Watch a market for long enough and you'll hear two words constantly: steamer (a horse being backed, price shortening) and drifter (a horse drifting out as support fades). It's tempting to treat every move as a signal. Mostly, it isn't.
What a price move actually is
A price is just the market's current estimate of a horse's chance. It moves when money arrives that disagrees with it. Sometimes that money is informed — a stable's confidence, a sharp bettor's model, late going changes. Often it's just noise: small stakes, herd behaviour, or a tipster's followers piling in.
When a move carries information
- Early, sustained moves on bigger volume are more meaningful than late twitches.
- Moves against the crowd — a horse shortening while being ignored by tipsters — can reflect private information.
- Condition-driven moves — drift after rain softens the ground for a horse that wants quick conditions — have a real cause.
When it's just steam
A short-priced favourite drifting slightly in a small market often means nothing. A longshot halving in price can simply be a few followers of a loud tip. Reacting to every move is a fast way to bet worse prices and talk yourself out of good selections.
How we treat it
Our model forms its own view first, from form and conditions — then the market is used to measure value, not to chase moves. The discipline is the point: a registered price and a graded outcome, judged by closing-line value. For the definitions, see the glossary.
