So, which indicator is the best? It's worth looking into.

When the teacher is free, try adding donchian channe to the Stochastic indicator.

The merit is immeasurable!

Alex Grover released the Karobein Oscillator on TradingView which is a code that was originally developed by Emily Karobein and is an oscillator that aims to rescale smoothed values with more reactivity in a range of (0,1)

Calculation

The scaling method is similar to the one used in a Kalman filter for the Kalman gain.

We first average the up/downs x, those calculations are similar to the ones used for calculating the average gain/loss in the relative strength index.

a = ema(src < src ? x : 0,length)
b = ema(src > src ? x : 0,length)

where src is a exponential moving average of length period and x is src/src in the standard calculations, but anything else can be used as long as x > 0.

Then we rescale the results.

c = x/(x + b)
d = 2*(x/(x + c*a)) - 1

How To Use the Karobein Oscillator

It is better to use centerline-cross/breakouts/signal line.

In general when we use something smooth as input in oscillators, breakouts are better than reversals, you can see this with the stochastic and rsi.

So a simple approach could be buying when crossing over 0.8 and selling when crossing under 0.2.

Here is the balance of a strategy using those conditions, length = 50.

Made this version with color change on slope, seems okay but wondering how close it is to Alex Grover's TV version.
