Symbol mapping: copy trades across different brokers

Different brokers use different names for the same instrument. Symbol mapping tells each slave which of its symbols matches a given master symbol, so every trade lands on the right market — even when your master and slaves are at completely different brokers.

✅

Same names?

If both brokers use identical symbol names, you don't need anything. Leave mapping empty.

🔀

Different names?

Add one mapping line for each instrument whose name differs between the two brokers.

1

Open the mapping

On the Slave Accounts page of your dashboard, click Symbol Mapping on the slave to expand it.

2

Enter both names

Master symbol — exactly as it appears on the master (e.g. US500).
This broker — the matching name on the slave's broker (e.g. US500.cash).

3

Add it

Click Add mapping. From now on, any US500 trade from the master is routed to US500.cash on this slave.

💡

The match is case-insensitive. Find the exact slave name in MetaTrader's Market Watch (right-click → Symbols).

Common mapping examples

Master symbol		Slave broker name
`US500`	→	`US500.cash`
`XAUUSD`	→	`GOLD`
`EURUSD`	→	`EURUSD.m`

⚖️

What about different lot sizes? Mapping is only about names. If a mapped instrument also has a different lot step on the slave broker, the copier rescales the volume automatically — nothing to set up.
