I am going to trade with a firm that has ass sucky data... I need my own third party data to trade from since their in house data simply isn't reliable. I thought I could use esignal, until their reps informed me that I can't see the various level IIs consolidated on listed stocks - I have to have a separate window for Arca, ISLD, etc. Having just the NYOB and a seperate windows for all ECNs is fine. It would be nice if the software had charting, too, but I just need reliable LII data for listed stocks. What company gives this?
