How to Fix Copying Problems with Local Trade Copier EA MT4/5©

Follow these steps carefully:

1. Install the MT4/5 terminal provided by your broker to ensure proper symbol compatibility. Avoid using a terminal from another broker to prevent mismatched symbols or contract details.

2. To set up a second terminal from the same broker, refer to the gif link below. Ensure a unique installation folder during the process.

3. Log in to your MQL5 account under MT4/5 >> Tools >> Options >> Community and install the EA through the Market tab. Never copy/paste EA files, as this will not work with MQL5.com purchases. Stay logged into MQL5 for the EA to function.

4. Confirm the EA version on all terminals (MT4 v4.60, MT5 v4.40). To update, uninstall older versions under Experts >> Market, and reinstall the latest version via the Market tab.

5. Restart your terminals if they have been running for long periods to resolve potential issues.

6. Watch the video below for setup instructions, including suffix handling at 1:30 and special symbol configurations later.

7. If using 'Risk per Trade' options, ensure receiver trades have stop losses. Without this, trades won’t be copied due to missing lot-size calculations.

8. On a VPS, check the Journal tab for error logs. Some VPS services may face MQL5.com restrictions, as with Zomro.

9. The copying of trades from transmitter accounts subscribed to MQL5.com Signals, AVA Copy Trading, or TitanFX Social Trading has been disabled. 

Try these additional steps if the issue remains unresolved:

1. Remove the EA from both terminals.

2. Restart your VPS or computer, then relaunch both terminals.

3. Log into your MQL5 account again and reinstall the EA from the Market tab. Do not transfer EA files manually.

4. Manually adjust transmitter/receiver settings without reloading old set files from prior EA versions. Include suffix changes if needed, then save new settings for the current version.

Still facing issues?
Check the Journal and Experts tabs of your receiver terminal for error messages. Share full screenshots of both terminals (with Marketwatch visible) and your receiver settings as a set file.

What to Do When Both Accounts are from the Same Broker, and You Only Have One Terminal? 

To copy trades between transmitter and receiver accounts from the same broker, you must install an additional MT4/5 terminal from that broker on your Windows PC or VPS. Download the terminal’s installation .exe file from the broker’s website and select a unique destination folder in the Program Files directory for this second terminal during installation. This setup ensures you can run both accounts simultaneously. 

1 Trade from Transmitter Duplicates as Multiple Trades on Receiver

If you notice multiple copied trades in your receiver account(s), it’s likely due to having multiple instances of the Local Trade Copier EA MT4/5© attached on different charts in either the transmitter or receiver terminal. 

Attach only one Local Trade Copier EA MT4/5© to one chart (any symbol) on the transmitter account, and only one on a chart (any symbol) on the receiver account to ensure all trades are copied correctly. 

Refer to the quick setup video, especially after 1:30 for suffixes and the third part for copying special symbols. 

Why Receiver Trades Close Immediately 

This issue often arises when multiple Local Trade Copier EAs MT4/5© are attached to different charts in the transmitter or receiver terminal, or when another copier or multiplier EA is active in the receiver terminal. Ensure that only one Local Trade Copier EA MT4/5© is running on a single chart (any symbol) in the receiver terminal. Check the Experts tab logs of the receiver account for more information. 

Copying Signal Subscription Trades Not Allowed 

MetaQuotes has recently implemented a restriction preventing the copying and multiplying of trades from signal subscriptions. This change affects the Local Trade Copier EA MT4/5©, and any other copier tools, rendering them unable to copy or multiply trades from signal subscriptions. 

Read more details here: https://www.mql5.com/en/forum/473035

Terminal: MQL5 functions related to trading and history will be blocked when a signal subscription is active on the account. Any signal subscription will prohibit the use of MQL5 trading functions, including order retrieval, trade history, and execution. 

VPS Rounding Error 

A known bug with certain VPS setups affects the MathRound function, resulting in a lot size defaulting to 0.01. This problem is linked to the physical CPU of the VPS. Changing to another processor within the same server often fixes the issue, as reported by users. It’s a good idea to avoid VPS configurations where this error occurs.

