Running code only once

[several]

Hello, I created a basic indicator which draws fixed text on the chart. (Attached)

The text is static and simply pulls the Instrument Name and allows the user to adjust some spacing/colors etc..

My question is. Obviously I don't want the code to continually run on the close of every bar. But which is the best way to make it only run once.

I have used an IF statement to contain the entire code and a simple variable to make sure it just runs once but is that the best way to do it?

            if (
                MyVar == 0
                )
            {
​                // My Indicator code

               MyVar =1;
            }

I also tried to put the entire code inside State.Configured but the code contains a FOR loop and this didn't work inside there.

Hello several,

For actions you want to trigger only once that doesn't reference bar data can be done in OnStateChange() when State is State.DataLoaded.

Running a loop within State.DataLoaded is fine to do.

If the code references bar data, this should be done in OnBarUpdate(). You can use a bool to trigger the action once.

private bool actionTriggered;

In OnBarUpdate():

if (actionTriggered == false)
{
// trigger the actions
actionTriggered = true;
}
