Fractals – adjustable period and prices

One of the “classics” but with a twist – unlike the built-in fractals indicator, this one allows you to :

• adjust the fractals period (the built-in fractal indicator is using period 5)
• chose prices for high and low (might be useful in some cases – in extreme whipsaw market conditions, for example)

The way how fractals are calculated does not prevent having fractal up and fractal down at the same bar and that is the correct way how it should be calculated. Limiting it to just one fractal per bar is introducing a bias that has no mathematical cause.
