FYI, Level II is quotes only feed. Trades reported on primary/regional exchanges only.
1. Most likely you will see trades from all market centers your broker has marked feed from. With professional feed, you can subscribe for...
I disagree. How many time have you seen the price going up on the light volume attracting more and more buyers, and then going down heavily...
No it's not (repeating this for the second time). Please, do the research. As the part of the NBBO feed you get the exchange codes that posted...
This is the right sequence (at least for NYSE). Keep in mind that the picture maybe something like this in the fast moving market: 20.50 x...
