X_Trader is from Trading Technologies. Are you asking about X_Trader, or Velocity Futures which offers X_Trader as a platform? I have used X, but not Velocity Futures.
i have an account with velocity, they offer xtrader and xtrader pro which is a product of trading technologies, see http://www.tradingtechnologies.com/products/index.html
You needed to be set up on a VPN, most cable and dsl services only offer dynamic IP's and you would need a static in order to set up a VPN
According to GHCO, one does not need a static IP to use their VPN and X_TRADER. I had a dynamic IP for my DSL connection to X_TRADER which, BTW, was very stable.
That is great and yes according to GHCO you can be set up w/o a VPN but the troubles listed in the prior e-mail have come up for some of my clients in the past running on a dynamic IP.
I have no doubt that Speedracer and some of your clients experienced problems running on a dynamic IP, and that is a real shame if they were promised otherwise.
