I also found the correct way to get the last breakout fractal:

var FracalUP = FractalHigh(series(priceHigh()),5);
var FractalDW = FractalLow(series(priceLow()),5);

To access fractals back history:

vars FractalUP = series(FractalHigh(series(priceHigh()),5));
vars FractalDW = series(FractalLow(series(priceLow()),5));

and then FractalUP[n] and FractalDW[n]
