Please help me read this CME chart

Since they are on the left hand side of the column, do the week versus day and month versus day chart mean that most traders are short?

Here is the chart.

No.

Looking at the chart it simply compares volume at time of day for one period with volume at time of day in another period. It's market profile orientated I would guess.

Look in the bottom, there's a link named that points at an example on how to use the chart. How do you access those charts anyway?

Edit: found where.

The URL for the chart is in the pic. So it's volume at a particular price. I've used the info that way before and the market does sometimes react at the price levels with high volume.

Just another piece of the puzzle.

Its actually pretty clear now. Take the leftmost chart on the image you have uploaded. The left white box is the boundary of the last day high/low, and the blue line is the close of the day. The right white box is the same thing but for the current day. So, you see the price action of last day vs current day, as well as the volume.
