※記事内に広告を含む場合があります。

To trade FX, you need to use the MT4 platform. However, while using MT4, you might encounter an “Invalid Account” error, which can prevent you from continuing your trades. This blog post thoroughly explains the causes and solutions for this error. It’s packed with tips for smooth MT4 usage, so please read on.

1. Common Causes of the “Invalid Account” Error in MT4

When using MT4, you might encounter an “Invalid Account” error message. This error can occur for various reasons, so it’s crucial to understand its causes. Below, we’ll explain the main reasons in detail.

1. Account Status Check

One of the most common reasons is that your account has become invalid. This can happen if the account hasn’t been used for a long period or if it has been temporarily restricted. Check your account’s usage status and reactivate it if necessary.

2. Login Information Verification

Mismatching login credentials are also a frequent cause of the “Invalid Account” error. It’s especially common to make mistakes when entering your **account number or password**, so it’s important to double-check that you’ve entered them accurately. Pay particular attention to avoiding full-width characters or unnecessary spaces.

3. Importance of Server Selection

In MT4, selecting the correct server is crucial. If you mistakenly choose a different server, an error will occur because you won’t be able to connect to your account. Remember to also verify that the server you’ve selected is correct.

4. Software Version Check

Using an outdated version of MT4 can also cause login errors. Older versions may not be compatible with new servers or features, so we recommend updating to the latest version.

5. Server Status

If your forex broker’s server is undergoing maintenance or experiencing an outage, an “Invalid Account” message may appear. In this case, it’s a good idea to wait a while and then try logging in again.

6. Check for Notifications from Your Broker

It’s especially important to check for communications from your forex broker if the server name has changed. Regularly check your inbox to avoid missing important announcements.

Understanding these factors will help you deal with the “Invalid Account” error. Identifying the root cause of the problem and contacting customer support if needed can also be effective.

2. Verify Your Account Number Is Entered Correctly

 

One of the reasons the “Invalid Account” error message appears in MT4 is an **incorrect account number entry**. Even with accurate login information, an improperly entered account number can cause connection issues. Therefore, it’s important to carefully re-verify your account number and pay special attention to the following points:

Common Input Errors

Common mistakes that occur when entering an account number primarily include:

  • Full-width vs. Half-width Characters: If you’re using your keyboard in Japanese input mode, characters might be entered in full-width, which can prevent the account number from being correctly recognized.
  • Carelessness During Copy & Paste: Unnecessary spaces or line breaks can be included when copying. While it’s recommended to manually enter the number if possible, always double-check the content if you paste it.

Account Number Verification Steps

Here are specific steps to confirm that your account number is accurate:

  1. Re-check Account Opening Confirmation Email
    – The confirmation email you received after opening your account usually contains the necessary login information. Review this email.
  2. Utilize Online Client Portal
    – You can log in to the client portal provided by each forex broker to check your account information. Make sure to confirm your account number on the account list page.
  3. Check Monthly Statements and Other Documents
    – Some brokers send monthly statements that include your account number. Refer to these to ensure your account number is accurate.

Re-entering Your Account Number

Once you’ve confirmed your account number, go back to MT4 and try re-entering it. Key points to be aware of at this stage include:

  • When entering, remove any unnecessary text to avoid mixing it with other information.
  • Writing down the confirmed account number in a notepad or notebook can help alleviate any uncertainty.

Entering the correct account number should resolve the “Invalid Account” error. If the problem persists, consider contacting customer support.

3. Confirm You Haven’t Selected the Wrong Server Name

 

When accessing MT4, the selection of the server name is extremely important. **Choosing an inappropriate server name can lead to an “Invalid Account” error.** Here, we will explain how to verify the correct server name and key points for selection.

How to Check the Server Name

  1. Check Your Account Registration Information
    – Documents sent during account opening should contain the required server name. It’s crucial to check the email you received during registration or your personal client portal.
  2. Review the Server List
    – You can also use the “Scan for servers” feature on the MT4 login screen. This feature displays a list of available servers, helping you choose the correct one. The specific steps are as follows:
    • Launch MT4 and click on the “File” menu on the login screen.
    • Select “Open an account” (or “Open a Demo account”) and perform a “Scan.”
    • From the displayed servers, select the one corresponding to your account.

Impact of Incorrect Server Selection

If you choose the wrong server name, “Invalid Account” may be displayed even if you enter the correct login information. **This is particularly important for those with multiple accounts or if there has been a server name change from your forex broker.**

Regarding Server Name Change Notifications

Forex brokers occasionally change server names. In such cases, **notifications are usually sent via email or other communications from the broker.** Therefore, it’s recommended to regularly check for the latest information. Keep your account opening correspondence safe to avoid missing important announcements.

Significance of Selecting the Correct Server Name

Choosing the correct server name is essential for smooth MT4 usage. **Selecting the wrong server can lead to unexpected errors and problems, so it’s important to verify carefully during selection.** Once the appropriate login information and procedures are confirmed, you can trade with confidence.

4. Verify Your Password Is Entered Correctly

 

If an “Invalid Account” error appears in MT4, incorrect password entry is often the cause. This section will outline several points to check to ensure you’re entering your password correctly.

Password Character Restrictions

First, be aware that passwords often have the following restrictions:

  • Case Sensitivity: Passwords are case-sensitive. If you don’t consider this when typing, it will be recognized as an incorrect password.
  • Use of Symbols and Numbers: Many forex brokers require passwords to include symbols and numbers. Verify that these are entered accurately.

Auto-fill Feature Check

On smartphones and PC browsers, you can use the auto-fill feature to enter passwords. However, if this feature has stored an incorrect password, you might inadvertently enter the wrong one. Follow these steps to check:

  1. Manual Entry: Disable the auto-fill feature and try entering your password manually. Be careful not to include any unintended spaces during this process.
  2. Review Stored Passwords: It’s recommended to check the content of auto-saved passwords in your browser or app settings and update them to the correct ones.

How to Verify the Correct Password

If you don’t know your password or need to reset it, you can follow these steps to set a new one:

  • Access Client Portal: Log in to the “My Account” or “Client Portal” section on your forex broker’s official website and look for links like “Change Password” or “Forgot Password.”
  • Execute Reset Procedure: Follow the instructions, enter your email address, and receive a reset email to set a new password.

Finding Errors During Input

When entering your password, paying attention to the following points can help you spot errors more easily:

  • Verify While Typing: By comparing what you’re typing with what’s displayed on the screen, you can notice input errors.
  • Caps Lock Status: Check if your keyboard’s “Caps Lock” key is on, as this can cause unexpected case changes.

By keeping the above points in mind and checking beforehand, you can increase the likelihood of avoiding the “Invalid Account” error in MT4. Before attempting to log in again, remember to verify your password.
