Yep, read through the thread that
gypaetus suggested (click on the link) from the beginning, as a large part of it is dedicated to VSA analysis.
If and When you don't understand a principle (or something) come to the end of the thread and ask the question. Then when you have an answer and understand, go back and continue through the thread. Don't hurry through it, especially if you have not been exposed to VSA much in the past, as it will be a lot to take in all at once. it is even worth taking a break from time to time, as quite often when you come back after a short break, you may have a 'light bulb moment' (so to speak).
Good Luck with your learning, try to read Master the Markets at least once (more times of possible), there are plenty of free downloads of it on the net, don't spend any money on anything straight away, and I can't stress enough, to ask questions. I am usually around and will answer pretty quickly, and if I am unavailable for some reason, some of the other members will also help out I'm sure.
cheers
