Applying Dual Scaling to a Chart
You can display two y-axis scales in the chart. This feature is especially useful when overlaying an indicator on price data and the indicator uses a different scaling than the symbol. For example, if you overlay the Stochastic Slow indicator on top of Microsoft, you could use the left side scaling to display the Stochastic Slow's values and the right side scaling to display Microsoft's price.
Activate a Chart Analysis window containing a plotted symbol. Access using the Studies > Add Study menu sequence to add an indicator that has its own scale. The Add Studies dialog is displayed.
- Select the desired study from the types of study tabs you want to apply to the chart. Indicators with their own scale should appear in a separate sub-graph beneath the symbol data.
- Click and drag the indicator from its sub-graph to the symbol sub-graph (select a point on the indicator using the mouse, hold down the left mouse button, and drag the indicator while selected).
- To customize that axis scaling, access the Customize Study - Scaling dialog and click the Scaling tab.
- From the Axis section, select the desired axis type to use for the indicator scale from the drop-down list.
Click OK to apply changes or Cancel to exit without changes.
The left and right vertical axes will appear in the chart with the symbol's price data on the one side and the indicator scale on the other side.
