Hi guys, I am moving my currency trading away from a spot fx dealer and I am exploring two marketplaces: Globex futures through Open E-Cry or Velocity and Currenex via PropFX. I am demoing both environments and the costs of trading appear to be the same - a mixture of tight spread + low r-t commission. Which marketplace, however, is better when it comes to buying on the bid and selling on the ask? I guess it's a matter of liquidity. Any comments?
