VSA (Volume Spread Analysis ) is a particular form of technical analysis which assesses the volume compared to the price action. VSA considers “crowd mentality” and incorporates what the balances of supply and demand will do to the market and when it is likely to move. VSA looks at volumes to establish what the professional players in the market are doing and how prices are being manipulated by volume. It does this by looking at three components: the price versus volume, the closing price and the price range.
