Pricemarker not visible when use IsFirstTickOfBar and Calculate.OnEachTick

[sidlercom80]

no pricemarker can be seen with this code!

protected override void OnStateChange()
{
   Calculate = Calculate.OnEachTick;
}
protected override void OnBarUpdate()
{
   if (!IsFirstTickOfBar)
       return;

   Line[1] = CurrentBar == 0 ? Input[1] : (Input[1] * constant1) + (constant2 * Line[2]);
}

all ok with this code pricemarker is visible!

protected override void OnStateChange()
{  
   Calculate = Calculate.OnBarClose;
}
protected override void OnBarUpdate()
{
   Line[0] = CurrentBar == 0 ? Input[0] : (Input[0] * constant1) + (constant2 * Line[1]);
}

how can I set the indicator to OnEachTick and work with IsFirstTick so that the pricemarker is also visible?

Let's start with the basics.

Is 'Price marker(s)' checked in the indicator properties?

[sidlercom80]

yes it is checked

Ok, great.

In the OnEachTick version, does Line[0] ever get assigned a value?

Typically, when using OnEachTick, the value in Line[0] would get
recalculated over and over, getting stored back into the same slot,
over and over -- until it gets set in concrete when the bar closes,
because only when a bar closes is a new [0] slot created.

Perhaps the Price Markers (which are associated with Plots) are
only shown for the [0] values ... so if the Plot doesn't have a [0]
value during OnEachTick, the Price Marker is not drawn ...

Try this experiment:
In the OnEachTick version, make sure Line[0] has a value.
Is the Price Marker drawn at the value held by Line[0]?

Hi bltdavid, the tip with the line[0] was good and also well explained by you, thank you very much! good that there are people like you who have enough patience to help people like me a little bit
I didn't realise that the line [1] doesn't work without the line [0], I thought that if the line is visible, the preicmarker must also be visible, but I was wrong.
