How HorseWhale works
HorseWhale is the race-day intelligence layer for UK and Irish racing. Full fields and racecards for every race, a Money Flow figure on every runner built from bookmaker movement, projected race shape, conditions, and a permanent record of what the money did and what happened next.
What HorseWhale watches
HorseWhale reads advertised prices at 25+ bookmakers on every runner in UK and Irish racing, and records qualifying multi-bookmaker price cuts. A displayed price can change for different reasons. HorseWhale records the observable movement; it does not claim to know who placed bets, why a price moved or how much was wagered.
When HorseWhale records an alert
A single bookmaker changing a displayed price can be ordinary repricing. HorseWhale records an alert only when a price cut meets its published multi-bookmaker and probability-movement detection rules. The detection rules are fixed at the time of the alert and the record is kept after the race.
What an alert record contains
A public alert record holds the horse, race, observed move, alert timing, qualifying bookmaker movement and any earlier price still available where recorded. It also includes factual context where the horse’s stored history supports it, plus the later result and SP/BSP grading where available.
What happens after the race
HorseWhale keeps each recorded alert on a public record and grades it against official Starting Price and Betfair Starting Price where that data is available. A recorded price cut is not a prediction of the race result: a horse can have a recorded move and still lose.
What builds over time
Every horse has a permanent HorseWhale page with its multi-year money history. Those pages retain the horse’s recorded alerts and link to the underlying public alert records.
What HorseWhale is not
HorseWhale records market signals and historical evidence. It does not provide tips or race predictions; it does not place bets, connect to bookmaker accounts, show individual bet data or replace an odds-comparison service, racing form database or betting exchange.
Common questions
Why can bookmaker prices change?
Bookmaker prices can change as markets react to public information, displayed demand, risk management, related-market movement and ordinary repricing. A visible price change does not reveal the exact cause.
What makes a HorseWhale alert different from one bookmaker changing price?
HorseWhale records qualifying multi-bookmaker price cuts that meet its published detection rules. One displayed bookmaker change can be an isolated adjustment; a qualifying recorded cut is an observed pattern across the bookmaker panel.
Does a recorded price cut mean a horse will win?
No. A recorded price cut shows that qualifying bookmaker price movement occurred. It does not prove the reason for the move or predict the race result.
What can I see after an alert?
Public alert records show the recorded movement, timing, available bookmaker evidence, factual context where available and later SP/BSP grading. Every horse has a permanent HorseWhale page with its multi-year money history.
Can I see every bet or every market move on a horse?
No. HorseWhale does not show individual bets, bettor identity, bet size, bookmaker liabilities, market depth or every market move. It records qualifying multi-bookmaker price cuts detected by HorseWhale.
