What do depth, spread and turnover mean?

Depth is the units listed now. Spread is the gap between the 25th and 75th percentile of the listings at the latest scan, as a share of the median: a wide spread means the price you get depends on timing. Turnover is how much of the shelf changes a day, so a high turnover means the item sells.

What is a supply shock on the auction house?

The newest day of scans shows an item listed in a quantity two standard deviations away from its previous 30 days. Flooded means far more than usual is listed, and the price tends to sag; drained means the shelf emptied, and the price tends to climb.

Depth is units listed now. Spread is the gap between the 25th and 75th percentile of the book at the most recent scan, as a share of that scan's median. Turnover is how much of the shelf changes per day. A shock is the newest day's quantity sitting two standard deviations from the 30 days before it.
