Installing an EA (Expert Advisor) in MT5

From the code download to the running EA on your chart — all on one page.

You've bought an Expert Advisor from us and now want to get it running in MetaTrader 5. Here is the complete workflow — from downloading the file to the activated EA that opens trades.

1 — Download the file

1

Log in to your Library

Go to tmb-invest.de/library/ and log in. Under "My purchases" you'll find all the products you have bought so far.

2

Download the EA file

Click the product and then "Download". You get a ZIP file or directly an .ex5file (compiled) or .mq5 (source code). Save the file somewhere you can find it again — e.g. in your Downloads folder.

2 — Place the file in MT5

1

Open MT5 & find the data folder

Open MetaTrader 5. In the top menu: File → Open Data Folder. A Windows Explorer window opens with the MT5 data directory.

2

Navigate to the Experts folder

In the data folder: MQL5 → Experts. This is the right place for EAs.

3

Paste the EA file

Copy the .ex5 or .mq5file from your Downloads folder into MQL5/Experts/. If the file is in a ZIP, unpack it first.

3 — Compile the code (only for .mq5)

If you only have a compiled .ex5 you can skip this step. If you received the source code .mq5 it has to be compiled once:

1

Open MetaEditor

In MT5: Tools → MetaQuotes Language Editor (or the F4 key).

2

Open & compile the file

In MetaEditor: File → Open → choose the .mq5file. Then click "Compile" (F7) in the top menu.

3

Verify success

You'll see the result at the bottom of MetaEditor. "0 errors, 0 warnings" means everything is fine. A .ex5file was generated automatically and is in the same folder.

4 — Apply to chart

1

Open the Navigator window

In MT5 open the Navigator: View → Navigator (or Ctrl+N). In the Navigator expand "Expert Advisors" — your EA should now be visible there. If not: right-click → "Refresh".

2

Enable algo trading

In the top MT5 menu: make sure the "Algo Trading" button is enabled (green). Without this setting the EA executes no trades.

3

Drag the EA onto the chart

Open a chart for the desired symbol (e.g. EURUSD, M15). Drag and drop the EA from the Navigator onto the chart.

4

Check settings

A settings window opens. In the "Common" tab: tick "Allow algorithmic trading". In the "Inputs" tab: adjust the parameters to your strategy. Confirm with OK.

5

Activate licence

On first start the EA asks for your licence key. You'll find it in the confirmation email or under /library/ in your account. Paste it in → the EA activates and is ready to use.

6

Smiley check

If everything works, you see a green smiley 😊 in the top right of the chart. Red smiley or crying face = something is wrong (algo trading off, licence problem, EA logic blocked). See our troubleshooting articles.

Done! Your EA is now running on the chart. It trades according to the configured rules as soon as the conditions are met. Leave the chart and MT5 open — the EA only works while MT5 is running.
Important: Test every EA on a demo account first before risking real money. Even our tested EAs can perform differently on your broker / your settings than with us.
