• There's inconsistency in the way you display the dollar sign: lining and superscript
• Same thing with using a comma with 4-digit numbers: sometimes you do, sometimes you don't
• Sometimes you insert a space after the plus sign, and sometimes you don't
• Pretty sure that dark gray text on a black background doesn't pass a color contrast test
• Add some tracking to your all-case text
• Icons are inconsistent: not only in their visual height, but also with the widths of their borders
• Spacing of numbers is inconsitent as well
• Would recommend a different typeface. A typeface in which the numbers shine much better. Search for "stock app" on dribbble and you'll find some examples
