Bahadır Uzel,

You can create and use Custom WaveTrendOscillator like this

class WaveTrendOscillator(PythonIndicator):
    def __init__(self, n1, n2, n3):
        self.Time = datetime.min
        self.Value = 0

        self.esa = ExponentialMovingAverage(n1) 
        self.d = ExponentialMovingAverage(n1)
        self.tci = ExponentialMovingAverage(n2)
        self.wt2 = SimpleMovingAverage(n3)
        
        self.Period = (n1 + n1 + n2 + n3)*5

    def Update(self, input):
        self.Time = input.EndTime
        self.Value = 0
        ap = (input.High + input.Low + input.Close) / 3
        if not self.esa.Update(input.Time, ap):
            return False

        if not self.d.Update(input.Time, abs(ap - self.esa.Current.Value)) or self.d.Current.Value == 0:
            return False
        ci = (ap - self.esa.Current.Value) / (0.015 * self.d.Current.Value)

        if not self.tci.Update(input.Time, ci):
            return False

        if not self.wt2.Update(input.Time, self.tci.Current.Value):
            return False

        self.Value = self.wt2.Current.Value

        return True

If you are satisfied with my answer, please accept it and don't forget to like it.

BTW. Did you have a chance to try what I recommended to you?

thanks, Louis Szeto

Hi Vladimir,

Thanks your answer and code.
