Symbols Mapping is used if the symbol difference between the master and slave is too complex.

By default, our Trade Copier is able to automatically define the suffix by itself. For instance EURUSD to EURUSDm or USDCHF to USDCHFpro,. However, for complex symbols like XAUUSD to Gold or XTI to Oil, etc. you will need to use the "Symbols Mapping" functionality. It will allow you to define which Master symbol corresponds to which Slave symbol.
To map, you would need to enter the EXACT symbol of the Master and the Slave. Please note that mapping is case-sensitive. 

If you wish to define a different setting for a specific symbol, please read our tutorial about Symbol Settings.
