It is incredibly helpful for both five minute price action chart reading and for identifying the top and bottom of trends on a hourly or a session movement. You can identify where buyers and sellers are, and enter on the next bars with confirmation, with very good risk to reward ratios. Compared to all the indicators out there and on many people's charts, VSA has more value IMHO. That other famous forum on the web (not sure if I'm permitted to mention) has tons of excellent info. Reading Mastering the Markets (many times!) is a good idea, but even without that, you can get a good sense for identifying setups.
