1. FTMO Rules Every EA Must Follow

Before writing a single line of code, understand the rules. FTMO enforces these limits automatically — if your EA violates any of them, the challenge is failed regardless of profit.

These rules apply to the standard FTMO Challenge (10% evaluation, 5% verification). FundedNext, The5ers, and other prop firms have similar but slightly different parameters — we handle all of them.

2. Best Strategies for FTMO EAs

Not all strategies are suitable for prop firm challenges. The goal is steady, consistent growth — not maximum returns. These strategy types have the highest pass rate in our experience.

3. Building an FTMO-Compliant EA

An FTMO-compliant EA is built with three mandatory layers: risk control, trade management, and compliance monitoring.

4. FTMO Compliance Code Examples

Here are the critical MQL5 code blocks that handle FTMO compliance in our EAs.

Daily Loss Limit

// Daily loss limit check
double CalculateDailyLoss() {
    double startBalance = GetStartBalance();
    double currentEquity = AccountInfoDouble(ACCOUNT_EQUITY);
    double dailyLossPct = (startBalance - currentEquity) / startBalance * 100;
    return dailyLossPct;
}

bool CheckDailyLossLimit() {
    double dailyLoss = CalculateDailyLoss();
    if(dailyLoss >= 4.5) {  // 4.5% threshold (FTMO max = 5%)
        CloseAllPositions();
        DisableTradingForDay();
        Print("Daily loss limit reached: ", dailyLoss, "%");
        return false;
    }
    return true;
}

News Blackout Filter

// News filter using live economic calendar
bool IsNewsBlackout() {
    datetime now = TimeCurrent();
    // 3 min before and after each event
    for(int i = 0; i < ArraySize(newsEvents); i++) {
        if(now >= newsEvents[i].time - 180 &&
           now <= newsEvents[i].time + 180) {
            return true;  // In blackout window
        }
    }
    return false;
}

bool CheckNewsBlackout() {
    if(IsNewsBlackout()) {
        Print("News blackout active — skipping trade");
        return false;
    }
    return true;
}

These code blocks are part of our standard FTMO-compliant EA template. We include them in every prop-firm EA build.

5. Common FTMO EA Mistakes

After auditing hundreds of EAs for prop firm compliance, these are the most common failure reasons.

• Over-optimised backtest: A perfect-looking curve that fails in forward test. Solution: walk-forward validation.
• No daily loss monitor: EA trades through a losing day and hits the 5% FTMO limit. Solution: hard-coded daily P&L tracker.
• Ignoring spread widening: EA enters during high-impact news, gets terrible fills. Solution: spread gate + news filter.
• Too many trades: High-frequency strategies create consistency score issues. Solution: max trades-per-day parameter.
• Wrong position sizing: Fixed lot sizes that don't scale with account growth. Solution: %-based risk per trade.
• No broker calibration: EA assumes symbol names and execution modes that don't match FTMO's MT5 setup.

6. Making Your Existing EA FTMO-Ready

Have an EA already built that you want to run on FTMO? We can add the compliance layer without rewriting the trading logic. The audit and retrofit process covers:

• Review existing code for rule violations (martingale, grid, hedging)
• Add daily loss limit and max drawdown monitors
• Implement news blackout windows
• Add consistency score tracking
• Calibrate position sizing for FTMO account sizes ($10K, $25K, $50K, $100K, $200K)
• Test on FTMO demo server before deployment
