exposure and prevents compounding losses
• Stop Loss: ATR-based (1.5x multiplier) — adaptive to volatility
• Take Profit: 2:1 risk-reward ratio — needs only 40% win rate to be profitable

E8 Markets Settings

E8 Markets has tighter rules than most firms, requiring more conservative settings:

• Daily Loss Limit: 4% (stricter than most firms)
• Max Drawdown: 8% (EOD dynamic drawdown)
• Profit Target Phase 1: 8%
• Profit Target Phase 2: 4%
• Time Limit: Unlimited

Recommended EA Settings for E8 Markets

• Risk Per Trade: 0.4% — tighter daily limit demands lower risk per trade
• Max Daily Loss Cap: 2.5% — well below E8's strict 4% daily limit
• Max Open Trades: 2
• Stop Loss: ATR-based (1.5x multiplier)
• Take Profit: 2:1 risk-reward ratio

Universal Prop Firm EA Rules

Regardless of which prop firm you are targeting, follow these universal principles:

1. Always Risk Less Than the Maximum

If the daily loss limit is 5%, cap your EA at 3%. If the max drawdown is 10%, design your system to never exceed 6-7%. This buffer protects you from unexpected volatility, slippage, and the compounding effect of consecutive losses.

2. Use a News Filter

High-impact news events (NFP, FOMC, ECB decisions) create extreme volatility that can blow through stop losses. Configure your EA to stop trading 30 minutes before and after major news releases. This single setting prevents most catastrophic loss days.

3. Limit Correlation Risk

If your EA trades multiple pairs, be aware of correlation. EURUSD and GBPUSD often move together. Having open positions on both means your effective risk is doubled. Either trade one pair at a time or reduce position sizes when trading correlated pairs.

4. Choose Trend-Following Strategies

For prop firm challenges, trend-following strategies (EMA crossover, MACD crossover) tend to outperform mean-reversion strategies. Trending markets produce larger wins with defined risk, which is exactly what you need to hit profit targets while respecting drawdown limits.

5. Backtest with Prop Firm Constraints

When backtesting, simulate the prop firm rules. Track maximum daily loss and total drawdown throughout the test. If your EA would have failed the challenge at any point during the backtest, it is not ready for a live challenge.

Common Mistakes That Fail Challenges

• Risking too much per trade: 2% risk per trade means just 3 consecutive losers put you near the daily limit
• No daily loss cap: Without a hard stop, one bad day can end your challenge
• Trading during news: NFP day can move EURUSD 100+ pips in seconds
• Over-trading: More trades do not mean more profit — they mean more exposure to random losses
• Ignoring the time factor: Being too conservative means you will not reach the profit target in 30 days
