This is the oscillator strategy that Evan Cabral teaches. He uses three oscillators: DMI Stochastic Extreme, and two Stochastic RSI's.
This script overlays all three in a single display.
リリースノート
Default the DMI Stochastic Extreme to use stochastic length of 3. Default the Stochastic RSI's to 3,3,14,14,close and 3,3,6,6,close. Fill in the Stochastic RSI's. Colors change between the K and D lines. When K is above D it's one color and when below it's another.
