Inverse Fisher Fast Z-score

Introduction

The fast z-score is a modification of the classic z-score that allow for smoother and faster results by using two least squares moving averages, however oscillators of this kind can be hard to read and modifying its shape to allow a better interpretation can be an interesting thing to do.

The Indicator

I already talked about the fisher transform , this statistical transform is originally applied to the correlation coefficient , the normal transform allow to get a result similar to a smooth z-score if applied to the correlation coefficient , the inverse transform allow to take the z-score and rescale it in a range of (1,-1), therefore the inverse fisher transform of the fast z-score can rescale it in a range of (1,-1).

inverse = ( exp (k*fz) - 1)/( exp (k*fz) + 1)

Here k will control the squareness of the output, an higher k will return heavy side step shapes while a lower k will preserve the smoothness of the output.

Conclusion

The fisher transform sure is useful to kinda filter visual information, it also allow to draw levels since the rescaling is in a specific range, i encourage you to use it.

Notes

During those almost 2 weeks i was even lazier and sadder than ever before, so i think its no use to leave, i also have papers to publish and i need tv for that.

Thanks for reading !
