Order book. Smarkets. Edition of 2026-09-06.

8 of the 125 runners on Sun 6 Sept moved further than usual for their price

We sample the Smarkets order book every fifteen minutes until the off. This is the finished record for the races run on Sun 6 Sept: 125 runners in 13 races, each with the first and the last price we saw before it ran. 8 of them moved further than usual for their price.

Corrected. Reissued on 6 October 2026. A faulty country filter had let runners at meetings outside the UK and Ireland, mostly German and Saudi, into this archive. Any that ran on this day have been removed, and every percentile has been recomputed against a baseline without them.

“Usual” is judged against the 17 days we had collected before this one, and nothing later. A move is compared with what had been measured by the evening before, so the count above does not change as the archive grows.

Prices are the mid of the best back and lay on Smarkets, in decimal odds. A negative move is a price shortening. “Last look” is how long before the off we last saw a two-sided book for that runner. Race times are BST.

Every runner that day

Grouped by race, and within a race from the largest shortening to the largest drift, so that money leaving one runner for another shows at the two ends of the same block.

“One-sided” means the book had no back or no lay at our last look, so there was no spread to quote. It is the state of the book, not missing data.

What “usual” meant that day

The reference each move was judged against: every move we had measured over the 17 days before this one, by the price the runner opened at. The median is near zero in every band. What changes with the price is how far a move normally goes.

Opening price	Moves measured	5th pct	25th	Median	75th	95th pct
1.5 to 3	243	-17.6%	-7.3%	+1.0%	+11.7%	+35.0%
3 to 5	695	-26.5%	-9.4%	+1.4%	+13.9%	+41.5%
5 to 8	1,012	-32.7%	-11.5%	+0.2%	+13.9%	+48.8%
8 to 13	1,138	-35.1%	-13.9%	+0.5%	+16.8%	+55.1%
13 to 20	889	-40.4%	-17.2%	+0.5%	+23.2%	+70.3%
20 to 35	914	-43.4%	-17.9%	+3.6%	+27.1%	+99.2%
35 to 100	992	-58.4%	-29.3%	-7.3%	+18.0%	+67.4%

A runner is counted as outside the usual range when its move sits at or below the 5th percentile, or at or above the 95th, for its band. A runner whose opening price falls in a band with fewer than 100 measured moves is left out of the record rather than judged against too little.
