The trendline is one of the most important yet simple tools available among the drawn objects. It connects two anchor points together on a chart and, if you like, can extend rays to the left and right of those anchor points to indicate support, resistance, and breakthroughs.
To draw a trendline, choose this icon:

As shown in the animation below, you click one anchor point, move the mouse to the second anchor point, and click again. As with all drawn objects, you can right-click on it and change its style, color, and other properties.

You can right-click on any trendline and choose Change Style, which will bring up the dialog box shown below.

The Change Styles box lets you control:
- The color of the trendline;
- The opacity (how much you can see through it);
- The weight (or thickness);
- Whether the pattern is solid, dashed, or dotted;
- What text you want associated with the trendline, if any;
- Whether any text is above or below the line;
- Whether any text is left-, center-, or right-aligned;
- The font size of the text, if there is any;
- Whether the line extends to the left, right, or both;
- Whether your settings should be preserved as the default for all future Trendlines that you will draw
