Trend Line

A trend line is a straight line drawn on a price chart connecting two or more points where a stock's price has touched, showing the general direction the stock is moving. You'll see these all over technical analysis—the practice of studying price charts to predict future moves. Trend lines matter because they help you spot whether a stock is in an uptrend (moving up), downtrend (moving down), or sideways, and they can signal when that trend might break. For example, if TechCorp's stock price bounces off a rising trend line three times without breaking below it, that line becomes a level traders watch closely. When the price finally breaks through, it often sparks buying or selling.
