Developed by Emily Karobein, the Karobein oscillator is an oscillator that aim to rescale smoothed values with more reactivity in a range of (0,1)

The scaling method is similar to the one used in a

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.

where

Then we rescale the results.

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,

20 trades have been mades since the 29 oct we made 341 pips with eur/usd, of course this backtest was made during good trends period,

this result is not representative of how the strategy work with other conditions/markets.

*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.
