Oscillatory time-series forecasting

Question

I was wondering if this mean(160)-reverting/oscillatory time series "SUM" can be considered chaotic & forecastable to some extend short-term?

Are there time-series forecasting methods that give a broader "range" prediction structure rather than "exact/precise" future numbers (e.g, neural network which can be totally off since it is just trying to curve-fit)? Is fuzzy logic method able to give a prediction interval for the immediate next period in a discrete time series?

I would appreciate if anyone can provide some insight to this case study.

Test run quickpick

Test run 1,2,3,4,5,6

Test run (single digit,teens,twenties,twenties,thirties,forties)

1000 times or more each cycle for as many cycles as you want.

Seems like the $returns are indeed better for the third option-middle SUM value or max kurtosis zone.
