How to Copy Between Two Accounts from the Same Broker

If your transmitter and receiver accounts are both held with the same broker, you must install a separate, second terminal of that broker onto your Windows computer or VPS. This is necessary to allow both accounts to run simultaneously in separate terminal instances.

To achieve this:

1. Download the MT4/5 terminal installer directly from your broker's website.

2. During the installation process, choose a different destination folder (e.g., Program Files/Broker Name MT4 - 2) within your Program Files directory for the second terminal .

Resolving Multiple Receiver Copies

If you observe multiple identical trades being opened on the receiver account(s) following a single trade on the transmitter, the issue is likely due to running more than one instance of the Local Trade Copier EA MT4/5© on either the transmitter or receiver terminals.

Crucial Rule:

• Transmitter: Only one instance of the Local Trade Copier EA MT4/5© should be attached to a single chart of any symbol.

• Receiver: Similarly, only one instance should be attached to a single chart of any symbol.

Attaching a single instance per account is sufficient to copy all trades from all symbols.

Please review the quick setup video for the correct procedure, paying close attention after 1:30 for suffix settings and the third part for handling special symbols.

* Normally use one EA instance per account. Exception: an account intentionally operating simultaneously as both Receiver and Transmitter requires separate instances for each role. 

Copied Trades Closing Instantly on Receiver Account

If copied trades are immediately closing on the receiver account, it usually indicates a conflict caused by multiple instances or external EAs.

Please verify the following:

• Ensure that only one instance of the Local Trade Copier EA MT4/5© is attached to a single chart on both the transmitter and receiver terminals.

• Verify that no other copier or multiplier EA is running on any chart within the receiver terminal. The Local Trade Copier EA MT4/5© must be the only trade management EA operating on the receiver account.

For further details on the error, check the Experts tab logs within the receiver terminal.

Addressing the VPS MathRound Issue

A known issue affecting some VPS configurations causes lot size calculations to incorrectly default to 0.01 due to a bug in the terminal's MathRound function. This problem is typically tied to the underlying physical CPU used by the VPS.

Recommended Solution:

• Before changing VPS providers entirely, contact your current provider and request to be moved to a different server or virtual CPU within their system. Switching processors has successfully resolved this issue for many users.

• To confirm that the VPS is the source of the problem, it is recommended to test the Local Trade Copier EA MT4/5© on a local machine or a different, known-good VPS.

• It is best practice to avoid VPS environments where the MathRound function does not operate correctly.

Simple 1 Transmitter to 1 Receiver Setup (No Suffixes)

This video demonstrates a straightforward configuration where a single transmitter account copies trades to a single receiver account, and neither account utilizes symbol suffixes.

What is a Suffix? A suffix is a letter or group of letters added at the end of a trading symbol to denote account type or server (e.g., the .r in EURUSD.r). If your symbols are simply EURUSD or XAUUSD, you have no suffix.

Copy from 1 Transmitter to 1 Receiver - Transmitter with .r Suffix

This video demonstrates a simple 1 Transmitter to 1 Receiver setup where the transmitter account's symbols include a suffix (e.g., the .r in EURUSD.r).

A suffix is a group of letters added at the end of a symbol. In this setup, the suffix is automatically mapped to the receiver account without requiring additional settings in the EA's inputs.

Important: This automatic mapping feature works only for suffixes that include a dot (e.g., EURUSD.r). It does not work for suffixes without a dot (e.g., EURUSDecn or EURUSD+).

Copy from 1 Transmitter to 1 Receiver - Non-Dot Suffix

This video demonstrates a simple 1 Transmitter to 1 Receiver setup where the transmitter account's symbols use a non-dot suffix (e.g., the + in EURUSD+).

A suffix is a letter or group of letters added at the end of a symbol.

Manual Input Required: Because the suffix does not contain a dot (like the + example), you must manually enter the transmitter's symbol suffix (e.g., +) into the Suffix of the Transmitter Account setting found in the receiver account's configuration.

Copy from 1 Transmitter to 1 Receiver - Receiver Account with Suffix

This video demonstrates a simple 1 Transmitter to 1 Receiver setup where the receiver account's symbols include a suffix (e.g., the .r in EURUSD.r).

A suffix is a letter or group of letters added to the end of a symbol.

Manual Input Required: In this scenario, you must manually enter the receiver's symbol suffix (e.g., .r) into the Suffix of the Receiver Account setting found within the receiver account's configuration.

