Trendlines

Chartists use trendlines to spot trends in security prices. A trendline is a line that is drawn between two or more points on a price chart. An upward-sloping trendline connects two or more low points (troughs) on a price chart. A downward-sloping trendline connects two or more high points (peaks).

When you draw trendlines they will stay on the chart when you change the chart's time frame, helping you to more clearly spot the security's price trend. You can remove the trendlines from the chart by either clicking on the "clear" link next to the Draw Trendlines check box or by entering a new symbol to chart.
