Well if you trade enough your broker will offer them to you, depending what brokerage you have, but if you cant get them free like myself. They are pretty expensive for what it is worth. In fact it's almost useless IMO, a distraction from other more meaningful analysis, L2 is more like a contrarian indicator, since real buyers can use hidden orders and real sellers likewise. So when I see a market maker not hiding his short sales all day long that tells me the opposite of what a newbie investor watching L2 might think. So basically id just keep trading, and see if your brokerage will offer your for free.
