Introduction
- Simple & Reliable Trade Copier that mirrors trades between accounts.
- One EA, Two Roles, same file works as Master or Slave, just flip a setting.
- Copies both Market Orders and Pending Orders, not just live positions.
- Built-in Risk Controls so the Slave account never blindly mirrors lot size.
- No Disruptive Panel to complicate charts, runs quietly in the background.
- Survives Restarts, relationships between Master and Slave trades are saved and reloaded automatically.
Main Function
- Attach one EA as Master on the source account, and one as Slave on the destination account(s), trades flow automatically between them.
- Lot Size Scaling via multiplier, with an optional equity-based risk cap and a hard maximum lot ceiling for safety.
- Symbol Filtering lets you choose exactly which instruments get copied, or block specific ones outright.
- Partial Close Mirroring, when the Master partially closes a position, the Slave proportionally reduces its own position to match.
- Orphan Cleanup automatically closes any Slave trade that no longer has a matching Master trade, keeping accounts in sync.

Disclaimer
This Expert Advisor (EA) is a trade copier tool only, it replicates trades between a Master account and one or more Slave accounts. It does not generate its own entry signals; it copies trades that already exist or are placed on the Master account, whether as Market Orders or Pending Orders.
Trading Forex, CFDs, and other leveraged instruments carries a high level of risk and may not be suitable for all investors. Past performance, backtest results, or strategy outcomes are not indicative of future results. The use of this EA does not guarantee profit and does not eliminate the risk of loss.
The buyer is solely responsible for:
- Testing the EA thoroughly on demo accounts (both Master and Slave) before live use.
- Verifying input settings are correct for their intended instruments, broker, account, and risk parameters (lot multiplier, risk %, max lot size, symbol filters, etc.).
- Ensuring the shared file location/sync setup between Master and Slave terminals is configured correctly and remains reliable.
- Monitoring all trades on both Master and Slave accounts, as no software can guarantee uninterrupted operation or perfect synchronization (e.g. due to platform disconnection, broker server issues, internet outages, VPS downtime, file-sync delays, or differences in execution/slippage between accounts).
- Understanding that any trade, error, or risk on the Master account will be replicated to the Slave account(s), including unintended trades, oversized positions, or strategy mistakes.
