MT4 Not Working? Start Here to Fix It

If MT4 is not working, the fix is usually quick — and almost always points to one of a handful of causes. Most MetaTrader 4 problems fall into five buckets: it won't open or install, charts are frozen, there are no prices ('no connection'), you can't log in, or you can't place a trade. Find your symptom below, try the quick fix, then follow the link to the full guide.

First, the 30-second check

Before anything else, rule out the simplest causes. Many "MT4 is broken" moments are just a dropped connection or a platform that needs a restart.

  • Check your internet works (open any website).
  • Look at the bottom-right of MT4 — if it doesn't show live data rates, MT4 isn't connected to your broker.
  • Fully close MT4 and reopen it; this clears most temporary glitches.
  • Make sure it isn't the weekend — the forex market is closed from Friday evening to Sunday evening.

MT4 won't open, or charts are frozen

  • Won't open / install: right-click the shortcut ▸ Run as administrator; if it still won't launch, uninstall and reinstall a fresh copy from your broker, and allow MetaTrader 4 through your firewall/antivirus.
  • On a Mac? A Windows .exe won't open natively — see MT4 for Mac.
  • Charts frozen / prices not moving: this is almost always a lost data feed, not a crash. Check the connection (bottom-right); a single stuck chart can be refreshed with right-click ▸ Refresh. Full fix → MT4 no connection.

No prices, or you can't log in

  • "No connection" / no prices: confirm your internet, then re-check you logged in to the exact server your broker gave you. Full guide → MT4 no connection.
  • Login fails / "invalid account": the server is usually the culprit, and you must use your master (not investor) password. Full guide → MT4 login.

You can't place a trade

If the order window won't let you trade, MT4 is usually telling you why — read the message:

  • "Trade context is busy" — MT4 is still finishing a previous order; wait and retry → trade context is busy.
  • "Off quotes" — the price moved or your broker can't fill it → off quotes (error 136).
  • "Market closed" — the instrument is outside its trading hours → market closed.
  • Trade buttons greyed out: you may be on an investor (read-only) login, or AutoTrading is off for an EA — check your login type.
Still not working?

If you've tried the matching fix and MT4 still misbehaves, the problem may sit with your broker — server downtime, maintenance, or unreliable execution. Frequent disconnects or constant "off quotes" are often broker-side, not your fault.

Persistent disconnects or requotes?

A stable, well-regulated broker prevents a lot of these headaches. XM is a long-established, multi-regulated broker with reliable platforms across desktop, mobile, and WebTrader.

Frequently asked questions

Why is my MT4 not connecting to the internet?

Usually one of three things: your internet dropped, a firewall or antivirus is blocking MT4, or you logged in to the wrong server. Check the connection indicator at the bottom-right of the platform, then confirm your broker's server name at login. Our MT4 no connection guide walks through each fix.

Why won't MetaTrader 4 open on my computer?

The most common causes are permissions, a corrupted install, or security software blocking it. Try right-clicking the shortcut and choosing 'Run as administrator'. If it still won't launch, uninstall and reinstall a fresh copy of MT4 from your broker.

Why can't I place a trade in MT4?

MT4 usually tells you why in the order window or Journal. 'Trade context is busy' means wait and retry; 'Off quotes' means the price moved; 'Market closed' means the instrument is outside its hours. Greyed-out trade buttons can mean you're on a read-only investor login.

Is MT4 still supported in 2026?

Yes. MetaTrader 4 is still actively maintained (the latest build is 1460, March 2026) and widely offered by brokers, even though MetaQuotes no longer sells new MT4 licences. You download it through a broker rather than from MetaQuotes directly.

My charts froze but the platform didn't crash — what's wrong?

A frozen chart almost always means MT4 lost its live price feed, not that the software broke. Check the connection status at the bottom-right. If it shows no connection, reconnect; if it's a weekend or after-hours, that market is simply closed.
