I have good execution software but the quote software sucks ass. I can get a good NYOB feed through esignal, but they have no consolidated ECN book. I just trade NYSE, and I'll pay a premium if it's worth it, but I need to see the NSDQ book, the arca book, the bats,edgex,edga books, and all the market makers, as well as the inside NYS quote. What standalone dataproviders provide that data at raesonable costs and the fastest possible speeds?
What you're looking for is Nasdaq TotalView, which I believe can be found through these providers: https://www.nasdaqtrader.com/asp/totalview_about.asp $15 per month for non-professionals and $76 per month for professionals, plus a mark-up or platform fee depending if they have one.
