MirrorForge Copie MT5

MirrorForge Local MT5 Trade Copier

MirrorForge is a local MT5 trade copier designed to mirror trading activity from a Master account to a Slave/Target account using a file-based communication system.

The EA can copy open market positions and pending orders, synchronize Stop Loss and Take Profit levels, support different lot-sizing configurations, handle broker symbol differences through prefix/suffix mapping, and maintain Master-to-Slave ticket relationships across terminal restarts.

MirrorForge also includes a modern on-chart control panel with copying controls, synchronization information, account statistics, Master heartbeat status, symbol filters, and an emergency Close All Copied Trades function.

The system is designed for traders, EA developers, money managers, signal providers, and users who need to mirror trades between MT5 terminals running on the same computer, VPS, or environment where the MT5 common files directory is accessible.

Key Features

Master and Slave Modes

MirrorForge operates in two modes:

Master Mode

• Monitors the source MT5 account.

• Writes the current trading state to a shared file.

• Publishes open positions.

• Publishes supported pending orders.

• Publishes entry price, volume, Stop Loss, Take Profit, magic number, comment, setup time and expiration information.

• Maintains a heartbeat file so the Slave can determine whether the Master is active.

Slave Mode

• Reads the Master trading state.

• Creates corresponding trades on the target account.

• Maintains Master-to-Slave ticket mappings.

• Detects when Master positions are closed.

• Detects when Master pending orders are removed.

• Updates copied Stop Loss and Take Profit levels.

• Reconciles the account after terminal restarts.

Both terminals use the same File ID to establish the communication pair.

Copy Market Positions

MirrorForge can copy open market positions from the Master account to the Slave account.

Supported directions include:

• Buy positions

• Sell positions

You can independently enable or disable copying of Buy and Sell trades.

The Slave can either follow the Master trade direction or reverse it.

Example

If the Master opens:

BUY 0.10 EURUSD

The Slave can be configured to open:

BUY 0.10 EURUSD

or, with Reverse Trades enabled:

SELL 0.10 EURUSD

Copy Pending Orders

MirrorForge can also synchronize supported pending orders.

Supported pending order types include:

• Buy Limit

• Sell Limit

• Buy Stop

• Sell Stop

• Buy Stop Limit

• Sell Stop Limit

The Slave monitors the Master pending-order list and attempts to maintain the corresponding pending orders.

If a pending order is modified on the Master, MirrorForge can update the corresponding Slave order.

If the Master pending order disappears, the mapped Slave pending order can also be removed.

Pending-order copying can be enabled or disabled independently.

Stop Loss and Take Profit Synchronization

MirrorForge can copy the Master trade's:

• Stop Loss

• Take Profit

These settings can be controlled independently.

Stop Loss

Enable:

Copy Stop Loss = true

The Slave will use the Master Stop Loss when opening or modifying the copied trade.

Disable it when you want the Slave to manage Stop Loss independently.

Take Profit

Enable:

Copy Take Profit = true

The Slave will use the Master Take Profit.

This provides flexibility for traders who want the Slave to follow the Master completely or use their own risk-management approach.

Flexible Lot Sizing

MirrorForge provides several lot-sizing options for Slave trades.

Fixed Lot

The Slave can use a predefined lot size regardless of the Master position volume.

Example:

Master:

0.50 lots

Slave Fixed Lot:

0.01 lots

The Slave opens:

0.01 lots

Lot Multiplier

The Slave can calculate its position size using the Master position volume multiplied by the selected multiplier.

Formula:

Slave Lot = Master Lot × Lot Multiplier

Example:

Master:

0.10 lots

Multiplier:

2.0

Slave:

0.20 lots

A multiplier below 1.0 can also be used to reduce the copied position size.

Lot Limits

The EA provides:

• Minimum Lot

• Maximum Lot

These settings help prevent the copier from opening positions outside the configured lot range.

The EA also checks the broker's symbol volume settings, including:

• Minimum volume

• Maximum volume

• Volume step

before sending the trade.

Reverse Trades

The Reverse Trades option allows the Slave to trade in the opposite direction of the Master.

When disabled:

Master BUY → Slave BUY

Master SELL → Slave SELL

When enabled:

Master BUY → Slave SELL

Master SELL → Slave BUY

The reverse-direction functionality also applies to supported pending order types.

This allows MirrorForge to be used for strategies where the Slave account intentionally takes the opposite side of the Master account's signals.

Symbol Mapping

Different brokers may use different symbol names.

For example, one broker may use:

EURUSD

while another uses:

EURUSD.m

or:

EURUSDpro

MirrorForge provides symbol prefix and suffix settings to help map the Master symbol to the Slave broker's symbol.

