http://www.nasdaqtrader.com/Trader.aspx?id=MarketDataVendorsList&StartAlphabet=A&EndAlphabet=ZZZ On this page, there are several totalview data feed vendors. How can I get totalview-itch data feed for trading and what is the price? Can I get this data without co-location?
Sterling Trader can show totalview-itch data and does not need to be co-located. I don't know the price. You have to contact your broker.
