How to create an indicator

[heguilar]

Good morning.
I need a very simple indicator, that I mark the open price of 2 candles backwards. I tried to do it, but I still do not handle this language very well.

Hello heguilar,
Thanks for your post.

What do you mean by "backwards"? It seems like you are you trying to store the open values for two candles and then swap those values. Is this correct?

Please show me the code you have written so far so that I have a better idea of what you are trying to accomplish.

I look forward to your reply.

Good morning. I need an indicator that I paint the open [1]. IIt's very simple, but I do not know how it's done.

Hello heguilar,
Thanks for your note.

You could plot Close[1] with your indicator by doing something similar to the following snippet.

protected override void OnStateChange()
{
	if (State == State.SetDefaults)
	{
		AddPlot(Brushes.Orange, "MyPlot");
	}
}

protected override void OnBarUpdate()
{
	if (CurrentBar<1)
		return;
	Value[0] = Open[1];
}

I am including the relevant help guide documentation on how to accomplish this below, for your convenience.
