Best Gen3 broker for autotrading FX

Hi,



I currently autotrade an S&P e-mini system with OptionsXpress and so far it has gone fine.



Can anyone recommend an FX broker that will allow me to Gen3 autotrade.



I have seen the table listing which brokers offer Gen3 FX trading but I’m after recommendations of good brokers or ones to avioid.



Thanks in anticipation.



Dan
