If you have a prefix on your Receiver account (for example, the name of EURUSD pair is aEURUSD), please open Forex Copier 2 program, click “Settings” on Receiver account,
go to “Advanced settings” tab, enter the prefix into “Add this prefix to symbol name of copied orders” field and uncheck “Allow auto adjusting symbol names” option.
If you also have a prefix on Source account please click “Settings” on a Source account, go to “Advanced settings” tab and enter the prefix into “Remove this prefix” field.
Then click "Apply Scheme" button to apply new settings.
Please change prefixes manually only if the automatic adjustment does not work.
By default, Forex Copier should copy orders for the pairs with different prefixes by itself.
