Drawing a Basic Trend Line
To plot a trend line onto the chart, first click once to set the
starting point and then a black line will appear. Drag the line
to the desired point and click once again to set the destination
point. A red line will then appear between the starting and destination
points, similar to the example below. A number will appear as well
indicating the destination point’s price on the price scale. Only
the price of the last trend line drawn will be shown.
Drawing Parallel Trend Lines
The fourth button on the action toolbar yields the parallel trend
line function. It can only be used if a trend line already exists
on the chart. A black line, parallel to the last trend line drawn
and of equal length, like the example below, will appear when the
function is selected. It can be plotted anywhere on the chart. To
plot the parallel line, simply click on the chart once at whichever
position on the chart the user chooses. Once plotted, the line will
turn red and the end price of the new line will be shown.
Erasing Trend Lines
Use the toolbar buttons to erase trend lines. The first button
(left) will erase the last trend line drawn, and the second button
(right) will erase all trend lines drawn
