The widget is minimalistic and tap to refresh is excellent (especially the visual indicator with the 3 dots)! What would make the widget perfect though is to have a 1x1 size widget  especially because it seems that the existing price indicator can fit just fine in the 1x1 space (without icon or decimals)  so it seems reasonable and I can't really afford for the widget to take space for 2 icons. I actually recommend 1x1 to be the only one because from there everybody can resize to their liking (to bigger).
