Hi Joseph,

Works for me when I do just what you said you did. What can I say? I don't think it would be a background color same-same issue as my code uses two different colors.

OK let's see if we can figure this out. Though I don't think it necessary (because the code should save to the Custom folder automatically when you apply or insert the indicator), I always do a "save as" to a different folder under Formulas (in this case I would save to a folder named My Price Charts) with an individual name (this might be Colored Bars.afl). If your code is automatically saved it is given a nondescript name of Indicator X, where X is a number which increments with each new code saved. Check your custom folder and see if you can identify the code you tried to insert. If it isn't there, then you probably didn't do an apply to the test code. If it is there, you can now try to insert it (select the code and right click to get a menu of options).

Another habit I suggest that is useful is to click the little AFL checkmark icon before saving or applying code. This will help spot many errors that might be in your code and need fixing before you try to use it. And the reason I save to different folders is both for organization and to prevent code from being overwritten when doing upgrades.

Peace and Justice --- Patrick

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
