its been okay to be fair - bit wider than normal but that is fine. Lava been better but not so much size available and I don't like the platform as much (not single click etc) EBS also been ok on euro doll and doll yen but awful on cable, as always!
I noticed no slowing with Currenex, but I use FIX, not their GUI. Liquidity has gotten worse, at least for me, recently. Both HotspotFXi and IB have had better spreads than at Currenex. Not sure why, as they used to be comparable.