Ask your current provider for a new server before switching to another VPS service. The issue might only exist with specific CPUs from the same provider. Testing your copier setup on a home computer or a different VPS can also help pinpoint the issue.

Resolving Copying Delays and Missing Trades 

Local Trade Copier EA MT4/5© is designed for fast local trade synchronization and can typically synchronize trading activity between local MetaTrader terminals in under 0.5 seconds under suitable conditions. Final receiver execution is handled separately by the receiver's broker.

If you notice delays or missing trades, the issue may stem from poor communication between terminals or inadequate system capacity. Frozen charts indicate that your setup needs upgrading.

Recommended VPS specifications:

• 2 Terminals: 2 CPU Cores, 4 GB RAM

• 3-5 Terminals: 4 CPU Cores, 6 GB RAM

• 7-8 Terminals: 6 CPU Cores, 12 GB RAM

• 10-15 Terminals: 8 CPU Cores, 16 GB RAM

• 30+ Terminals: 16-24 CPU Cores, 48-64 GB RAM

Additional VPS considerations:

• Broker connectivity: A stable, low-latency connection between each MetaTrader terminal and its broker can help reduce network-related delays during broker communication and execution.

• Disk space: Ensure at least 50-100 GB of SSD storage is available.

• Operating system: Use a compatible Windows Server OS for optimal performance.

VPS specifications can be tricky, a server that looks powerful on paper may underperform if its cores are virtual. I’ve seen traders have smoother operation on reliable, real-core VPSs than on over-advertised virtual ones.

By optimizing these settings, you can avoid delays and missing trades.

Copying Between 1 Transmitter and 1 Receiver Without Suffixes 

Watch this video for a simple 1 transmitter to 1 receiver setup where no suffixes are present in the account symbols. A symbol suffix is any additional letter or group of letters at the end of a symbol, such as '.r' in EURUSD.r. 

Copy Setup with 1 Transmitter and 1 Receiver - Transmitter Symbols with .r Suffix 

In this video, we show a basic 1 Transmitter to 1 Receiver setup, where the transmitter account has a .r suffix on its symbols. The suffix is automatically mapped, so no further configuration is required. A suffix is an extra letter or group of letters at the end of a symbol, such as '.r' in EURUSD.r. The automatic mapping only works for suffixes with a dot, like EURUSD.r, but not for EURUSDecn or EURUSD+. 

1 Transmitter to 1 Receiver Setup - Transmitter Account with Non-Dot Suffix 

Watch this video to learn how to configure a simple 1 Transmitter to 1 Receiver setup when the transmitter account symbols have a + suffix. In this case, you will need to input the + suffix from the transmitter symbols into the Suffix of the Transmitter Account setting on the receiver account. A suffix is typically a set of letters added to the end of a symbol, like .r in EURUSD.r. 

1 Transmitter to 1 Receiver Setup - Receiver Account with Suffix 

In this video, you’ll watch a simple 1 Transmitter to 1 Receiver setup when the receiver account symbols have a suffix. The suffix of the receiver account symbols must be input into the Suffix of the Receiver Account setting of the receiver account. A suffix is a letter or set of letters added at the end of a symbol, like .r in EURUSD.r. 

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

In this video, you will see a 1 Transmitter to 1 Receiver account setup where both accounts use the same symbol with the same suffix (EURUSD.r). The suffix is mapped automatically, allowing for smooth trade copying. If the suffix is not automatically mapped, you will need to manually add the .r suffix in the Receiver Account settings. This issue can arise with brokers offering multiple symbol sets. 

Suffix of the Receiver Account: .r

The suffix is the extra part added to the symbol, such as .r in EURUSD.r. 

Copy from 1 Transmitter Account to 1 Receiver Account - Resolving Different Suffix Issues 

This video guides you through a setup involving transmitter and receiver accounts that use different suffixes. For instance, the transmitter has a + suffix, and the receiver has a .r suffix. Both suffixes should be input in the Suffix of the Transmitter Account and Suffix of the Receiver Account fields within the receiver's setup. A suffix is any letters added to a symbol’s end, like the .r in EURUSD.r. Keep in mind that transmitter suffixes with a dot, such as EURUSD.r, are mapped automatically, but suffixes like EURUSDecn or EURUSD+ require manual entry. 

