What is happening
The platform stops responding, lags badly, or closes on its own. Because this can strike while you have open trades, it is worth fixing the causes and having a backup route to your account.
Common causes
Too many charts, indicators, or EAs running at once, overloading your computer. A heavy or badly written custom indicator or EA. Not enough memory or a slow machine. A poor connection causing timeouts. Corrupted history or profile files. Or an outdated platform version.
Step-by-step fix
Reduce the load: close charts you do not need, remove unused indicators and EAs, and lower the number of bars in history. Restart the platform, and the computer if needed. Update to the latest platform build. If a specific indicator or EA triggers the freeze, remove it and test. If profiles are corrupted, reset to a clean template.
For serious, always-on trading, a VPS gives a stable, dedicated environment and keeps trades running even if your own device fails.
How to prevent it
Keep the workspace lean, run trustworthy indicators and EAs only, keep the platform updated, and use adequate hardware or a VPS. Always know how to reach your account by mobile or web if the desktop freezes.
Broker's fault or yours?
Freezes are usually local — hardware, connection, or overloaded software on your side — not the broker. The important thing is having a backup way to manage positions so a freeze never leaves you unable to act on a live trade.
