SMA Angle Color

[Luke_Skytrader]

Hello, can anyone tell me what is wrong in my code?
Here I am trying to color an SMA according to its inclination, if the angle is > 10° then it is green and if < 10° it is red otherwise between the two it is neutral with gray.
On my chart the SMA remains green.
Thank you for the help

Code :
namespace NinjaTrader.NinjaScript.Indicators
{
public class SMAAngle : Indicator
{
// Variable declaration
private double inclinaisonMin = 0.5; // Ajustez cette valeur selon votre préférence
private double inclinaisonMax = -0.5; // Ajustez cette valeur selon votre préférence

// Declaration of data series
private Series<double> moyenneMobile;
private double angle; // Nouvelle variable pour stocker l'angle

// Indicator initialization method
protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"SMAAngle";
Calculate = Calculate.OnEachTick;
AddPlot(Brushes.Gray, "Moyenne Mobile");
}
else if (State == State.Configure)
{
AddDataSeries(Data.BarsPeriodType.Day, 1); // Période journalière pour la moyenne mobile
}
else if (State == State.DataLoaded)
{
moyenneMobile = new Series<double>(this);
}
}

// Method called on each new bar
protected override void OnBarUpdate()
{
if (CurrentBars[0] < 110)
return;

//Calculating the 110-period simple moving average
double smaValue = SMA(Closes[0], 110)[0];

// Tilt calculation
double inclinaison = (smaValue - SMA(Closes[0], 110)[1]);

// Calculating angle in degrees
angle = Math.Atan(inclinaison) * (180.0 / Math.PI);

// Assign the moving average value to the data series
moyenneMobile[0] = smaValue;

// Change color depending on angle
if (angle > inclinaisonMin)
{
Values[0][0] = smaValue;
Plots[0].Brush = Brushes.Green; // Couleur haussière
}
else if (angle < inclinaisonMax)
{
Values[0][0] = smaValue;
Plots[0].Brush = Brushes.Red; // Couleur baissière
}
else
{
Values[0][0] = smaValue;
Plots[0].Brush = Brushes.Gray; // Couleur neutre
}
}

region Properties
// Property to adjust the minimum tilt
public double InclinaisonMin
{
get { return inclinaisonMin; }
set { inclinaisonMin = value; }
}

// Property to adjust the maximum tilt
public double InclinaisonMax
{
get { return inclinaisonMax; }
set { inclinaisonMax = value; }
}
#endregion
}
}

Hello Luke_Skytrader,

Thank you for your post and welcome to the NinjaTrader forum community!

I suggest printing the values used in your conditions to change the plot brush, such as angle and inclinaisonMax, to understand what values are being used in the comparisons and which conditions are evaluating to true and which conditions are false. For more details on using prints to debug unexpected behavior:

You could also consider using Slope() in your logic if you'd like:

As mentioned on that page, "Tip: Thinking in degrees, for example a 1 to -1 return range would translate to 45 to -45. To convert you could look into working with this formula - Math.Atan(Slope) * 180 / Math.PI"

Please let us know if we may be of further assistance.
