I just received info on VTrader brokers who don't use CMS servers. This is an email from [email protected] :

QuoteDislikedNo we do not trade with CMS as their platform tends to freeze during news announcements. We actually trade with Richmond FX of Switzerland , who use the same platform that both FX Asia and CMS use. My understanding is that FXAsia and Richmond FX use the same servers in the US , but these servers are not the ones used by CMS.