Copy from 1 Transmitter to 1 Receiver - Same Symbol Suffix Mapped Automatically

This video showcases a 1 Transmitter to 1 Receiver setup where both the transmitter and receiver accounts use the exact same symbol and suffix (e.g., EURUSD.r). When the symbols are identical, the suffix is often mapped automatically, allowing trades to be copied seamlessly without manual configuration.

Troubleshooting Automatic Mapping: If the automatic mapping of the dot suffix fails between the terminals, you will need to manually configure the suffix in the receiver account's settings:

Suffix of the Transmitter Account: m (or whatever your specific suffix is)

Suffix of the Receiver Account: m (or whatever your specific suffix is)

Reminder: A suffix is a group of letters added to the end of a symbol, like .r in EURUSD.r.

Copy from 1 Transmitter to 1 Receiver - Different Symbol Suffixes

This video demonstrates a configuration where the transmitter and receiver accounts use different suffixes in their symbols (e.g., the transmitter uses a + suffix, while the receiver uses a .r suffix). When the suffixes differ, you must manually enter both suffixes into the receiver account's settings:

Suffix of the Transmitter Account: +

Suffix of the Receiver Account: .r

A suffix refers to a letter or group of letters added to the end of a symbol (e.g., the .r in EURUSD.r).

Important Note on Automatic Mapping: Remember that automatic suffix mapping only works for transmitter suffixes that include a dot (e.g., EURUSD.r). It does not work for non-dot suffixes (e.g., EURUSDecn or EURUSD+).

Copy from 1 Transmitter Account to 2 Receiver Accounts (Transmitter with Suffix)

This video demonstrates a setup involving one transmitter account and two receiver accounts. The transmitter account uses a dot suffix (e.g., .r) at the end of its symbols. Because the suffix includes a dot (e.g., .r in EURUSD.r), it is automatically mapped onto both receiver accounts, requiring no additional configuration for the suffix in the receiver EA inputs.

A suffix is a character or group of characters added to the end of a symbol.

Important Note: This automatic mapping feature is only effective for transmitter suffixes that have a dot following the main symbol (e.g., EURUSD.r). It does not apply to other formats like EURUSDecn or EURUSD+.

Copy from 1 Transmitter Account to 2 Receiver Accounts (One Receiver with Suffix)

This video demonstrates a setup involving one transmitter and two receiver accounts, where one of the receiver accounts has a suffix in its symbols. For the receiver account that uses the suffix, you must manually enter that suffix (e.g., .r) into the Suffix of the Receiver Account setting within that account's configuration. The other receiver account (without a suffix) does not need this setting adjusted.

A suffix is a letter or group of letters added to the end of a symbol, such as the .r in EURUSD.r.

Copying from 2 Transmitter Accounts to 1 Receiver Account (One Transmitter with Suffix)

This video demonstrates a setup involving two transmitter accounts and one receiver account. One of the transmitter accounts uses a dot suffix (e.g., .r) at the end of its symbols, while the other does not. The .r suffix on the transmitter account is automatically mapped onto the receiver account, meaning no special configuration for that specific suffix is needed in the receiver's EA inputs.

A suffix is a letter or group of letters added to the end of a symbol (e.g., the .r in EURUSD.r).

Important Note: Automatic transmitter suffix mapping only applies to suffixes that include a dot (e.g., EURUSD.r). It does not apply to suffixes in other formats, such as EURUSDecn or EURUSD+.

Copying from 2 Transmitter Accounts to 1 Receiver Account (Receiver with Suffix)

This video demonstrates a setup involving two transmitter accounts and one receiver account where the receiver account's symbols include a suffix. In this configuration, the suffix of the receiver account symbols (e.g., .r) must be manually specified in the Suffix of the Receiver Account setting within the receiver's configuration.

A suffix is a letter or group of letters added at the end of a symbol, such as .r in EURUSD.r.

Copying from 2 Transmitter Accounts to 2 Receiver Accounts

This video demonstrates a straightforward setup for configuring the trade flow between two transmitter accounts and two receiver accounts.

No Copying Between Transmitter and Receiver Accounts - Receiver Account in Investor Mode

This video demonstrates an issue where trade copying fails because the receiver account is logged in using the Investor Password. When a user logs in with the Investor Password, they are granted monitoring access only, which means the account has no full trading privileges and cannot open or close trades. Consequently, the trade copier cannot function.

The Solution

1. Switch Passwords: Log out of the receiver terminal and log back in using the Master Password (which grants full trading privileges).

