Each bubble groups sales that sold close together in time and price, sized by how many; hover one for its sales. Solid counts toward fair value, hollow was left out. The line is fair value over time, from sales only, ending at today's. The strip underneath counts sales. Past today, the dashed line is the forecast: where fair value is heading from what sold and how fast it's selling. The shaded fan is how far fair value may move, 4 times in 5; it widens the further out it looks. The forecast never changes fair value.
