Introduction

MetaTrader 4 (MT4) is a popular platform for forex traders due to its user-friendly interface, robust charting capabilities, and advanced analysis tools. However, many traders experience issues with MT4 crashing, freezing, or hanging, which can lead to missed trades and lost profits. In this post, we’ll explore some tips and strategies to help prevent these issues from occurring and keep your MT4 terminal running smoothly.

Tips and Strategies for Preventing MT4 Issues

Use a Reliable Internet Connection

A reliable internet connection is essential for the smooth operation of MT4. Here are some tips to ensure a stable internet connection:

• Use an Ethernet cable instead of Wi-Fi: A wired connection is more stable and faster than a wireless one.
• Avoid peak usage hours: During peak usage hours, internet speeds can slow down significantly. Try to trade during off-peak hours to avoid these issues.
• Upgrade your internet plan: If you have a slow internet connection, consider upgrading to a faster plan.

Optimize Your MT4 Settings

Customizing the MT4 settings can help improve performance and prevent crashes or freezes. Here are some tips for optimizing your settings:

• Reduce the “Max bars in chart” setting: it caps how many bars each chart loads when it opens, and those bars, with every indicator calculated on them, cost processor time and memory. Go to “Tools” > “Options” > “Charts” and lower “Max bars in chart”. The “Max bars in history” value beside it only caps how many bars are saved to disk when a chart closes.
• Turn off features you do not use: if you do not read the news feed inside the terminal, go to “Tools” > “Options” > “Server” and uncheck “Enable news”. (“Visual mode” is not a terminal setting: it is a checkbox of the Strategy Tester.)

Keep Your MT4 Terminal Updated

Make sure your terminal runs a current build. Updates often include bug fixes and performance improvements. The MT4 “Help” menu has no “Check for updates” command: to see which build you run, open “Help” > “About”, and if it is old, download the current installer from your broker.

Monitor Your PC’s Resources

A lack of PC resources can cause crashes or freezes. Here are some tips for monitoring your PC’s resources:

• Use the Task Manager (Windows) or Activity Monitor (Mac) to monitor CPU, memory, and disk usage.
• If your PC is running low on resources, close any unnecessary programs or processes.

Avoid Running Too Many Expert Advisors (EAs) Simultaneously

Running too many EAs can cause instability in the MT4 platform. Here are some tips for managing EAs:

• Stop EAs you do not need: remove each one from its chart through the chart’s right-click menu, under “Expert Advisors”, or close the chart it runs on. Deleting an EA in the “Navigator” window does not stop a copy that is already running on a chart.
• Use a VPS: A virtual private server can provide a stable environment for running EAs. A VPS allows you to run your trading platform on a remote server, which can help reduce the strain on your PC’s resources.

Use a VPS

A VPS can provide a stable and reliable environment for running MT4. Here are some tips for using a VPS:

• Choose a VPS provider that specializes in MT4 hosting.
• Use a VPS that is located near your broker’s server to reduce latency.
• Configure your VPS to run MT4 automatically when it starts up.

Close Unnecessary Programs

Having too many programs open can strain PC resources and cause issues with MT4. Here are some tips for closing unnecessary programs:

• Close any unnecessary programs or applications running on your PC while using MT4.
• Manage background processes using the Task Manager (Windows) or Activity Monitor (Mac).

Limit the Bars Your Charts Load

MT4 has no command that clears a cache. What builds up is price history, and two settings control how much of it the terminal handles:

• In “Tools” > “Options” > “Charts”, “Max bars in chart” caps the bars a chart loads when it opens, and “Max bars in history” caps the bars saved to disk when it closes. Lower values leave the terminal less to load and store.
• The “Max bars in chart” limit applies when a chart opens, so after lowering it, close and reopen your charts or restart MT4.