2. Re-enable Trading: After the password change, the Auto/Algo Trading button on the terminal toolbar is usually disabled for security. Re-enable this button.

Once these steps are completed, the copying should resume without issues.

No Copying - When the Transmitter Broker is a Scam!

I have received contacts from several users attempting to copy trades from "miracle" trading accounts that always show guaranteed profits on symbols like XAUUSD. These accounts often originate from suspicious brokers, including (but not limited to) LegoMarket, MaxGlobal, Zentrade, GlobalPremier, HanjuGlobal, or AlfaSuccessCorp. The trades appearing on these transmitter accounts were never genuinely opened—they were fabricated in the trading history, often with cooperation between the scammer and the broker. This scheme is designed to lure unsuspecting traders into opening accounts with these specific brokers, only for the traders to eventually lose their funds.

Important: Note that MQL5.com has banned these types of brokers, and they cannot publish signals in the Signals section. If trades from such an account cannot be copied, the issue is not with your Local Trade Copier EA MT4/5©, but a result of the underlying scam. Always be cautious of brokers and traders promising unrealistic results.

Copying Between 3 Accounts: Dual Role (Receiver & Transmitter)

This video demonstrates a complex, three-account setup where the second account serves a dual purpose:

1. Account 1 transmits trades to Account 2.

2. Account 2 acts as both a receiver (from Account 1) and a transmitter (to Account 3).

3. Account 2 must have two separate instances of the Local Trade Copier EA MT4/5© attached to two different charts to manage this dual functionality (one instance to receive, one instance to transmit).

Copying Special Symbols and Indexes with Different Suffixes and Symbol Names

This video demonstrates a setup where a single Transmitter Account copies special symbols and US stock market indexes (e.g., US500, US30) to two different Receiver Accounts. The first receiver account uses the same base symbols but includes a suffix (e.g., .r in US500.r). To ensure proper copying the suffix (e.g., .r) must be manually entered in the 'Suffix of the Receiver Account' setting.

The second receiver account uses entirely different names for the same symbols (e.g., SPX500 for US500 and WS30 for US30). To ensure proper copying these alternative symbols must be added to the 'Special Symbols' section of the second receiver account's configuration to map them correctly.

Copying Stocks Across Brokers Using Special Symbols Setup

This video demonstrates how to leverage the 'Special Symbols' configuration within the Local Trade Copier EA MT5 to successfully copy stock trades between different brokers, who often use unique ticker formats.

Example 1: Automatic Mapping (Dot Suffix)

• Transmitter Symbol: TSLA.NAS (Tesla stock with an exchange suffix).

• Receiver Symbol: TSLA (Tesla stock without a suffix).

• Result: Due to the dot suffix (.NAS), the trade copier automatically maps the symbol, and the copy executes seamlessly without requiring extra configuration.

Example 2: Manual Mapping (Special Symbols)

• Transmitter Symbol: ABBV.NYSE (AbbVie stock with an exchange suffix).

• Receiver Symbol: ABBVIE (The receiver broker uses the full name as the symbol).

• Configuration: The Special Symbols setting on the receiver's Local Trade Copier EA MT5 must be used to manually map the incoming transmitter symbol (ABBV.NYSE) to the receiver's symbol (ABBVIE) for correct execution.

Magic Numbers to Exclude from Copying

This video demonstrates how to use the 'Magic Numbers Not to Copy' setting to exclude specific trades from being copied from the transmitter to the receiver account. This is useful when trades originate from a source (like an EA or a different strategy) that you do not wish to replicate.

How to Identify and Exclude

1. In the transmitter account, hover your mouse cursor over the ticket number in the Trade or Trading History tab. The pop-up information will display the Expert ID, which is the trade's Magic Number.

2. In the video, a trade from an expert (e.g., "Manual Trade Panel EA MT4") is first copied normally.

3. The Magic Number of that expert is then added to the 'Magic Numbers Not to Copy' setting in the Local Trade Copier configuration.

4. Subsequent trades originating from that specific expert or source will not be copied to the receiver account.

Excluding Symbols from Copying

This video demonstrates how to use the 'Symbols Not to Copy' setting to prevent trades on specific symbols from being replicated on the receiver account.

How to Exclude a Symbol

1. Initially, a trade is opened on a specific symbol (e.g., AUDCAD) on the transmitter account and is successfully copied to the receiver.

2. The symbol (AUDCAD) is then added to the 'Symbols Not to Copy' setting in the receiver account's configuration.

3. Subsequent trades opened on that specific symbol on the transmitter account are no longer copied to the receiver account.

