Exotic currencies on MetaTrader

Hi there,
Would like to ask if its possible to insert additional currency pair into metatrader other than those that already exists in the system? If so, any one knows where to get these files or codes? (Looking for SGD/AUD, but any others are welcomed too)

Thank You.

Broker needs to support them, find a broker that does.

You may find, as I recently did, that your broker supports all kinds of stuff that you are not seeing when you hit the "new chart button". What you can do to add currency pairs, commodities, CFDs etc. that your broker supports but do not appear in the "new chart" drop down is: click on "market watch" to open the market watch window, right click on the field at the top that says "Symbol", this will open a drop down where you will see the options "Sets" and "symbols" (this part may vary from broker to broker but this is the menu you want to add pairs and symbols) if you select "sets" you will get options for "forex" and "forexall" by selecting these you can add currency pairs that your broker supports by double clicking the desired pair, clicking on the symbols button will bring up another menu from which you can add other stuff as well. You may, however, may still need to shop around for a broker that supports what you are looking for

Meum,
i think that is the long cut.

The shortcut way is:
on the MarketWatch, right click anywhere, & click/check "Show All".

Even better, thanks.
