Level II size alerts scan for Market Makers that display size on the bid or ask.  
When a Market Makers shows size on the bid/ask , it can mean a level of support/ resistance 
and it can also mean a head fake.  Either way large size on the bid/ask attracts attention from 
traders and movement in the stock, which is often good for quick scalps.
