What is in it

Each row is one bookmaker's price series for one runner: the first price observed once the race entered the 60-minute capture window, the last price observed before the jump, when each was seen, and how many price changes were captured in between. Every row's last observation was within 300 seconds of the advertised start, so the close is a closing price, not a last-seen price from earlier in the day.

The rows are what GET /v1/racing/closing-lines returns with its default filters for this month, these bookmakers and country=AU. A bookmaker is included in a release when at least 75% of its series that month were last observed within 300 seconds of the jump.

Code	Races	Rows

Greyhound	3,850	129,802
Harness	1,141	48,780

Two figures from this release

Best or equal-best closing win price, on runners priced by at least three of the bookmakers in the release:

Bookmaker	Share of its priced runners
PointsBet	50%
BetRight	45%
TAB	40%
TABtouch	28%
Ladbrokes	19%

Median market percentage at the close: the sum of 1/price across a full field, where 100% would mean no margin.

Bookmaker	Thoroughbred	Greyhound	Harness
TAB	121.9%	123.3%	126.1%
Ladbrokes	121.4%	126.1%	126.8%
PointsBet	119.6%	122.9%	124.9%
BetRight	119.9%	123.1%	123.7%
TABtouch	120.4%	123.1%	125.2%

Both are computed from the release files by the script that builds them, and are descriptive only.

Columns

Column	Type	Meaning
race_id	string	PuntersEdge race identifier. The same id the API returns on /v1/racing/results and /v1/racing/closing-lines.
start_time	datetime	Advertised start time of the race, UTC.
meeting_date_aet	date	Racing day the meeting belongs to, in Australian Eastern time.
venue	string	Venue name.
race_number	integer	Race number at the meeting.
category	string	horse (thoroughbred), harness or greyhound.
country	string	AU for every row in this sample.
runner_key	string	Runner name folded to lowercase letters and digits. Joins one runner's rows across bookmakers within a race.
runner_name	string	Runner name as published.
runner_number	integer	Saddlecloth or rug number.
bookmaker_key	string	Bookmaker the prices were observed at: tab, ladbrokes_au, pointsbetau, betright or tabtouch, depending on the release.
open_win_price	number	First fixed win price observed in the series, in decimal odds.
open_secs_to_jump	integer	Seconds before the advertised start at which the first price was observed.
open_is_baseline	boolean	True when the series began when the race entered the 60-minute capture window. False when the bookmaker's market appeared later, so the first price is not a market open.
close_win_price	number	Last fixed win price observed before the jump, in decimal odds. Every row in this sample was last observed within 300 seconds of the advertised start.
close_secs_to_jump	integer	Seconds before the advertised start at which the last price was observed.
points_observed	integer	Number of price observations captured in the series.
finish_position	integer	Official finishing position where one was published. NULL does not mean the runner lost: harness results name the placegetters only, and before 14 September 2026 thoroughbred and greyhound results stored positions 1 to 4 only.
result_status	string	final, interim or abandoned; NULL when no result is held for the race.
venue_id	string	Stable PuntersEdge venue identifier.
horse_ref	string	Thoroughbred identity across meetings: pe: followed by the registered name folded to letters and digits. NULL on greyhound and harness rows.
open_place_price	number	Place price at the first observation. Captured from 29 September 2026, NULL before then and at bookmakers that price win only.
close_place_price	number	Place price at the last observation. Same coverage as open_place_price.
consensus_close_prob	number	The market's margin-free probability for the runner at the close: each included bookmaker's implied probabilities (1 / price) raised to the exponent that makes them sum to one (the power method), the median across bookmakers, the field scaled to one. Power replaced the simple divide-by-the-sum on 6 October 2026 because it is calibrated across the price range; every archived row carries the one method. Computed over every Australian bookmaker in the archive (14), not only the five in this release. It describes what the market implied, not the outcome.
consensus_close_price	number	1 / consensus_close_prob.
books_in_consensus_close	integer	Bookmakers whose closing line entered consensus_close_prob.
consensus_open_price	number	The same price from series that began at the 60-minute baseline. NULL where fewer than two complete-field bookmakers did.
books_in_consensus_open	integer	Bookmakers behind consensus_open_price.

Before you model on it

finish_position empty does not mean the runner lost. Harness results name the placegetters only; thoroughbred and greyhound results position every finisher from 14 September 2026, and before that date positions 1 to 4. Use result_status to tell a race with no result from a runner without a position.
open_is_baseline false means the bookmaker's market appeared after the race entered the capture window, so the first price is not that market's opening price.
Place prices start on 29 September 2026. Prices are decimal odds as displayed, margin included. Times are UTC; meeting_date_aet is the racing day in Australian Eastern time.
Coverage and freshness of the archive these files come from are measured on the data quality page.
