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.

▸How this is worked out

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.

Only a day or two of history so far, so turnover and shocks are provisional. The sample column says how many days sit behind each row.

A tight spread with high depth is a market you can move size in. A wide spread with low depth moves against you the moment you buy.

Day of week

Day	Price index	Listings index	Days
Thursday	1.187	0.617	1
Friday	0.813	1.383	1

Each day is indexed against the week around it, item by item, so neither an expensive item nor a market that drifted over the quarter can tilt the table, and the seven are then centred so an average week reads 1.000. Under 1.000 is a cheap day to buy; over 1.000 is a good day to sell. The Days column counts the days behind each figure, not the readings, so read it once there are several weeks there.
