Line objects are ultimate technical analysis tools used for identifying the trends, support and resistance levels, chart patterns etc. The Objects menu offers three types of lines that you can plot in the chart:
| • | Trendline – can be drawn in any direction; it requires two points to be plotted |
| • | Vertical Line – requires only one point to be plotted in the chart |
| • | Horizontal Line – requires only one point to be plotted in the chart. |
When you select any of these options, the cursor will turn into a hand: 
, so you can choose the start point of your line. In order to plot a trendline, drag the cursor to the end point of your line, and release it.
When you left-click on the line, it will become highlighted, and you will be able to drag it over the chart – the cursor will turn into a hand:

If you hover cursor over a dot on either end of the trendline, it will turn into a crosshair allowing you to drag the dot over the chart:
Right-clicking on the line opens the standard context menu for manually plotted objects:
To delete the line left-click on it once and choose the Remove Selected Objects option on the chart toolbar.
