How to Use an MT5 Expert Advisor on Prop Firm Accounts — Complete Guide

<h2>Do Prop Firms Allow Expert Advisors?</h2>

<p>The majority of major prop firms — including FTMO, Funded Next, E8 Funding, Apex, TopStep and The5ers — explicitly allow expert advisors. The key is understanding what "allow EAs" actually means in practice.</p>

<p>Permitted: EAs that execute your strategy with defined entries, exits, stop losses and take profits. EAs that manage risk, enforce position limits, or automate discipline. EAs that trade your edge systematically.</p>

<p>Prohibited by most firms: High-frequency scalping EAs that hold positions for seconds. Latency arbitrage (exploiting price discrepancies between brokers). Martingale and grid strategies that increase position size after losses. Copy trading directly from another account (check firm-specific rules).</p>

<p>Always read the specific prop firm rules before deploying any EA. When in doubt, contact their support team directly before the challenge — not after a trade is flagged.</p>

<h2>Installing an EA in MetaTrader 5</h2>

<p>Step 1: In MT5, click File → Open Data Folder. Navigate to MQL5 → Experts. Copy your .ex5 file into this folder.</p>

<p>Step 2: In MT5, go to View → Navigator (or press Ctrl+N). Right-click Expert Advisors and select Refresh. Your EA should now appear in the list.</p>

<p>Step 3: Open a chart for the instrument you want to trade. Drag the EA from the Navigator panel onto the chart.</p>

<p>Step 4: In the settings window, click the Common tab and confirm Allow Live Trading is checked. Configure your inputs in the Inputs tab.</p>

<p>Step 5: Confirm the Algo Trading button in the MT5 toolbar is green (active). Without this, the EA cannot open trades even if it is attached to the chart.</p>

<h2>Configuring Risk Settings for Prop Firm Rules</h2>

<p>When attaching an EA to a prop firm account, always adjust these settings to match the firm's rules:</p>

<p><strong>Daily loss limit:</strong> Set the EA's maximum daily loss to 1% below the firm's limit. If FTMO allows 5% daily loss, set the EA to halt at 4%. This buffer prevents the EA from accidentally triggering the firm's rule due to timing differences in P&L calculations.</p>

<p><strong>Maximum drawdown:</strong> Same principle — set 1-2% below the firm's maximum drawdown rule.</p>

<p><strong>Position size:</strong> Start with 0.5% risk per trade for challenges. You can scale up conservatively once the funded account is active.</p>

<p><strong>Trading hours:</strong> Configure session filters to match the firm's rules and your tested strategy hours. Not all EAs trade well in all sessions.</p>

<h2>What AlphaBot Pro Does Specifically</h2>

<p>AlphaBot Pro is designed specifically for prop firm trading. The EA includes a built-in daily loss ceiling that closes all positions and halts new trades when triggered, a consecutive loss pause that prevents revenge trading patterns, a daily profit lock that stops trading when the day's target is reached, ATR-based position sizing that adjusts to current market volatility, and a session filter that trades only during specified hours.</p>

<p>The license system uses an online validation checked every 6 hours, so the EA works correctly across all prop firm MT5 platforms that allow WebRequest.</p>
