Frequently Asked Questions

How do I install an Expert Advisor on MetaTrader 5?

In MetaTrader 5, open File > Open Data Folder, then go into MQL5 > Experts and copy your EA's .ex5 (or .mq5) file there. Restart MT5 or right-click Navigator > Refresh, drag the EA from the Navigator's Expert Advisors list onto a chart, tick 'Allow Algo Trading' in the dialog, and enable the global Algo Trading button in the toolbar. A smiley face in the chart's top-right corner means the EA is running.

Where do I put the EA file in MT5?

The correct folder is the MQL5\Experts subfolder inside the MT5 data folder, which you reach via File > Open Data Folder (not the Program Files install directory). Compiled EAs use the .ex5 extension; source files use .mq5 and must be compiled in MetaEditor first. After copying the file, refresh the Navigator so the EA appears under Expert Advisors.

Why isn't my EA trading after I installed it?

The most common causes are: Algo Trading is disabled (the toolbar button must be green and the chart smiley must be happy, not a sad face or an X); 'Allow Algo Trading' was unticked when you attached the EA; the market is closed or it is outside the EA's trading window; the symbol or timeframe does not match the EA's settings; or the account has insufficient margin. Check the Experts and Journal tabs for error messages that explain exactly what the EA is waiting for.

How do I enable AutoTrading (Algo Trading) in MT5?

Click the 'Algo Trading' button in the MT5 toolbar so it turns green, and make sure 'Allow Algo Trading' is ticked in the EA's input dialog when you attach it. You can also check Tools > Options > Expert Advisors. When both the global button and the per-EA permission are on, the chart shows a smiling face; a frown or a 'no entry' icon means automated trading is blocked.

Can I install an MT4 Expert Advisor on MT5?

No. MT4 EAs are written in MQL4 and compiled to .ex4, while MT5 uses MQL5 and .ex5 — the two are not interchangeable. You need the MT5 version of the EA from the vendor. If only an MT4 build exists, run it on MetaTrader 4 instead; most reputable vendors ship separate MT4 and MT5 versions.

Do I need a VPS to run an EA on MT5?

Not to install it, but you usually want one to run it seriously. An EA only trades while MT5 is open and connected, so a VPS keeps it running 24/5 without leaving your home PC on, and a VPS near your broker's server reduces the slippage that matters for scalping and high-frequency strategies. For casual or demo testing a desktop is fine; for live trading a $10-$30/month VPS is the norm.
