My reco's for futures brokers are:
For trading software, I continue to use and recommend T4.

It is not the cheapest software around, but the speed and hosting is top of the line. By hosting I mean that your orders are actually stored at CTS Futures (designers of T4). Should your internet go down and/or the exchange, your orders are still working. For me, that is very important as internet outages are inevitable. By holding your orders on their servers, they are able to offer additional services, such as MIT (Market If Touched) orders whereas some software packages cannot do that b/c the order resides at the exchange and some exchanges do not support MIT's or other certain types of orders. Mirus and ProActive both currently support T4, although it may be referred to under a different name. Mirus calls the platform Dorman Direct and ProActive currently calls it T4.
Note - Open ECry supplies their own trading software at no cost, which is an attractive option depending on your needs. The platform is nice as well, so it's a great option, esp for those looking for inexpensive platforms.
