How to Install an EA in MT5 in 2 Minutes — Step-by-Step Guide

Installing an Expert Advisor (EA) in MetaTrader 5 is a simple procedure that takes 2-3 minutes. In this article we'll go through every step in detail, with screenshots and explanations. Suitable even for those who are working in MT5 for the first time.

What Is an EA and Why Do You Need One

An Expert Advisor (EA) is a program in the MQL5 language that runs inside MetaTrader 5 and performs automatic actions: analyzes the market, opens/closes trades, or (as in the case of MyStatEA) only reads account data and sends it to an external server.

There are two types of advisors:

• Trading — open and close trades according to an algorithm. Require careful setup and testing.
• Monitoring — don't trade, only read account data (balance, positions, trades) and send it to a dashboard or Telegram. Example — MyStatEA.

Step 1 — Download the EA File

The advisor is distributed as a compiled file:

• For MT4: file with the .ex4 extension
• For MT5: file with the .ex5 extension

You can download MyStatEA for free on the mystatea.ru/ea/ page. The latest version 1.10 is available for both platforms. A screenshot of the download page is shown at the top of the article.

Step 2 — Open the Experts Folder in MT5

Launch MetaTrader 5. From the top menu, click:

File → Open Data Folder

A folder will open in Windows Explorer. Navigate to:

MQL5 → Experts

This is the folder where all advisors are stored. The full path is usually:

C:\Users\<Name>\AppData\Roaming\MetaQuotes\Terminal\<hash>\MQL5\Experts\

Step 3 — Copy the EA File

Copy the downloaded file MyStatEA_1-10.ex5 into the Experts folder. After copying, the structure should look like this:

Experts/
├── MyStatEA_1-10.ex5      ← your file
├── MACD Sample.ex5        ← example from MetaQuotes
└── ...

Step 4 — Restart MetaTrader 5

Close MT5 (File → Exit) and open it again. This is necessary so the terminal can scan the Experts folder and see the new file.

After restarting, open the "Navigator" window (Ctrl+N). In the "Advisors" section, MyStatEA_1-10 should appear:

Navigator → Advisors → MyStatEA_1-10

If the advisor isn't there, check that:

• The file is actually in the MQL5/Experts folder
• The file extension is exactly .ex5 (not .mq5 — that's source code, it won't run without compilation)
• You restarted MT5 after copying

Step 5 — Allow WebRequest for mystatea.ru

MyStatEA sends data to the server via WebRequest — a built-in MT5 function for HTTP requests. By default, MT5 blocks all external requests, so you need to explicitly allow our URL.

Open the settings: Tools → Options → Expert Advisors

In the lower part of the window, find the "Allow WebRequest for listed URL" section. Check the box and add the address:

https://mystatea.ru

Click OK. Without this setting, the advisor won't be able to send data to the dashboard — the log will show error 406 or 4014 (WebRequest not allowed).

Step 6 — Drag the EA onto a Chart and Enable AutoTrading

Open any chart (e.g., XAUUSD M5). In the "Navigator" window, find MyStatEA_1-10, hold the left mouse button and drag it onto the chart.

The advisor settings window will open. For MyStatEA, it's enough to:

1. "Common" tab: check "Allow Algo Trading" — this is MANDATORY
2. "Inputs" tab: leave the default values — all settings are hardcoded, nothing to change
3. Click OK

On the top panel of MT5, make sure the "AutoTrading" button (green circle with white arrow) is on — lit green. If off, click it.

In the upper-right corner of the chart, an icon should appear:

• 😀 Smiley face — the advisor is working
• 😠 Sad face — AutoTrading is disabled
• ❌ X mark — the advisor didn't start, check the experts log

Step 7 — Verify That Data Is Flowing

For monitoring advisors (like MyStatEA), this is the most important step. Open the dashboard at mystatea.ru/dashboard/?account=YOUR_ACCOUNT — within 5-10 seconds, data should appear: balance and equity, open positions, candlestick chart.

If there's no data, open the "Experts" tab at the bottom of the MT5 terminal (Ctrl+Tab or View → Experts menu). The advisor's logs will be there. They make it easy to understand at which step the problem is.

Common Errors and Solutions

Advisor doesn't appear in Navigator

Cause: the file is in the wrong folder, or you didn't restart MT5.

Solution: check that the file is in MQL5/Experts/, restart MT5. If that doesn't help — in Navigator, right-click "Advisors" → "Refresh".

Advisor is sad (unhappy smiley)

Cause: AutoTrading is disabled.

Solution: click the AutoTrading button on the top panel — it should light up green.

Log shows error 406 or 4014 (WebRequest not allowed)

Cause: the URL https://mystatea.ru is not in the list of allowed WebRequest URLs in MT5 settings.

Solution: Tools → Options → Expert Advisors → check "Allow WebRequest for listed URL" and add https://mystatea.ru (without trailing slash).

Advisor is running, but data doesn't appear on the dashboard

Cause: the account isn't registered on mystatea.ru, or the account number in MT5 doesn't match the one used during registration.

Solution:

1. Register at mystatea.ru/register/ with your trading account number
2. Make sure you're logged into MT5 with the same account you registered with
3. Open the "Experts" tab in MT5 — the log will show the actual error from the server
