MetaTrader 4 Demo

 
How can I add more currency pairs to the Demo?  Do I need to open an actual account?
 

You can only trade what your broker allows.
          View (alt+V) → Market Watch (control+M) → right-click → Show All. Or,
          View (alt+V) → Symbols (control+U) → double-click to add.

 
You can trade with the MT4 demo if the broker provides a free demo account, and you can add more currency pairs by navigating to the 'Quotes' tab. Press the '+' button on your phone at the top right-hand corner. This will open a sub-menu. Navigate through these groups until you find the pair you require, and tap to add them to your Quote List.
 
I do not think it is possible to add more value to a demo account since they already provide a huge amount of it and it also depends on the broker because some do not allow it since it is a demo account.
