Running code only once

[NinjaTrader_ChelseaB]

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;
}

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.
