I plan on trading through an online broker. Does anyone know a way to receive NYSE Open Book info on a stand alone basis without subscribing to a more comprehensive quoting package such as E Signal etc.?
You can subscribe to Open Book at IB (via the NYSE) and see the open book info via the TWS. Instructions on how to subscribe can be found via the market data subscription info on the account login page. just click on openbook for the details.
seth, i don't know about instinet but will ask as well.
