Congestion Index is the ratio of the price change to the range change between highest price and the lowest price for a specific period (default 20 bars).
The result is then smoothed to produce the final value.
To apply the Congestion Index to your chart, click the Tools menu, go to the Price Group and select Congestion Index. Left click once on the chart and the tool will be added to its own view below the chart.
Scripting Function: CIDX()

Apply Settings to All: When multiple Congestion Index tools have been applied to a chart, page or workbook, this action can be used to apply the settings of the one selected to other instances of the tool. This is a great time saver if an adjustment is made to the tool - such as line colour - as this allows all the other Congestion Index tools in the chart, page or entire workbook to be updated instantly.
