Trendline: What It Is, How To Use It in Investing, With Examples
What Is a Trendline?
Trendlines are lines that traders draw on charts to connect prices or show data’s best fit. The resulting line gives the trader an idea of the direction of an investment’s value.
A trendline is drawn over pivot highs or under pivot lows to show the direction of price. Trendlines represent support and resistance in any time frame. They show direction and speed of price and describe patterns during periods of price contraction.
Key Takeaways:
– Trendlines indicate the best fit of data.
– A single trendline can give a clearer picture of the trend.
– Trendlines can be applied to create a channel.
– Trendline creation varies among traders.
What Do Trendlines Tell You?
The trendline is an important tool for technical analysts. Instead of looking at fundamentals, technical analysts look for trends in price action. A trendline helps determine the current direction in market prices. Identifying this trend is the first step in making a good trade.
To create a trendline, an analyst needs at least two points on a price chart. Some analysts use different time frames, such as one minute or five minutes. Others look at daily or weekly charts. Trendlines can be used to help identify trends regardless of the time period or interval used.
For example, if company A’s price goes from $35 to $40 in two days and $45 in three days, the trendline has a positive slope, indicating the analyst should buy in the direction of the trend. If company A’s price goes from $35 to $25, however, the trendline has a negative slope, indicating the analyst should sell in the direction of the trend.
Example Using a Trendline
Trendlines are relatively easy to use. A trader charts the price data normally, using open, close, high, and low. Below is data for the Russell 2000 in a candlestick chart with the trendline applied to three session lows over a two-month period.
The trendline shows the uptrend in the Russell 2000 and can be thought of as support when entering a position. A trader may choose to enter a long position near the trendline and then extend it into the future. If the price breaches the trendline on the downside, the trader can use that as a signal to close the position. This allows the trader to exit when the trend weakens.
Trendlines are a product of the time period. In the example above, a trader doesn’t need to redraw the trendline often. On a minute time scale, however, trendlines may need to be readjusted frequently.
The Difference Between Trendlines and Channels
More than one trendline can be applied to a chart. Traders use a trendline connecting highs as well as another connecting lows to create channels. A channel adds support and resistance for the analyzed time period. Traders look for a spike or breakout to take the price action out of the channel, using it as an exit or entry point.
Limitations of a Trendline
Trendlines need to be readjusted as more price data comes in. Additionally, traders may choose different data points to connect. Trendlines on smaller timeframes can be volume sensitive and easily broken as volume picks up.
