Steamers vs drifters: what the data actually shows

"Steamer" describes a horse whose price is shortening. HorseWhale doesn't publish a steamers list — it records every panel-wide cut as a graded, permanent event tied to the horse, not a leaderboard that resets each day.
What makes the pre-move price different from the moved price
A steamer can be backed at the price before the bulk of the market adjusts, or at the price it has already moved to. Those are different prices for the same horse.
HorseWhale calls this a gamble. Money Flow measures it, 0 to 100: high means money arriving, low means money leaving.
That gap is not about the horse. It is about price. A horse that was 5/1 (6.0) and is now 3/1 (4.0) is the same horse at either price. The question is whether the price you are taking reflects what the market already knows, or what it is in the process of discovering. Source: Geegeez, Steamers and Drifters Part 2.
How to spot a move while it is still spreading
A move in progress has a distinctive signature. It does not start everywhere at once. One or two bookmakers cut first; others hold at the earlier price for a few minutes before following. During that window, the same runner shows different prices across the panel — which is the observable signal that something is happening, and that not every bookmaker has yet decided it is happening.
Watching a single bookmaker will not catch this — you see one cut but not whether anyone else has moved. Watching the whole panel simultaneously and measuring the spread of the cut is the relevant measurement. That is the mechanism HorseWhale uses: an alert fires when a cut starts spreading across the panel, naming which bookmakers are still at the earlier price. The alert is not a selection — it is information about a price differential that exists right now.
Common questions
What's the difference between a steamer and a drifter?
They are the two sides of one market. A horse whose price shortens as money goes on it is what HorseWhale calls a gamble; a drifter's price lengthens as money stays away. Money Flow measures it, 0 to 100: high means money arriving, low means money leaving.
How can I spot a price move early rather than after it has finished?
HorseWhale reads 25+ UK and Irish bookmakers across the whole racing day, and the racecard shows each move while it is still spreading. Every recorded move is graded in public against the result, and every horse has a permanent money-history page.
Does an early price move mean the horse will win?
No. A price move is a fact about the market, not about the horse. Money Flow measures what the money is doing. Horses that are backed lose every day.
