Volume!

Hi Pat, Love your work and love this site! Ive only been a member for 2 months, but it's very clear to me that reading the volume is absolutely fundamental in what we do here.  I'm just trying to work out the best way to read volume during open markets before entering a trade. Its easy to look back after markets close.. But Is it important to have access to level 2 and do u have any good tutorials you can point me to tgst specifically focuses on volume?    Kind regards  Paul (Brighton-UK)
