Hi Joseph,
   
  Try the following lines and plot statement in a 
  new formula editor:
   
  Barcolor = IIF(C>Ref(C,-1) , colorGreen, colorRed 
  );
  Plot(C, "Close ", Barcolor , styleBar |styleThick ) 
  ;
   
  This colors the bars based on the relation of the 
  close to the prior close.  If you want the bars to depict 
  the relation from open to close or to show volume changes, you can edit 
  the Barcolor statement. You might also want to add a Title statement and some 
  other things (like setting the chart options).

    Hi All --
    
    How do I make the up days of a bar chart green and down days red?
    
    Thanks
