Trend analysis
From ACT Wiki
Trend analysis is based on reviewing historical price data, often for the purpose of predicting future price changes based on assuming the continuation of historical trends. Trend analysis is an important aspect of Technical analysis.
In a simple trending process, the correlation coefficient between successive periods' price movements is positive. In other words, there is a greater probability that a subsequent price movement will be in the same direction as the previous period's movement (rather than in the opposite direction from the previous period's movement).
