How to run a study only once and/or to remove a study after calculcation?

[datapool]

I want the study just to execute once and then remove the study after execution? Is there a java call to remove a study from the chart? Or how do I ensure the study is only run once on the chart?

I have tried this and it looks to be impossible. Calling this.Destroy() from a Study will throw a null pointer in the application. There is no java call to remove a study from a chart. Alternatively, you can use a simple static counter object to ensure that calculations are only done once.
