Trendlines can create a sense of support or resistance for traders. When the price reaches a trendline, traders may be more likely to buy or sell, depending on the direction of the trend. This can create a self-fulfilling prophecy, where the price actually does follow the trendline.
The price may break through a trendline, which could signal a change in trend.
