I trade an average of 50,000 contracts per month on eurex, mainly Bund. I am looking around for a new broker. Could you please advise a couple of European and a couple of US Brokers that may be appropriate for this kind of volumes? The benefit with an European broker would be to have lower latency times since a ping between my office in Europe and the States takes 100-150 ms according to the US zone I try to reach. Moreover the US broker in turn would have a slower link with Eurex compared to the European broker, always due to the distance. Unfortunately this disadvantage due to the distance cannot be solved. Thanks in advance.
