Trendline
A trendline is a straight line drawn on a price chart to show the general direction of an asset’s movement.
A trendline is a simple technical analysis tool used to connect key price points on a chart, usually swing lows in an uptrend or swing highs in a downtrend. In crypto markets, traders use trendlines to make the direction of price action easier to see, filtering out some of the noise from short-term volatility. An upward trendline suggests buyers are stepping in at progressively higher prices, while a downward trendline suggests sellers are pushing prices lower over time.
Trendlines matter because they can highlight possible support, resistance, and changes in market momentum. For example, if Bitcoin has bounced several times from a rising trendline, traders may watch that line as a possible support area. If the price breaks clearly below it, some may see that as a warning that the trend is weakening. Trendlines are not exact predictions; different traders may draw them slightly differently, and false breaks can happen, especially in fast-moving crypto markets.
