Re: Exploration with Directional Movement Index

[Dave Nadeau <dave.nadeau@xxxxxxxx>]

Although the names in the quicklist drop down box are + or - DI, you will
need to use PDI or MDI in your formulas.  That seems to be causing your
problem.  PDI=Plus Directional Movement Index and MDI=Minus Directional
Movement Index

So use

DIRECT:=PDI(14)>MDI(14);
DIRECT AND Ref(DIRECT,-1)=0;
