How to configure an Expert Advisor on a funded account: step-by-step guide

You have a tested EA and want to use it in an FTMO, MyForexFunds, E8 or any other prop firm challenge. The most common mistake: loading the same configuration you use on your personal account and expecting it to work. Funded account rules change everything. Here is the complete process.

Step 1: read the firm's rules before touching anything

Before opening MetaTrader, read the firm's terms line by line. The most common restrictions that invalidate accounts:

• Maximum daily drawdown. Usually 4–5% of balance. If your EA has days with 3% intraday drawdown, you are too close to the limit.
• Maximum total drawdown. 8–10% of starting balance. With trailing drawdown (FTMO in challenge phase), this number moves as your equity rises.
• News restriction. Many firms prohibit having open trades 2–5 minutes before and after high-impact news (NFP, rate decisions, CPI). Check if your firm requires this.
• Weekend restriction. Some firms do not allow holding trades open during the Friday market close.
• Consistency rule. A single day cannot represent more than 30–50% of total profit at many firms.
• Minimum trade duration. Some firms require a minimum open position time (anti-scalping). Verify if there are HFT or latency arbitrage restrictions.

Step 2: calculate the maximum risk per trade

With the rules clear, calculate the risk you can take per trade. The conservative formula:

• Maximum permitted daily drawdown: 5%
• Maximum consecutive losses you accept in a day: 5
• Maximum risk per trade: 5% ÷ 5 = 1% per trade

For a $100,000 challenge, 1% = $1,000 maximum risk per trade. In most EAs, this translates to lots. With a 20-pip stop on EURUSD and a pip value of ~$10/pip per standard lot, $1,000 risk = 5 standard lots.

If the EA has historical consecutive losing streaks of more than 5 trades (check the backtest), reduce risk to 0.5% per trade for additional margin.

Step 3: configure the news filter

If the firm prohibits trading during news, you need the EA to close positions and block new entries during those windows. Two options:

Option A — EA's internal filter. Many professional EAs have an integrated news filter parameter. In Master of Liquidity EA, enable the NewsFilter = true parameter and configure MinutesBeforeNews and MinutesAfterNews according to your firm's requirements (generally 5 minutes before and 5 after is sufficient).

Option B — External tool. If the EA has no built-in filter, use a news management script that closes positions and blocks the EA before releases. Free versions are available on the MQL5 Market.

Step 4: configure trading hours

If your firm prohibits holding positions over the weekend, enable the pre-Friday close parameter in the EA. Recommended window: close all open positions between 21:00 and 22:00 GMT on Friday, before Forex market close.

If the EA lacks this parameter, create a scheduled task on the VPS that runs a close script on Fridays at 21:30 GMT.

Step 5: configure parameters in MetaTrader 5

Recommended EA configuration before activating on the challenge:

Step 6: run on demo with the same conditions first

Before activating the EA on the real challenge account, run it for 5–7 days on a demo account with the same balance as the challenge. Verify:

• Daily drawdown never exceeds 3% (safety margin above the firm's limit)
• News filter activates correctly on high-impact releases
• Positions close on Friday as configured
• Lot sizes correspond to the configured risk (review trade history)

Step 7: monitoring during the challenge

Once the challenge is active, review daily:

• Current equity vs. daily drawdown limit. If by 14:00 you already have 2.5% drawdown, consider manually pausing the EA for that day.
• Cumulative total drawdown. If you have 5% total drawdown and the limit is 10%, you are aware you have 5 more points of margin.
• Number of trades for the day. If the consistency rule applies, ensure no single day accumulates too high a percentage of total profit.

A VPS with MetaTrader 5 always active is essential. Any disconnection can leave positions open without protection during news or over the weekend.

Mistakes that destroy the challenge

• Activating the EA with the same risk as on a personal account (usually 2–3%, too high for prop firm)
• Not configuring the news filter and having a trade open during NFP
• Forgetting that FTMO's drawdown is trailing: each new equity high raises the elimination level
• Using a VPS with high latency that executes orders late during volatile periods
• Not reading the consistency rule and having an exceptional day that invalidates the payout
