Nasdaq newbie questions

Hello,

I've never traded nasdaq nor US stocks so don't flame me please...LOL.

For any given nasdaq equities, is there something like a main book like NYSE OpenBook? What is Nasdaq TotalView?

For most nasdaq stocks, what is the ECN, book that gets the most volume? ARCA? What is the ECN usually proposing the NBBO?

Thanks a lot for your help, I am a bit lost with all those liquidity poles...

 

Nasdaq TotalView is like the Openbook. ARCA gets alot of volume along with NSDQ.

 

OK thanks a lot
