At the bottom of the menu, click the small ruler icon.

This opens a second scale on the chart.

At the bottom of the new scale, there is a menu for selecting the following:

• N = measures net move up or down from the cursor point on the chart.
• % = measures percentage move up or down from the cursor point on the chart.
• $100 = measures a dollar value move up or down from the cursor point on the chart (based on a $100 investment).

Click the letter next to the 0% value in the Ruler scale.

This opens a menu box. (These settings can also be accessed in the main Scaling menu.)

The zero line can be centered on:

• Yesterday's Close (close price of previous-to-the-last price bar)
• Left of Chart (centers the price on the close of the first visible bar on the current chart history)
• Pointer Date Close (close of the bar for the date at which the pointer is pointed when clicked)
• Manual (from the exact price point where the mouse click occurs)

Click the mouse on the chart to place the blue line at that particular price level. This creates the "zero line" from which the moves up and down will be calculated.

This measures the distance at any given point of the chart from the value represented by the blue zero line.

The move from the blue zero line to the current market price (close) is highlighted by a white box on the scale.

Check or uncheck the small Grid button to add the grid lines for the Ruler to the standard chart grid lines already in place.

Right click on the chart and choose Edit Chart Properties to open the Edit window.

Place a check mark next to Show Ruler to open the Ruler Scale on the chart. Settings for the scale are now available in the menu.
