---So, does one have to subscribe to ArcaBook for Equities, Nasdaq Totalview, and NYSE OpenBook RealTime to get complete aggregate bid/ask volumes, even for Level 1?---
dunno about NY OpenBook and Totalview(i would ask IB),but ARCA-yes. without it -you not going to get anything from ARCA. to add more pain-they now it require separate subscription per user(all this shit use to be free for all, 10 years ago,now-it will cost you a small fortune every month,specially if you qualify as a pro(corp,LLC,etc))
per user mean-if you have an account with IB and there is more than one username\trader on same account-each of them are required to have separate subscription. and each have to pay separately.