Copy from 1 Transmitter to 2 Receivers, Dot Suffix on Transmitter Account 

This setup video features 1 transmitter account and 2 receiver accounts. The transmitter account has symbols ending with the .r suffix, which are automatically mapped to the receiver accounts without requiring manual input. A suffix refers to letters added at the end of a symbol, such as the .r in EURUSD.r. Note that automatic suffix mapping works only for dot-based suffixes like EURUSD.r, not for alternatives such as EURUSDecn or EURUSD+. 

Copy from 1 Transmitter to 2 Receivers, One Receiver Uses a Suffix 

Here, you’ll see how to configure 1 transmitter account and 2 receiver accounts, where one of the receiver accounts has a suffix. The suffix must be set in the Suffix of the Receiver Account field for proper operation. For example, the suffix in EURUSD.r is the .r appended to the symbol. 

Copy Setup: 2 Transmitter Accounts to 1 Receiver Account, 1 with Suffix 

Here, a configuration with 2 transmitter accounts and 1 receiver account is presented. One transmitter account includes a .r suffix in its symbols, which is automatically mapped to the receiver account, requiring no manual settings. A suffix is an additional letter or set of letters at the end of a symbol, like the .r in EURUSD.r. Note that automatic suffix mapping is only available for dot-prefixed suffixes such as EURUSD.r and does not apply to suffixes like EURUSDecn or EURUSD+. 

Copy from 2 Transmitter Accounts to 1 Receiver Account, with Receiver Suffix 

Here, you’ll see a setup involving 2 transmitter accounts and 1 receiver account. The suffix used by the receiver account symbols must be added to the Suffix of the Receiver Account setting. For example, in EURUSD.r, the suffix is .r. 

Copying from 2 Transmitter Accounts to 2 Receiver Accounts 

In this video, you’ll learn how to configure a basic copying setup involving two transmitter accounts and two receiver accounts. 

Copying Fails Due to Receiver Account in Investor Mode 

This video highlights an attempt to copy trades from a transmitter to a receiver account. The process initially failed because the receiver account was logged into with the investor password, which provides view-only access. When the user logged in using the master password and re-enabled the Auto/Algo trading button (disabled because of the password change), the copying functioned correctly. 

No Copying with Unsupported or Restricted Brokers

In some cases, copying problems can be related to the broker or trading environment rather than Local Trade Copier EA MT4/5©. Certain brokers may use unusual trading infrastructure, restrictions or account configurations that prevent normal MetaTrader trade information from being accessed or copied.

If trades cannot be copied despite a correct Local Trade Copier EA MT4/5© configuration, check whether the broker and account operate normally within MetaTrader and review the Experts and Journal logs for relevant messages.

3-Account Configuration: 2nd Account as Receiver and Transmitter 

This video explains how to set up 3 accounts. The 1st account sends trades to the 2nd, which receives and then transmits to the 3rd. The 2nd account requires 2 Local Trade Copier EAs MT4/5© on two different charts. 

Configuring Copying of Indexes with Suffix and Symbol Differences 

This video demonstrates 1 Transmitter Account copying US stock market indexes to 2 Receiver accounts with distinct configurations. The 1st receiver account has a .r suffix for US500 and US30, which must be set in the Suffix of the Receiver Account. The 2nd receiver account uses SPX500 and WS30 instead, requiring these symbols to be configured in the Special Symbols section. 

Mapping Stocks Between Brokers with Special Symbols Feature 

Discover in this video how to copy stocks between brokers using the Special Symbols setup in Local Trade Copier EA MT5. The transmitter Tesla stock, TSLA.NAS, is automatically mapped to the receiver account because of its dot suffix. For ABBV.NYSE, the receiver’s Special Symbols settings are applied to align it correctly with the ABBVIE receiver broker symbol. 

