6. deff

Great work! thank you

7. empottasch

thanks for the kind remarks and vargasc1 for taking the initiative. Will soon post another interesting indicator.

8. pikachuchary

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.

9. siivaramm

sir error 16 is coming
plz help me

10. kv_maligi

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

11. pikachuchary

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?

12. maheshbanyan

error shown 16.. kindly help me or publish right code

13. ranjitnair

Only two words I will use for this author extraordinary & Superb coding has excellent timing. May God bless him and you too vargasc1 for bringing it here at wisestocktrader.
