I did not find the second/3rd pair for Gold on this broker ..But it may be something with the broker anyway -
If it is related to the broker so it can not be fixed.
Do you mean this?
I mean the following:
If you see "symbol not found" error message (but you have this symbol) so it may be because of the following: signal system identified more than one pair for this symbol with suffixes/prefixes).If yes, so nothing you can do except the changing the broker.
