Hi all, I have just started a relationship with a prime of prime and am trying to select the best ECN. They offer a lot of options but I chose Hotspot to start because I have some familiarity with it. Anyways, I've used for a few days and I'm not impressed. The last look feature leads to a lot of crummy fills. I'm not trading huge - one click trading on 1-5 mio unit amounts. Does anyone have experience with some of these quasi-institutional ECNs (currenex, fxall etc). Thanks!
