The following charts are of the stock EMCOR Group (symbol EME) right after market open on September 7, 2012. Best bids and asks are triangles color coded by exchange. The gray shaded area is the National Best Bid/Offer (NBBO).

And this is how it sounds in real-time:

Suggested names:

2. EME Tick Chart

3. EME 2 millisecond interval chart showing 2 seconds of data
Double Arrow

4. EME 25 millisecond interval chart showing 27 seconds of data
Notes the quote message spikes. 

5. EME 1 second interval chart
