Key Takeaways

1. What Is a Forex EA?

A Forex EA (Expert Advisor) is a piece of software that you attach to a chart in MetaTrader 4 (MT4). Once attached, it can open, manage, and close trades based on a programmed set of rules. Traders often call it a trading robot because it works even when you are away from your screen, sticking to its logic without emotions.

• Benefits at a glance
  • Trades around the clock on your behalf
  • Removes fear and greed from decisions
  • Follows a repeatable plan, making back-testing possible

2. Why Trade with Forex EA MT4?

Forex EA MT4 is built to run automatically on the M15 chart. Let us look at what makes it stand out.

2.1 Two Trading Modes

You can switch modes without reinstalling the EA. Many traders like to start in Conservative mode, then move to Acceleration once they feel comfortable.

2.2 Currency Pairs & Timeframes

• GBP pairs (GBPUSD, GBPCAD, GBPJPY)
• Major pairs (EURUSD, USDJPY, AUDUSD, USDCAD, USDCHF)
• Timeframe: 15-minute chart (M15)

Testing shows that spreads on these pairs are often tight, which keeps the cost of entering trades low. Running on the same timeframe across all pairs also makes performance easier to track.

2.3 Risk Control Features

1. Max Spread Filter – Stops entries when the spread widens during news events.
2. Daily Drawdown Limit – Once the account drops by a user-defined %, the EA pauses for the day.
3. Lot Size Steps – You can set a lot step of 0.01 to scale positions smoothly.

3. Setting Up Forex EA MT4 on MetaTrader 4

3.1 Download & Installation

1. Download the .ex4 file from the vendor’s site.
2. Open MT4 → File → Open Data Folder → MQL4/Experts.
3. Copy the file into Experts.
4. Restart MT4 or click Refresh in the Navigator pane.
5. Drag the EA onto an M15 chart of your chosen pair.
6. Enable Algo Trading (top toolbar).

Tip: To run the EA 24/5 without keeping your computer on, consider a VPS. Many brokers provide one for free above a deposit threshold.

3.2 Input Parameters Explained

Adjust only after you fully understand each setting. An in-depth manual is normally included in the download.

3.3 Account Recommendations

• Minimum deposit: $100 (micro account).
• Recommended deposit: $500–$1,000 for smoother growth.
• Leverage: 1:100 to 1:500 helps the EA set stops further away without margin issues.
• Broker type: ECN with spreads below 1 pip on EURUSD and GBPUSD.

4. Back-Test Results & Live Performance

Back-tests give you an idea of past behavior; live results confirm it works under real trading conditions.

4.1 Back-Test Methodology

• Data: Tick-by-tick model, 99 % quality (Dukascopy).
• Period: Jan 2015 – Dec 2023.
• Spread: Variable, average 0.8 pip on GBPUSD.
• Risk: Fixed lot 0.01.

Note: Past results don’t guarantee future profit, but they show whether the logic makes sense over many market cycles.

4.2 Sample Back-Test on GBPUSD M15

Chart below:

4.3 Forward Testing on a Demo Account

• Platform: IC Markets demo
• Period: Jan – Mar 2024
• Pairs: GBPUSD, EURUSD, USDJPY
• Result: +4 % with max drawdown 2 %.

You can replicate this by running the EA on a free demo first. It lets you build confidence before risking real money.

5. Money Management with Forex EA MT4

5.1 Lot Size & Scaling

A common rule is 0.01 lot per $200 balance. That keeps risk at about 1 % per trade. When your balance doubles, you can either:

• Keep the lot fixed (less risk), or
• Double the lot to 0.02 to keep the same percentage risk.

5.2 Handling a String of Losses

Even a high-win-rate robot can face losing streaks. Prepare by:

1. Setting a daily drawdown stop.
2. Reducing lots after four consecutive losses.
3. Reviewing economic news—if high-impact events loom, pause the EA.

5.3 Choosing a Broker

Criteria checklist:

• VPS near broker’s data center (latency < 5 ms).
• True ECN or raw spread account.
• Ethical regulation (ASIC, CySEC, FCA).

6. Tips for Day-to-Day Use

6.1 When to Switch Between Modes

Switch in the Inputs tab; MT4 will reload the EA with new risk limits.

6.2 Updating the EA

Vendors release updates every few months to adapt to market changes. Steps:

1. Download the new .ex4.
2. Replace the old file in MQL4/Experts.
3. Restart MT4.
4. Check BrandNewVersion-X.X message in the Experts tab.

6.3 Keeping a Trading Journal

Record:

• Date & time of each trade
• Mode used
• Lot size
• Result in pips and $
• Notes (spread spike, slippage)

A simple spreadsheet works. Over time, patterns such as “better on GBPUSD” become clear.

7. Common Questions

Q1. Can I run Forex EA MT4 on MetaTrader 5?No. The code is compiled for MT4 only. Running on MT5 would need a fresh build by the developer.

Q2. Does it use martingale?No. Each order stands alone with its own stop and target.

Q3. How many charts do I need open?One per pair, all set to M15. So, if you trade five pairs, open five charts.

Q4. What happens if I turn off my PC?The EA stops. Use a VPS to keep it running.

8. Final Thoughts & Next Steps

Forex EA MT4 gives new and seasoned traders a tool to automate entries on the M15 chart, manage risk with daily limits, and pick between growth or stability modes. By starting on a demo, sticking to 0.01 lots, and recording every trade, you can learn how this Forex EA behaves before moving to a live account.
