Swing indicator questions

[poseidon_sthlm]

Hi!
I have two questions to the code of the standard NT Swing indicator.

1) In what situations will the code in the "else branch" be executed, that is when (saveCurrentBar == CurrentBar) ? Why does it exist? The only situation I have figured out is when you loop through the indicator on historical bars, but I still don't understand the reason for the code in this situation, since the historical output values are stored in DataSeries.

        protected override void OnBarUpdate()
        {
            if (saveCurrentBar != CurrentBar)
            {
                /.../
                
                saveCurrentBar = CurrentBar;
            }
            [COLOR=Red]else
            {
                /.../
            }[/COLOR]
        }

2) Why do you have to use "Update()" in the properties section although you use the IDataSeries Class?

public DataSeries SwingLow
        {
            get 
            { 
               [COLOR=Red] Update();[/COLOR]
                return swingLowSeries; 
            }
        }

Hello poseidon_sthlm,

I will have someone reply to you on Monday. Thank you for your patience.

poseidon, I believe the else branch is for situations where CalculateOnBarClose = false and the indicator needs to be re-drawn.

Along those lines, the Update() is there so if the indicator is called, it will be updated (re-drawn) before the results are returned.

Thanks for the reply. Although the option exists, it would be unusual to use the Swing indicator with COBC == false, in my opinion. But the code then makes sense.
