ATC EA Mode
Copy trades directly between MetaTrader terminals using ATC's Expert Advisor
Overview
EA Mode lets you copy trades using Expert Advisors (EAs) installed directly on MetaTrader 4 or MetaTrader 5 terminals — no external node or server required. A Master EA runs on the signal provider's terminal and broadcasts trade signals, while a Slave EA runs on each receiving account and replicates those trades in real time.
This mode is ideal for traders who want a lightweight, self-hosted setup without relying on ATC's cloud infrastructure.
For a server-managed alternative that doesn't require running your own terminal 24/7, see Node Mode.
How It Works
Install the Master EA
Attach the ATC Master EA to a chart on the account you want to copy trades from. This is typically your signal provider or prop firm evaluation account.
Install the Slave EA
Attach the ATC Slave EA to a chart on each account you want to copy trades to. Enter the connection details provided by the Master EA to link the accounts.
Configure Lot Sizing & Risk
Set your lot multiplier, risk mode (fixed lot, multiplier, or balance-proportional), and any symbol filters or overrides before going live.
Enable AutoTrading
Make sure AutoTrading is enabled on both terminals. Trades placed on the Master will now mirror to all connected Slave accounts within milliseconds.
Requirements
- MetaTrader 4 or MetaTrader 5 terminal (Master and Slave can be different platforms)
- Both terminals must remain open and connected to their brokers
- AutoTrading / Algo Trading permissions enabled
Common Settings
| Setting | Description |
|---|---|
| Lot Mode | Fixed, Multiplier, or Balance Ratio |
| Symbol Mapping | Map differing symbol names between brokers (e.g. XAUUSD → GOLD) |
| Reverse Trading | Copy trades in the opposite direction |
| Max Slippage | Maximum allowed price deviation before a trade is skipped |
Both terminals need a stable internet connection. If the Slave terminal disconnects, trades placed during the downtime will not be copied retroactively.