Copying Symbols with Custom Multipliers

The Custom Symbol Multipliers setting allows you to assign specific, individual multipliers to selected symbols on the receiver account, overriding the universal multiplier set for all other trades.

• Custom Symbol Multipliers: This setting allows different multipliers for various symbols, overriding the universal multiplier applied in the receiver settings. If for example a 1 multiplier has been set and in this setting you put: EURUSD2,GBPUSD3.5,USDJPY4 the EURUSD receiver copied trades will be copied with a 2 multiplier, the GBPUSD trades with a 3.5 multiplier and the USDJPY trades with a 4 multiplier, while all other symbols trades will be copied with 1 multiplier. This setting works only when Multiplier or Proportional Multiplier are selected on the Lot Size Type setting above. Also note that any suffixes the receiver account has on its symbols must be included. If for example the receiver account has a .r suffix in its symbols, this setting should be set as: EURUSD.r2,GBPUSD.r3.5,USDJPY.r4

How to Copy Trades with Deriv Volatility Indexes at 0.001 Lot Sizes

To successfully copy trades that use lot sizes smaller than the standard minimum of 0.01, such as those frequently used with Deriv's Volatility Indexes (e.g., 0.001 or 0.0001 lots), you must adjust the following four settings in your EA configuration. This will enable the copying of trades with lot sizes as small as 0.001 or 0.0001. You can find the corresponding set file available here.

Error of Setting Timer in MT4

If you encounter the "Error of Setting Timer in MT4" message when attempting to attach the Local Trade Copier EA MT4© to your chart, the Expert Advisor will fail to initialize properly and will be immediately removed from the chart. This specific error originates from the MT4 terminal itself and is not caused by the Local Trade Copier EA MT4©.

To resolve this issue, follow these steps sequentially:

1. First Attempt: Simply restart your MT4 terminal and reattach the EA to the chart.

2. Second Attempt (If the Problem Continues): Restart your computer or VPS, then reopen your MT4 terminal and attach the EA again.

"Trade is Disabled" Error

If the message "Trade is Disabled" appears in the Experts tab of your receiver MT4/5 Terminal/Toolbox window, it usually indicates one of the following two issues:

1. Broker Restriction

• Issue: Trading has been disabled by your broker for your specific account.

• Action: You must contact your broker directly to investigate and request the activation of trading for your account.

2. Incorrect Symbol Suffix

• Issue: The symbol being copied is not available in the receiver account because the required suffix has not been correctly configured.

• Action:

  1. Open the terminal menu: MT4/5 >> View >> Symbols.

  2. Check the list of available symbols used by your receiver broker to find the correct suffix (e.g., .r).

  3. Include this required suffix in the receiver Local Trade Copier EA's settings:
     Example: If the symbol is EURUSD.r, you should enter: 

Suffix of the Receiver Account: .r

"Unknown Error"

If the message "Unknown Error" appears in the Experts tab of your MT4/5 Terminal/Toolbox, this usually indicates a deeper system or account-level restriction.

Initial Troubleshooting

1. Restart: Restart your computer or VPS.

2. Reattach: Try attaching the Local Trade Copier EA MT4/5© to the chart again.

If the issue continues, it is often due to restrictions imposed by your broker on your trading account.

• Prop Firm Accounts: This error frequently occurs in prop firm accounts where:

  • Expert Advisors (EAs) and algorithmic trading are prohibited.

  • Manual trading rules or competition policies are being enforced.

In such cases, the broker's restrictions prevent the EA from initializing and executing trades.

Error: initialization failed with code 0

If the message "Error: initialization failed with code 0" appears in the Journal tab of your MT4/5 terminal, it indicates that your computer or VPS has undergone an operating system upgrade (such as a major Windows update). This upgrade requires you to reinstall your MQL5.com Market purchases.

How to Fix the Error

You need to force your terminal to re-register the purchased software:

1. Log In: Log in to your MQL5 account via the MT4/5 terminal:

   • Go to Tools >> Options >> Community.

2. Locate Purchases: Navigate to the Market section:

   • MT4: Find the Market tab in the Terminal window.

   • MT5: Find the Market folder under the Navigator window.

3. Reinstall: Locate your purchase (the Local Trade Copier EA) and click the Install button to reinstall the software.

After reinstalling, the EA should initialize correctly.

Error 1003

The error code 1003 typically indicates a general connectivity or download failure when attempting to interact with the MQL5 Market.
