How HorseWhale works

HorseWhale is Racing's Money Record: a market monitor with memory for UK and Irish racing. It watches 20+ bookmakers, records qualifying alerts and their observed market paths, adds factual reasons and risks where the horse's history supports them, grades every alert against SP and BSP, and keeps the permanent record public.

What HorseWhale watches

HorseWhale monitors advertised bookmaker prices across 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 receipt records 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 receipt 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

Horses with recorded qualifying alerts have permanent HorseWhale record pages. Those pages retain the horse’s recorded alerts and link to the underlying public receipts.

What HorseWhale is not

HorseWhale records market signals and historical evidence. It does not provide tips, selections 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 receipts show the recorded movement, timing, available bookmaker evidence, factual context where available and later SP/BSP grading. Horse pages retain the record for horses with qualifying alerts.

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, exchange matched volume, liquidity, market depth or every market move. It records qualifying multi-bookmaker price cuts detected by HorseWhale.
