Explore ^NDX for the n=1 last bar with
H2=HHV(IIf(H!=H1,H,0),100);
H3=HHV(IIf(H!=H1 AND H!=H2,H,0),100);
H4=HHV(IIf(H!=H1 AND H!=H2 AND H!=H3,H,0),100);
H5=HHV(IIf(H!=H1 AND H!=H2 AND H!=H3 AND H!=H4,H,0),100);
Filter=1;
AddColumn(H1,"h1");
AddColumn(H2,"h2");
AddColumn(H3,"h3");
AddColumn(H4,"h4");
AddColumn(H5,"h5");
The result is the top5 H .
If we take the 100 results of the
Filter=1;
AddColumn(Stochd(),"STOCHD");
exploration of n=1 last bar of the 100 N100 stocks and put them as
the last 100 values of H of a certain stock, we could do it.
