I used to day trade back in the day and have recently started up again. Sheesh, all these new ECN's, hidden ECN's proactive ECN's are making my head spin. I was told by a rep at lightspeed that RASH orders are your best bet for getting filled on a hidden order( I used to use hidden ISLD). Although this DOES NOT seem to be the case. I'm constantly seeing prints go off through my price and I find it damn near impossible to get filled in some of the thinner stocks that I trade. Is there a resource I can look at which would help me get familiar with all these ECN's and what does what type of thing? Anyone know the difference between RASH and hidden ISLD? Thanks for all your help guys and best of luck!
