Quote from Rickshaw Man:
Your point is meaningless, as all FX quotes are different since their is no central exchange.
Why on earth would anyone view quotes from another source other than their broker.
When I put an order in my broker is not going to execute my order biased on what another data provider is quoting.
When the broker is not the market, as is the case in interbank Forex dealing you needs feeds reflecting the interbank market.
Retail FX brokers can and will control the data feed if needed. They are the "house" not the market.
So I guess it you are interested in playing a FX game you can work with your brokers data. If you are interested in the FX market, you need market data. The good ones work with multiple source feeds.
