pk = H>Ref(HHV,-1) AND Ref(HHV,nbar)<=H;

what does this calculate?

tr=L<Ref(LLV,-1) AND Ref(LLV,nbar)>=L;

what does this calculate?
what does pk,tr calculate ?
whats fc?tell in detail pls.

Hellow,

As nbar values changes, so are the HH,LL… are changing.

I trade on hourly chart, what is correct/optimum value of Nbar setting.

Thanks

Thanx i know what is said..i want to know in detail..i want to make sure what i think is right.
if high-greater then HHV for nbars referencing previous HHV then take high as HH and if High greater then or equal to HHV reffering “n” bar and viceversa.
is it so?
why do u have to take fractals as 1,2,3.what if we take only one fractal?
