To be more exact, the top5 of the last 100 H is
H1=LastValue(HHV(H,100));
H2=LastValue(HHV(IIf(H<H1,H,0),100));
H3=LastValue(HHV(IIf(H<H1 AND H<H2,H,0),100));
H4=LastValue(HHV(IIf(H<H1 AND H<H2 AND H<H3,H,0),100));
H5=LastValue(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");
