How to connect a script in a chart

To connect a script, such as an indicator, you highlight the chart and click on the Script button in the button bar on the left to open the script database. Alternatively you can right click in the chart and select Work with scripts.

A dialog opens where you can see the scripts that are connected and displayed. It is also possible to enter edit mode to change the script, change the parameters for connection and edit the script, etc.

In the example above, two scripts are attached to the chart. Box #1 is connected to the graphical script Bill Williams Awesome Oscillator. Both the Daily and Intraday resolutions are checked so that the script can draw in both daily and intraday charts.
Show in area determines where the script draws, and in this case we have selected Oscillator area. This means that the oscillator area must be opened in order to be able to see the script curve. Blue pencil is used, and Scaling = Automatic.
The example below shows the results. Among the price bars a parabolic curve is visible (connected to the Box #2).
