Volume

There may be a very obvious answer to this question, but...where can I see volume in different currency pairs? I normally use Dailyfx.com or FXCM's TSII charts but none have an option to see the volume. Thanks in advance.

Thanks, got the demo downloaded. Now can you tell me where these volume numbers come from?
