How to read this chart

The green line is the TruthIndex™, the chance of this outcome. Only one venue lists it, so the figure comes from that venue alone. The thinner line is that venue's own daily price.

The pale bands behind the lines are the rating zones (Toss-up, Lean, Likely and Safe), so you can see when the race moved from one rating to another. Move along the chart, or use the arrow keys, to read the values for each day.
