How to Use the Locked Log Scale (vs SP500)

This scaling mode allows you to make a direct visual comparison of the volatility of the stock you are viewing with the volatility of the broader market as represented in SP-500.

1. Locked Log Scale

Use the radial button to select Locked Log (Logarithmic). Locking the log chart means that whatever value you choose to Lock your chart scale to, that value will be for every chart you view in this mode.

Relative to SP-500: This scale method allows you to see the volatility (movement) of your stock directly compared to the volatility of the SP-500. The x factor (slider) is used to determine the comparison. (For example: choose 100x for the S&P plot to fill 100% of the window; 1x means the SP-500 takes up 1% of the window.) Move the slider back and forth to expand/contract the window. If a stock is very volatile compared to the SP-500, some or much of its price history can actually go off the top/bottom of the chart (see below) at 100x. As you move from chart to chart, you get a much better picture of how the volatility of the stock you are viewing compares to the broader market (SP-500).

  • Check or uncheck SP-500 to show/hide the plot of the SP-500.

The logarithmic scale in this mode shows an equal percentage difference between the chart units. Price is measured in equal percentages which are automatically set by the number of gridlines chosen. While the percentages remain the same between gridlines, the gridlines are not evenly spaced. The standard log chart will have rounded numbers. The x factor is shown in red at the bottom of the scale.

Log %Grid display mode. (Place a checkmark in the tick box to choose %Grid). Increase/decrease the number of gridlines and the percentage adjusts itself. Zooming to more or less price history or changing the time frame of the chart will affect the % shown. The %Grid log chart will not have rounded numbers. The percent difference between gridlines and the x factor are shown in red at the bottom of the scale.

Hover the mouse over the Locked Log SP-500 scale to increase/decrese the number of gridlines.

In Locked Log mode, the keyboard combination shortcut Alt + Scrollwheel will tighten/loosen the chart axis.
