MetaTrader 5 keeps freezing? 3 quick fixes that work

MetaTrader 5

Quick summary: You're in the middle of a trade, and suddenly MetaTrader 5 freezes — charts stop updating, orders won't go through. This guide walks you through the most common reasons why MT5 freezes or lags and gives you step‑by‑step fixes you can apply right now. No tech degree required.

Metatrader 5_ full guide

Let’s be real: nothing’s worse than watching your screen freeze while a trade is moving. MetaTrader 5 is a powerful platform, but sometimes it acts up. The good news? Most freezes come from the same three or four issues. Once you know what to look for, you can fix them in minutes and get back to trading.

Why does MetaTrader 5 freeze? (the usual suspects)

Before we jump into the fixes, it helps to understand why this happens. MetaTrader 5 is heavier than its older brother MT4 — more features, more data, more demands on your computer and internet. Here’s what usually causes the freeze:

• Too many charts & indicators – every open chart eats memory.
• Internet hiccups – unstable connection makes the platform hang.
• Corrupted cache or history data – old files cause conflicts.
• Outdated version – running an old build of MT5.
• Computer resources – MT5 needs decent RAM and CPU.

Now let’s go through the fixes — from the simplest (30 seconds) to the more advanced (a few minutes).

Fix 1/ restart the right way

Yeah, I know — “turn it off and on again” sounds too simple. But with MT5, a full restart often clears temporary glitches. Not just closing the window, though. Here’s the better way:

1. Close MetaTrader 5 completely – make sure it’s not running in the system tray (check near the clock, right‑click and exit).
2. Open your Task Manager (Ctrl+Shift+Esc) and look for any remaining terminal.exe processes. End them.
3. Wait 10 seconds, then restart MT5.

Important: This clears the memory cache and gives the platform a fresh start. Do this before trying anything more complicated.

Fix 2/ reduce the load (charts & indicators)

Every chart you open, every indicator you add, takes a slice of your computer’s power. If you’re the kind of trader who opens 15 pairs with three indicators each, MT5 might choke. Try this:

• Close charts you’re not actively watching.
• Remove unused indicators — right‑click on the chart > “Indicators list” > delete the ones you don’t need.
• If you use custom Expert Advisors (EAs), turn off those you aren’t trading right now.

Pro tip: You can save your workspace first (File > Save workspace) so you can restore it later if needed. After reducing the load, check if the freezing stops.

Do you need the full history?

Setting	Effect on performance	Best for
Max bars in history: unlimited	High memory usage, slower loading	Long‑term backtesting only
Max bars: 50,000 – 100,000	Balanced – enough for most traders	Daily chart traders
Max bars: 10,000 – 20,000	Lightweight, smooth scrolling	Intraday trading, slow computers

How to adjust: Tools > Settings > Charts tab – change “Max bars in history” and “Max bars in window”.

Fix 3/ clear the cache and old data

MetaTrader 5 stores a lot of historical data on your hard drive. Over time, that data can get corrupted or bloated, causing freezes. Here’s how to clean it up:

1. In MT5, go to File > Open Data Folder. This opens the folder where all your settings, indicators, and history are stored.
2. Close MT5 completely (use Task Manager to be sure).
3. Inside the data folder, open the ‘bases’ folder and delete everything inside (don’t worry, it will rebuild).
4. Also open the ‘history’ folder, then the folder with your broker’s name — delete all files there.
5. Restart MT5. It will download fresh history data from your broker.

✳️ Note: This process removes old chart templates? No, templates are stored in ‘Profiles’ and ‘MQL5’ folders — leave those alone unless you want to reset everything.

Internet and connection: the hidden freeze cause

Sometimes MT5 isn’t really frozen — it’s just waiting for data because your internet dropped for a second. But the interface becomes unresponsive. Try these connection‑related fixes.

Check your ping and server

• Look at the bottom right corner of MT5: if it says “no connection” or circles are gray, you’re disconnected.
• Right‑click on the connection icon > “Servers” – try switching to a different server offered by your broker (sometimes the auto one is overloaded).
• If you use WiFi, try plugging in an ethernet cable for a more stable connection.

Use a VPS for 24/7 stability

If you run Expert Advisors or trade while you’re away, a Virtual Private Server (VPS) can save you. It’s a remote computer that runs MT5 with a super‑stable internet connection. Many brokers offer free VPS if you have a certain account balance. No more freezing because your laptop went to sleep.

Advanced tweaks (still beginner‑friendly)

If the quick fixes didn’t help, these next steps dig a little deeper — but they’re still things you can do without being a programmer.

Update MetaTrader 5

Running an old build can cause bugs and freezes. To update: Help > Check for updates. If a new version is available, install it. Some brokers have their own custom MT5 build — in that case, download the latest version from your broker’s website.

Disable unnecessary EAs and scripts

Go to View > Navigator. Look at the “Expert Advisors” section. If there are lots of EAs with a little “x” on them, they’re not running — that’s fine. But if any EA is actively running on a chart (smiley face icon) and you’re not using it, remove it from the chart. Same for scripts.

Quick symptom checker

Symptom	Likely cause	Try this fix first
Charts freeze but mouse moves	Data overload or connection	Reduce charts / restart
Entire program not responding	Memory leak / corrupted cache	Clear history folder
Freezes when placing an order	Server communication issue	Check internet / switch server

“I used to restart my computer five times a day because of MT5 freezes. Turned out I just needed to clear the cache — now it runs smooth for weeks.”

How to stop freezes before they start

Fixing a freeze is great, but keeping MetaTrader 5 stable is even better. Here’s a simple weekly maintenance routine:

• Restart MT5 at least once a day – especially if you leave it running 24/7.
• Don’t go crazy with indicators – use only what you really need.
• Keep your data folder clean – every two weeks, delete the ‘history’ cache as shown above.
• Update when your broker recommends it – sometimes they fix memory leaks.

⚠️ Important: not every freeze is your fault

Sometimes the problem is on your broker’s side — their servers might be down or under maintenance. If you’ve tried everything and MT5 still freezes, contact your broker’s support. Also check if other traders using the same broker report issues.

the bottom line

MetaTrader 5 is rock‑solid once you understand its limits. Most freezes are caused by too much data, outdated files, or small internet glitches — all things you can fix in a few minutes. Start with a simple restart, then clear the cache, and finally reduce the chart load. That should solve 90% of cases.
