Hi, I am looking for a quote service that provides the EDGX/EDGA books broken down, not just the ISE quote. Esignal does not offer it. Townsend doesn't either. Not sure where to look next. Any thoughts or leads appreciated.
Why would you want this? You are better off with NYSE open book. But if this is what you want, I would go here http://www.directedge.com/API.aspx?s=subscriber and ask them directly.
