Quote from Xspurt:
Yes it's a tool and you are correct, if you can't understand how to use it then it is useless.
But no, it's not just a tool, any old tool. This is the one that the exchanges and MM's don't want us to have.
Getting correct daily volume is an art because of deliberate attempts to fool us. The MM's and exchanges don't think it's just another tool or they wouldn't go to such lengths to disguise or hide what is happening.
Dark Pools exist because volume talks but it takes time and effort to learn the lingo.