Available settings include:

• Master Symbol Suffix

• Slave Symbol Suffix

• Slave Symbol Prefix

Example

Master:

XAUUSD

Slave suffix:

.m

Result:

XAUUSD.m

This makes the copier more flexible when Master and Slave accounts use different broker symbol naming conventions.

Symbol Filter

MirrorForge allows you to control which symbols are copied.

The Allowed Symbols input accepts a comma-separated list.

Example:

EURUSD,GBPUSD,XAUUSD

Only the specified symbols will be processed.

Leaving the setting empty allows all symbols.

This can be useful when the Master account trades many instruments but the Slave account should only copy selected markets.

Magic Number Control

Slave trades are assigned the configured MirrorForge Magic Number.

This helps identify trades created by the copier and allows the EA to distinguish its own positions and pending orders from other trades on the Slave account.

The Master also provides an optional:

Copy Only Magic

filter.

When enabled, the Master will only publish positions and pending orders matching the configured Magic Number.

This is useful when another EA or multiple strategies are operating on the Master account.

Maximum Position and Pending Order Limits

MirrorForge includes safety limits for the Slave account.

Maximum Open Positions

Controls the maximum number of copied positions allowed.

Default:

100

Set to:

0

for unlimited positions.

Maximum Pending Orders

Controls the maximum number of copied pending orders.

Default:

50

Set to:

0

for unlimited pending orders.

These limits can help prevent uncontrolled copying if the Master account contains a large number of trades.

Slippage and Retry Protection

MirrorForge includes configurable execution controls.

Maximum Slippage

The:

Slippage Points

setting controls the maximum deviation used for trade execution.

Order Send Retries

If an order fails, MirrorForge can retry the operation.

The:

Max Order Send Retries

setting controls the number of attempts.

This can provide additional execution resilience when temporary trading conditions or broker responses cause an order request to fail.

Fast Local Synchronization

MirrorForge uses millisecond timers for its local synchronization process.

The Slave uses a configurable polling interval.

Default:

250 milliseconds

The Master writes its full current trading state at a configurable interval.

Default:

400 milliseconds

In addition, Master trade transactions can trigger an immediate state update.

This combination is designed to keep the Slave synchronized with changes occurring on the Master account without requiring an external server.

Actual execution speed can still depend on the MT5 terminal, broker, symbol trading conditions, VPS/computer performance, and market conditions.

Master Heartbeat

MirrorForge uses a heartbeat mechanism to monitor the Master.

The Master periodically updates a heartbeat file.

The Slave checks the age of that heartbeat.

Default timeout:

15 seconds

If the Slave does not receive a recent heartbeat within the configured timeout, the panel can report:

MASTER OFFLINE

This allows the user to monitor whether the Master terminal is actively publishing its state.

The heartbeat is a monitoring mechanism; it does not guarantee that every trade can be executed on the Slave.

Terminal Restart Recovery

One of the important features of MirrorForge is its reconciliation system.

The Slave stores Master-to-Slave ticket mappings in files.

When the Slave terminal is restarted, MirrorForge loads the saved mappings and performs a reconciliation process.

This allows the EA to compare:

Master current state

against

Slave current state

and determine which mapped trades should remain synchronized.

The system is designed so that terminal restarts do not automatically mean that the copier loses all knowledge of previously mapped trades.

Existing Trade Synchronization

MirrorForge provides an option for handling trades that already exist when the Slave starts.

Copy Existing Trades = Enabled

The Slave can synchronize existing Master positions and pending orders during startup/reconciliation.

Copy Existing Trades = Disabled

The EA can skip existing Master trades during the initial reconciliation.

This gives the user control over whether the Slave should begin copying only from new activity or also synchronize positions already open when the copier starts.

Automatic Trade Removal Synchronization

MirrorForge continuously compares the Master state with its stored mappings.

If a Master position that was previously mapped no longer exists, the EA attempts to close the corresponding Slave position.

Likewise, if a mapped Master pending order no longer exists, the EA attempts to delete the corresponding Slave pending order.

This keeps the Slave account aligned with the current Master trading state.

Live Modification Synchronization

If a copied Master position has its Stop Loss or Take Profit changed, MirrorForge checks the corresponding Slave position.

If the values are different, the EA can modify the Slave position.

The same synchronization logic is applied to supported pending orders, including their:

• Entry price

• Stop Loss

• Take Profit

This means the copier is not limited to copying the initial trade entry.

Modern Control Panel

MirrorForge includes an on-chart control panel.

The panel displays important information including:

• Current mode

• Master online/offline status

• Account balance

• Account equity

• Open positions

• Pending orders

• Mapped positions

• Mapped pending orders

• Last synchronization time

• Symbol filter

• File ID

The panel can be disabled if the trader prefers a clean chart.

Copying ON/OFF Control

The panel provides a button to enable or disable copying.

