Scaling

Brief

This section describes all possible ways of scaling a chart.

Details

Scaling allows you to scale a chart horizontally and vertically to change the number of periods and the price range displayed on the chart.

Horizontal Scaling

Horizontal scaling allows changing the number of periods displayed on the chart.

To scale a chart horizontally:

1. Point to the horizontal scale.
2. Scale the chart:

• To see more periods, drag the pointer to the left.
• To see less periods, drag the pointer to the right.

Note: The minimum number of periods you can see on the chart is five. The maximum number equals the number of periods in the chart.

You can change the horizontal scale by means of zooming. To see less periods, you should zoom in a chart. To see more periods, you should zoom out a chart.

To zoom in a chart, do one of the following:

• On the toolbar, click Zoom In.
• On the Chart menu, point to Zoom, and then click Zoom In.
• Right-click in the horizontal scale, and then click Zoom In.
• Right-click in the chart, point to Zoom on the shortcut menu, and then click Zoom In.
• Rotate the mouse wheel up.
• Press ALT + =.
  
  * In the E*TRADE FX platform, you can also zoom in a chart in the following way:

Vertical Scaling

Vertical scaling allows changing the price range displayed on the chart.

To scale a chart vertically:

1. Point to the vertical scale.
2. Scale the chart:

• To extend the price range, drag the pointer up.
• To reduce the price range, drag the pointer down.

Note: When the vertical autoscaling is enabled (see below), you can extend the price range until a zero price appears on the axis and reduce the price range until all prices become visible.

Vertical Autoscaling

Vertical autoscaling allows scaling the price axis so that when a chart is scrolled, all prices for the displayed periods are visible.

The vertical autoscaling is disabled by default.

To enable/disable the vertical autoscaling, do one of the following:

• On the toolbar, click Autoscale Chart Vertically.
• On the Chart menu, point to Zoom, and then click Autoscale Chart Vertically.
• Right-click in the vertical scale, and then click Autoscale Chart Vertically.
