I am having the same issue with the forex.com connector, although I am using it with City Index Australia (same firm, different name).
Furthermore, the bid/ask spread for every FX symbol is much wider than what can be seen in the City Index web trader. For instance, AUD/USD shows a spread of 1.9pips right now in Motivewave, but only 0.6pips in Webtrader. It seems like a totally different data feed.
My City Index account is a live account, standard spread. I am waiting on a raw spread account to be created, so I'll test it with that as well when it is completed.
