A trend line is a line drawn on a chart that shows the general direction in which a particular data series is moving. It is used to help identify and visualize trends in data over time. Trend lines can be used in various fields such as finance, economics, and statistics to help analysts understand patterns and make predictions about future outcomes. Trend lines can be either upward (indicating an increasing trend), downward (indicating a decreasing trend), or horizontal (indicating a stable trend). They can also be used to support decision-making processes and guide investment strategies.
