Metastock:

d:=If(C>Ref(H,-1), Min(L,Ref(L,-3)) , If(C<Ref(L,-1), Max((H,Ref(H,-3)) ,PREV));


,and what I do in Multicharts:

 

Code

vars: war1(0); vars: war2(0); war1=minlist(L,L[3]); war2=maxlist(H,H[3]); if C>H[1] then begin Plot1( war1, "A" ) ; end else begin if C<L[1] then begin plot1(war2,"A"); end else (previous?)

THX

Something like this:

 

Code

Value.Set(CurrentBar == 0 ? Median[0] : Close[0] < Low[1] ? MAX(High, 3)[0] : Close[0] > High[1] ? MIN(Low, 3)[0] : Value[1]);

But, it's not syntax of Multicharts, right?

Oh, sorry, haven't noticed this is about MultiCharts. - Thought it's Ninja question
