In trading, a trend line is a straight line that is drawn on a price chart to represent the general direction of price movement over a certain period of time. Trend lines are used to help identify trends in the market, and can be used to help traders make decisions about when to buy or sell a particular asset.
A trend line is drawn by connecting two or more price points on a chart, typically by connecting a series of higher lows in an uptrend, or a series of lower highs in a downtrend. Once a trend line has been drawn, it can be used to help identify potential support or resistance levels for the price of the asset.

In an uptrend, the trend line acts as a support level, with prices tending to bounce off the trend line as they rise. In a downtrend, the trend line acts as a resistance level, with prices tending to bounce off the trend line as they fall. If the price breaks through the trend line, it can signal a potential trend reversal.
Trend lines can be drawn on different time frames, such as hourly, daily, weekly, or monthly charts, depending on the trader's trading style and time horizon. They can also be combined with other technical analysis tools, such as moving averages, to help confirm potential trends or reversals in the market.
It is important to note that trend lines are subjective and can vary depending on the trader's interpretation of the market. It is therefore important for traders to have a clear trading plan and to use trend lines in conjunction with other technical analysis tools and fundamental analysis to help make informed trading decisions.
