Oscillator: Which follows Normal Distribution?

When doing machine learning using oscillators, it would be better if the oscillators were normally distributed.

So I analyzed the distribution of oscillators.

The value of the oscillator was divided into 50 groups each from 0 to 100.
ex) if rsi value is 45.43 -> group_44, 58.23 -> group_58

Ocscillators : RSI, Stoch, MFI, WT, RVI, etc....

Caution: The normal distribution was verified through an empirical formula.
