darvas metastock formula from b2
just import it into a new indicator formula box



LL:=If(L=LLV(L,5),L,If(Ref(L,-1)=LLV(L,5),Ref(L,-1),If(Ref(L,-2)=LLV(L,5),Ref(L,-2),If(Ref(L,-3)=LLV(L,5),Ref(L,-3),If(Ref(L,-4)=LLV(L,5),Ref(L,-4),0)))));
NH:=ValueWhen(1,H>Ref(HHV(H,5),-1),H);
Set1:=HHV(H,3)Val1:=ValueWhen(1,BarsSince(H>Ref(HHV(H,5),-1))=3 AND Set1=true,NH);
Val2:=ValueWhen(1,BarsSince(H>Ref(HHV(H,5),-1))=3 AND Set1=true,LL);
TB:=Val1; BB:=Val2; TB;BB

B2 got this some time ago from stockcentral and thinks it was from TechA..

some interest in Darvas at HC

B2 I hope you dont mind me passing your formula on.

I believe guppy had some other quite similar Box formula and systems based on range breakouts.
A jack in the box system rings a bell ?

must swat it up.
