access the values of Indicators.Fractals

Hi xabbu,

The values are stored in UpFractal and DownFractal data series

            var fractals = Indicators.Fractals(10);
            Print(fractals.DownFractal.LastValue);
            Print(fractals.UpFractal.LastValue);

The values are saved at the relevant index of the data series. If there is no value, then the value will be NaN. Therefore the last fractal is the one with a value at the highest index.

Thank you, Panagiotis!

I have never before worked with NaN and it seems I cant get it to work:

if (double.IsNaN(_fractals.UpFractal.LastValue))
                {
                    Print("Down: " + _fractals.DownFractal.LastValue);
                }

                if (double.IsNaN(_fractals.DownFractal.LastValue))
                {
                    Print("Down: " + _fractals.DownFractal.LastValue);
                }

Can you point me in the right direction, please...?

Kindest regards,

Hi xabbu,

What is the code you posted supposed to do?

Panagiotis, thank you for taking care!

The code does nothing and was only meent to give me access and an understanding for the function.

What I want to do:

if the last fractal was above (signaling a down trend) I want to take only short trades.

if it was below only long trades.

I would like to use fractals as a kind of filter to prevent unwanted trade direction like here in this picture:

the fractal at the left should prevent me from taking the circeled long trade...

Hi xabbu,

Here is an example

            var fractals = Indicators.Fractals(10);
            int lastUpFractalIndex = 1;
            int lastDownFractalIndex = 1;
            
            while (double.IsNaN(fractals.UpFractal.Last(lastUpFractalIndex)))
                lastUpFractalIndex++;
            while (double.IsNaN(fractals.DownFractal.Last(lastDownFractalIndex)))
                lastDownFractalIndex++;

            if (lastUpFractalIndex < lastDownFractalIndex)
                Print("Last Fractal  was Up");
            if (lastUpFractalIndex > lastDownFractalIndex)
                Print("Last Fractal was Down");
