Hello Dimitri,

Thank you for your post.

You would want to use the Lower and Upper bands for the Darvas indicator.

if(Close[0] < Darvas().Lower[0])
{
     //do something
}

Let me know if I can be of further assistance.

Thank you for your answer Cal,
I tried this but it doesn't show any signal

What signal are you looking for exactly?

Can you share the code and what you are wanting to it to do?

// Condition set 1
if (Close[0] < Darvas().Lower[0])
{
DrawArrowDown("Doji", 0,High[0]+TickSize, Color.Blue);
}

Here is my code, There is no arrow when the price is under the boxbottom.
I tried the strategy on on the chart attached but it doesn't show any results, it should draw an arrow at every bars closing under the boxbottom.

Dimitri,

Your code will draw an arrow at the most recent occurrence of the condition but will only draw 1 arrow.
If you want to have your code draw an arrow at each occurrence you will need to use this for your script -

DrawArrowDown('Doji' + CurrentBar, 0,High[0]+TickSize, Color.Blue);

Thanks for your quick respond Cal,
i changed my line of code but there is no occurence at any moment on the chart, i think the problem comes frome this line : // Condition set 1
if (Close[0] < Darvas().Lower[0])
Thanks in advance, Dimitri.

Do have a CurrentBar check in place, at the beginning of your OnBarUpdate()?

if(CurrentBar < 1)
return;

I added it but it doesn't change anything, my code looks like this right now :
/// <summary>
/// This method is used to configure the strategy and is called once before any strategy method is called.
/// </summary>
protected override void Initialize()
{


CalculateOnBarClose = true;
}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()

{
if(CurrentBar < 1)
return;
// Condition set 1

if (Close[0] < Darvas().Lower[0])
{
DrawArrowDown("My down arrow" + CurrentBar, false, 0, 0, Color.Red);
}
}

Thanks in advance, Dimitri.

That is because you are setting the Y value to a hard 0. Which means the arrow will plot it at the 0 line.
DrawArrowDown("My down arrow" + CurrentBar, false, 0, 0, Color.Red);

You will want to use a price point to plot the arrow like below -
DrawArrowDown("My down arrow" + CurrentBar, false, 0, High[0] + 1 * TickSize, Color.Red);
