Description
The basic trendline is the simplest drawing used by technical analysts. It is used for revealing trends and their acceleration, applying the fan principle, analyzing relative steepness, and many other purposes. For your convenience, we added a label to the trendline, which displays its principal parameters: the length of the trendline (as expressed in both number of bars and time units such as days, hours, minutes, depending on the timeframe you are using), the price change correspondent to the difference between its start and end points (expressed in both dollars and percentage), and its slope. Bullish trendlines have positive values of the price change and the slope, while bearish trendlines show the negative ones.
Although choosing a correct trendline is a problem sometimes, adding it to chart is quite simple. Choose Trendline from the Active Tool menu. Specify two points that will define the slope of the trendline. The trendline will appear on chart.
