Does anyone use them with the free version of X-Trader as their front end? I ask this because I currently have an account with Mirus/Ninja Trader - Zen Fire. It's hard for me to believe that Velocity only charges an extra $0.10/RT for US Treasuries using X-Trader, which IMO is far superior to NT given my trading style. You can't even change up the bid/ask/price columns on NT to suit your visual appeal. Not a big fan. Anyways, just wondering if anyone uses Velocity with the free version of X-Trader, and if their quoted commission fee of $3.34 per R/T on US Treasury products is all inclusive...no hidden/additional fees? Thank you in advance.
