You might like to view the original version of the indicator if you don't know about OTT yet:
He tried to solve the fake signals of Oscillator by adopting OTT on the indicator.
He advised users to set the smoothing parameters to 500 and 200 on his latest video about SOTT.
He personally uses 1 min charts on stock market so the parameters of the indicator might have to be optimized for other time frames nad markets.
He exaggerated the to 1000's to have better signals of percent values of OTT .
Also hes used in both calculations of OTT and smoothing.
Hope you'll enjoy the SOTT in your profitable trades.
