How would I add symbols for the MT4 app for Android which was downloaded from the Play Store created from "metaquotes.net"?
The symbols that I want to add are not listed on the "symbols list".
I want to add GBPAUD, GBPNZD, NZDCAD, and 2 other symbols.
The pairs available are subject to your broker, not Metaquotes. You should speak with them, even though the pairs you mention are quite common.
Check more carefully, because most brokers have different categories for pairs: forex major, forex minor etc.
You should now see the additional currency pair you just added.
Just repeat the adding of the currency pairs until you have all the ones you want that are available.
If you don't see them as available pairs from the "ADD / REMOVE" screen, then you will need to ask your broker to make them available.
Yes, but you have logged in with a broker's account, haven't you?
So, the symbols (pairs) you see available, are those permitted by your broker.
You should speak with them.
Not all pairs are available in all brokers, you should contact your broker and ask him if it offers these other pairs.