Copying: ON

The EA continues its normal synchronization process.

Copying: OFF

The synchronization process is disabled until copying is enabled again.

This gives the user direct control without needing to remove the EA from the chart.

Force Sync

The Slave panel includes a:

Force Sync

button.

This allows the user to manually trigger a synchronization process instead of waiting for the next normal timer cycle.

This can be useful when checking synchronization after changing settings or reconnecting terminals.

Close All Copied Trades

MirrorForge includes an emergency/manual control:

CLOSE ALL COPIED TRADES

When used in Slave mode, the EA attempts to:

• Close positions using the MirrorForge Magic Number.

• Delete pending orders using the MirrorForge Magic Number.

• Clear the stored position mappings.

• Clear the stored pending-order mappings.

This provides a convenient way to remove the copied trades managed by the copier.

Users should understand that this function acts on trades identified by the configured Magic Number, so the Magic Number should be configured carefully.

Detailed Logging

The EA provides a Detailed Logging option.

When enabled, important events can be displayed in the MT5 Experts log, including:

• Position copied

• Pending order copied

• Position closed because the Master position disappeared

• Pending order deleted

• Mapping information

• Synchronization information

• Execution errors

• Master heartbeat status

• Maximum trade limits reached

This can make troubleshooting and monitoring easier.

Recommended Master/Slave Setup

A typical setup consists of two MT5 terminals.

Step 1 — Master

Attach MirrorForge to the account that contains the trades you want to publish.

Set:

Mode = MASTER

Choose a unique:

File ID

For example:

MyCopier

Keep the desired copying filters enabled.

Step 2 — Slave

Attach MirrorForge to the target MT5 account.

Set:

Mode = SLAVE

Use the exact same:

File ID = MyCopier

Configure the desired:

• Lot Mode

• Lot Multiplier

• Symbol mapping

• Buy/Sell filters

• Risk limits

• Stop Loss/Take Profit settings

Step 3 — Keep Terminals Running

For continuous copying, both the Master and Slave terminals need to remain active.

A VPS can be used to keep MT5 terminals running continuously.

The copier does not use an external cloud/server-based copy infrastructure. Communication is performed through files available to the MT5 terminals.

Example Configuration

Master Account

Mode:

MASTER

File ID:

MyTradingAccount

Copy Pending:

Enabled

Copy Buy:

Enabled

Copy Sell:

Enabled

Slave Account

Mode:

SLAVE

File ID:

MyTradingAccount

Lot Mode:

LOT_MULTIPLIER

Lot Multiplier:

0.50

Copy Stop Loss:

Enabled

Copy Take Profit:

Enabled

Copy Pending:

Enabled

Reverse Trades:

Disabled

This configuration would attempt to mirror the Master direction while using approximately 50% of the Master volume, subject to the Slave broker's volume requirements and the configured minimum/maximum lot limits.

Who Can Use MirrorForge?

MirrorForge can be useful for:

• Traders managing multiple MT5 accounts

• EA developers testing strategies across accounts

• Traders using separate Master and execution accounts

• Traders who want to mirror selected instruments

• Users with different broker symbol suffixes

• Traders who need fixed or multiplier-based Slave lot sizing

• Users who need position and pending-order synchronization

• Users running MT5 terminals on a local computer or VPS

Important Technical Notes

MirrorForge is a local file-based copier.

It does not depend on a remote trade-copying server for communication between the Master and Slave.

Both MT5 terminals need access to the appropriate MT5 common files environment.

The actual result of copying can be affected by:

• Broker execution

• Market liquidity

• Spread

• Slippage

• Symbol availability

• Trading permissions

• Minimum and maximum volume

• Volume step

• Stop-level requirements

• Market conditions

• Terminal/VPS performance

• Internet connectivity

• Differences between Master and Slave brokers

A successful Master trade does not guarantee an identical execution price on the Slave.

Risk Warning

MirrorForge is a trade-copying tool. It does not guarantee profits and it does not remove the risks associated with financial markets.

Copied trades can experience differences in:

• Entry price

• Exit price

• Spread

• Slippage

• Execution time

• Stop Loss execution

• Take Profit execution

• Available trading volume

• Symbol specifications

A Master account and Slave account can therefore produce different results even when the same trading instructions are copied.

Users should test the copier on demo accounts before using it with real funds and should configure lot sizes and limits according to their own risk tolerance.

Never assume that copied trades will have exactly the same execution as the Master.

Important Setup Requirement

For successful communication, the Master and Slave should use the same File ID.

For example:

Master:

File ID = MyCopier

Slave:

File ID = MyCopier

Using different File IDs will cause the terminals to use different communication files.

If broker symbol names are different, configure the appropriate Master suffix, Slave suffix, or Slave prefix.