How to Exclude Magic Numbers from Copying 

This video explains the process of stopping trades with specific magic numbers from being copied to the receiver account. These trades may come from an EA or another tool with a distinct magic number. You can identify the magic number by hovering over the trade’s ticket number in the Trade or Trading History tab (Expert ID) of the transmitter account. Initially, trades from the Manual Trade Panel EA MT4 are copied. Once the magic number is added to the Magic Numbers Not to Copy setting, new trades from this expert are not copied. 

Managing Symbols Not to Copy 

Learn in this video how to exclude specific symbols from being copied to the receiver account. At first, a trade is opened on the transmitter and successfully copied to the receiver, but after including the symbol in the Symbols Not to Copy list, it is no longer copied. 

Overriding Universal Multipliers for Specific Symbols 

This setting allows you to specify custom multipliers for particular symbols on the receiver account, overriding the universal multiplier. 

• 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 Move an MT4/5 Trade Copier Setup to a New Computer 

To transfer your MT4/5 transmitter and receiver terminals to another computer or VPS with open trades intact:

• Open the receiver terminal on the original setup. Go to MT4 >> File >> Open Data Folder >> Profiles folder and find the gvariables.dat file.

• Copy and save this file.

• Install and set up the MT4/5 transmitter and receiver terminals on the new computer or VPS.

• Replace the gvariables.dat file in the Profiles folder of the new receiver terminal with the copied file (MT4 >> File >> Open Data Folder >> Profiles).

This process preserves the required receiver data so that transmitter-to-receiver trade copying can continue correctly on the new system.

Relocating MT4/5 Transmitter to MT5 Receiver Setup to Another Computer/VPS 

If you’re moving your MT4/5 transmitter and MT5 receiver setup with open trades to a new computer or VPS, here’s how to do it while keeping trade copying functional:

1. Find gvariables.dat File on Current MT5 Receiver Terminal: Launch the MT5 receiver terminal. Navigate to MT5 >> File >> Open Data Folder >> Bases folder and identify the gvariables.dat file.

2. Create a Backup: Copy the gvariables.dat file and store it in a secure location.

3. Set Up the Terminals on the New Machine: Install MT4/5 transmitter and MT5 receiver terminals on your new system.

4. Locate gvariables.dat File on the New Receiver: Open the MT5 receiver terminal on the new system. Navigate to MT5 >> File >> Open Data Folder >> Bases folder.

5. Replace the File with the Backup: Replace the gvariables.dat file in the new setup with the backed-up file from the previous receiver terminal.

6. Verify and Resume: With the migration complete, trade copying should continue seamlessly.

Enable Copying for Deriv Volatility Indexes with Lot Sizes as Small as 0.001 

If your goal is to copy Deriv Volatility Index trades with a lot size of 0.001 or smaller, you need to adjust four important settings to 0.0001. The set file to facilitate this setup is available here.

Error of Setting Timer in MT4

This error may occur when you attempt to attach the Local Trade Copier EA MT4© to a chart in your MT4 terminal, causing the EA to fail initialization and be removed from the chart. The issue is related to the MT4 terminal itself and not the Local Trade Copier EA MT4©. To resolve it, restart your MT4 terminal and reattach the EA. If the problem continues, restart your computer or VPS, reopen the terminal, and reapply the EA. 

Trade is Disabled

This message in the Experts tab of your receiver MT4/5 Terminal/Toolbox window may indicate:

1. Your broker has disabled trading for your account. Reach out to your broker to activate trading.

2. The receiver broker uses a suffix for symbols, causing the copied symbol to be unrecognized. Check the receiver broker’s symbols in MT4/5 >> View >> Symbols and update the 'Suffix of the Receiver Account' setting in the receiver Local Trade Copier EA. For instance, if the symbol is EURUSD.r, configure it as:
   
   

Suffix of the Receiver Account: .r

Unknown Error

When you encounter this error in the Experts tab of your MT4/5 Terminal/Toolbox, restarting your computer or VPS and reattaching the Local Trade Copier EA MT4/5© may resolve it. If it doesn’t, your broker may have applied specific limitations.
