jetboy,
i have been using cyber for about 1 year now.. i use the cyberx2 software and Qcharts/Ravenquote.. my biggest compliant with cyber is that their level 2 data doesnt always show all of the participants.. BTRD is the most often one that is left out.. when cybercorp switched to cybertrader they they put me in a "priority access" group which is supposedly for high volume traders.. now if i ever have a stuck order, question, problem with the data or whatever i can just click on the send message button and someone is there to handle it for me immediately.. even when the selectnet system went down a few weeks back and everything was crazy they still answered my message and took care of my problem.. one tip with cyber though.. watch out for ecn fees, those things can get really expensive.. arca, btrd, and brut are all .005 a share.. inca is .015.. but redi is only .002, which is what i use to scoop shares from the other ecns.. Cyber is the only direct access firm that i have used with the exception of MyTrack (which is a POS), so i couldnt comment on how it compares to other firms..
good trading
