Support and Resistance - Technical Analysis

Markets have a tendency to move in troughs and peaks or, more appropriately, "Support and Resistance."


These Troughs are called support, indicating that support is level. This shows that buying interest is strong enough to overcome selling pressure. A decrease in price is reversed and prices rise once again. Typically, a support level is identified by a previous set of lows.




Resistance is essentially the opposite of support. Resistance is defined as a horizontal ceiling where the pressure to sell is greater than the pressure to buy. An increase in price is reversed and prices revert downward. Typically, support can be located on a chart by a previous set of highs.


Resizing the Line

Select the line drawing by clicking on it. The line is selected when boxes appear at the ends of the line. Click on one of the boxes and drag it to the desired length. Release the mouse button to place the end point of the line.

Moving the Line

Select the line drawing by clicking on it. Click on the line, not an end box, and drag the line to the new location. Release the mouse button to place.

Deleting the Line

Select the line drawing by clicking on it. Press the Del (Delete) key on your keyboard. You can also right-click the line drawing and select “Delete” from the drop-down menu.

Keyboard Shortcut

Hold down Control (CTRL) on your keyboard while drawing the line tool to create a straight/flat line.
