Expert Advisors (EAs) available on SYSTEMTRADE.COM are compatible with MT4 (MetaTrader 4).
MT4 is software that runs on your computer and serves as a trading platform provided by FX brokers.
This platform allows you to trade in the FX markets.
To run EAs from SYSTEMTRADE.COM, configure the following 3 settings in MT4. This is a one-time setup.
- Allow WebRequest
Go to Tools → Options → Expert Advisors tab, check “Allow WebRequest for listed URL” and add the following (copy & paste):https://sys-tre.com/ - Allow automated trading
Check “Allow automated trading” in the same tab - Allow DLL imports
Check “Allow DLL imports (only for trusted applications)”
→ Click OK to save. EAs will not run without these settings.
What is MT4?
To run an EA properly, you need to apply the EA to a chart with the specified currency pair and timeframe, then start automated trading.
Chart Display
MT4 graphically displays forex rates and prices of other financial instruments. By viewing these charts, you can understand price movements and trend patterns.
Trade Orders
As a trading platform, it naturally allows you to place trade orders. For example, you can place “buy orders” to purchase or “sell orders” to sell specific currency pairs (e.g., EUR/USD). To place orders, you need to specify the trade size (order volume) and entry point (price).
Technical Analysis
MT4 provides various technical indicators and graphical tools that you can use to analyze price movements and trends. For instance, you can utilize indicators such as moving averages and the Relative Strength Index (RSI).
Automated Trading
MT4 includes functionality for creating and executing EAs (Expert Advisors). This allows you to automatically execute trades based on predefined rules. This is the feature you’ll use for EAs downloaded from our site.
Backtesting
MT4 also allows you to test trading strategies using historical data. This enables you to evaluate trading performance based on past data and verify the accuracy of future predictions.

Summary
MT4 remains the most widely used trading platform for automated EA trading.

Frequently Asked Questions about MT4 EA Setup
What is an Expert Advisor (EA) for MT4?
An Expert Advisor (EA) is an automated trading program that runs inside MT4. It monitors the market, opens and closes trades based on pre-programmed rules, and operates 24/5 without manual intervention. EAs are written in MQL4 and installed as .ex4 files.
How do I install an EA on MT4?
Copy the .ex4 file into the MT4 data folder under MQL4/Experts, then restart MT4 or right-click the Navigator panel and select Refresh. Drag the EA onto a chart, check “Allow automated trading” in the EA settings, and ensure the AutoTrading button at the top of MT4 is enabled (green).
What settings should I configure for an EA?
At minimum, configure the lot size (or risk percentage), stop loss, take profit, and magic number. The magic number uniquely identifies trades from this EA and is essential when running multiple EAs on the same account. Always review the EA documentation for recommended parameter values.
Do I need a VPS for EA trading?
A VPS (Virtual Private Server) is strongly recommended. It keeps MT4 running 24/5 even if your local PC is off, eliminates latency from your home internet connection, and prevents missed trades due to power outages. Most brokers offer discounted VPS services for active accounts.
How do I know if my EA is working correctly?
Check the Experts tab at the bottom of MT4 for activity logs. If the EA is running, you will see timestamped messages. Verify that trades appear in the Terminal tab when expected. Run a Strategy Tester backtest on the same settings to confirm the logic matches your live results.
What should I do if my EA is not opening any trades?
Check that: (1) AutoTrading is enabled (green button), (2) the EA is attached to the correct chart and timeframe, (3) “Allow live trading” is checked in the EA properties, (4) the account has sufficient margin. Review the Experts log for error codes — code 130 means invalid stops, code 4 means server is busy.
