A lot of beginners don't know how to insert the EA, indicator, and other files in Metatrader 4 and Metatrader 5, so today I will show you how to do it. It's the same way for both terminals. It will be enough to do it once, and you will know it forever.
1. First, open your terminal.
2. Then go to > File > Open Data Folder.
3. Then go to >MQL4/5.
4. Choose what file you want to insert. If it's an Expert Advisor, then insert it in the "Experts" folder. If it's an indicator, then insert it in the "Indicators" folder.
5. I opened the "Experts" folder as an example. Copy your desired EA and paste it in this folder.
6. Then go to the terminal, move your mouse over Expert Advisors, and press Refresh; after that, you will see your EA instantly. Finally, you're ready to apply it to the chart.
