Troubleshoot MT4/MT5 freezing issues

There are several possible reasons why MT5 may freeze. Work through the suggested solutions step by step to address the problem.

If many indicators or Expert Advisors (EAs) are applied to your charts, MetaTrader 5 (MT5) may become slow or freeze. In such cases, removing unused EAs and indicators can help resolve the issue.

It's also important to note that some EAs and indicators can be resource-intensive depending on their settings. For example, while many indicators allow you to customize the period, setting a very long period can significantly increase the calculation load and cause delays. Additionally, if available, the "Max bars" setting discussed below can have a major impact on performance.

Depending on your settings, MT5 may continuously load historical data, including data that is not visible on the chart. Since excessive data loading may slow down MT5 or cause it to freeze, it's recommended to limit the amount of data to only what is necessary.

You can adjust this in the "Max bars in history" option on MT5. For detailed instructions, refer to steps 1 and 2 in the article "Import historical data".

If you don't need news updates in MT5, disabling the feature can help improve performance. To do this, go to the menu bar and click "Tools" > "Options" (Shortcut keys: Ctrl+O).

The Market Watch window constantly consumes network and CPU resources to retrieve quotes and daily price changes for every listed symbol. Hiding unused ones can help optimize performance. For detailed instructions, refer to steps 3 in the article "Manage symbols in Market Watch".

Using an outdated version of MT5 can lead to slowdowns and lag, especially if it doesn't support the latest OS or lacks performance optimizations. It can also increase security risks. Make sure to keep your MT5 platform up to date.

With the growing use of WQHD and 4K monitors, more users are running MT5 at high resolutions. However, high-resolution displays can slow down MT5's performance and may even cause the platform to freeze. On MT5, you can try lowering your screen resolution to improve responsiveness.

When running multiple programs alongside MT5, it can lag or freeze. Stopping unnecessary programs may enhance responsiveness.

If your device's specifications are too low, it may cause MT5 to freeze. Check the Task Manager, Resource Manager, or MT5's Task Manager to see if MT5 is using excessive CPU or RAM. If that's the case, consider buying a more powerful device.
