In a scatter diagram, when the dots are distributed roughly along an ascending tendency, there is a positive correlation between the two sets of data. On the contrary, when the dots are distributed rough along a descending tendency, there is a negative correlation. However, when the dots scatter irregularly without a pattern, there is no obvious correlation.

The paper obtains some conclusions after many theories analysis and empirical tests: Firstly, Volume-price relativity is extensive: total volume or it's change, disassembled volume promoting price movement or it's change all has plus relativity to equilibria price. Secondly, there is unilateralisms Granger casuality in bullmarket, while there is bidirectional Granger casuality in bearmarket. There is not nonlinear Granger casuality in both markets. Third, Behavior finance has remarkable effects after contrasting to different investment conditions. Moreover, causality research by moving tendency can reflect the stable relation while usual causality research can't do. Fourth, it can be ture forecasing key period of tendency reversion by building volume-price elasticity coefficient containing composite information of volume-price and analysis methods of moving tendency.
