That's a well created chart, with a blue line added up. I wonder, with all due respect, if that same chartist didn't have the exact same chart with a giant red line added when things were looking bad a week or so ago. My point being, the wave thing, like most carts are all seen differently, but the chart doesn't lie, as numbers don't lie, but an individual adding in lines up or down is purely subjunctive, and as such open to change , as their opinion changes.
