What is a market signal?

Not every movement is a signal

Thousands of odds move every day, for all sorts of reasons. Most of the changes are small, short-lived or invisible unless you're looking. So not every movement deserves the same attention, and that's where the idea of a signal comes in.

Every signal is a movement. Plenty of movements never become signals.

What is a market signal?

A market signal is a movement with enough notable features to justify a closer look.

It's a way of sorting movements, nothing more. It promises nothing about the result and it isn't a tip.

The 5 features of a signal

When a movement catches the eye, it's rarely because of one thing. Several factors usually work together:

• size
• speed
• timing
• agreement between bookmakers
• consistency

Size

Size is how far the price has moved. A tiny shift rarely gets much notice, while a big one does. The more pronounced the movement, the more it tends to be worth watching.

Speed

Speed is how quickly the movement happens. A slow drift over several days doesn't say the same thing as a large shift within minutes. The pace is part of the picture.

Timing

When a movement appears often matters as much as the movement itself. A shift several days before a match isn't read like one just before kickoff. Context counts.

Agreement between bookmakers

A steam move happens when several bookmakers move at the same time. That usually draws more attention. The market seems to be converging on one reading of the event, which people call alignment or consensus.

Consistency

A signal gets more interesting when several indicators tell the same story. Say several bookmakers move the same way, the shift is fast and the timing is unusual. Taken together, those three say more than any of them alone. I give that kind of agreement more weight than any single feature, because a big move at one bookmaker can be an outlier.

Not every signal has the same strength

Signals come in sizes. Some barely register. Others are hard to ignore. The gap usually comes from how many notable features show up together.

Why some signals draw more attention

A move seen at two bookmakers and one seen at twenty don't carry the same weight. The more notable criteria a movement combines, the more attention it gets from people who follow the market.

What to look at first

When a movement appears, these five checks come first:

• its size
• its speed
• how many bookmakers are involved
• the moment it appears
• whether the market as a whole is consistent

You're not hunting for certainty. You're deciding whether the movement deserves more of your time. That's a different question from expected value, which you'd still need to weigh before a stake means anything.

Examples of signals: football, tennis, basketball

These are made-up examples.

In football, a price that slips from 2.00 to 1.98 over several days, with few bookmakers following, is a weak signal. The movement exists, but it has almost none of the features of a strong one. A good chunk of the market looks exactly like this, and it's easy to forget that when you're hunting for something exciting.

A football price that drops from 2.10 to 1.85 within minutes, close to kickoff, with several bookmakers making the same adjustment, is a strong signal. That combination usually gets noticed.

In tennis, a price that goes from 1.90 to 1.55 within minutes, just before the match starts, while several bookmakers follow, is also strong. The very late timing adds to it.

In basketball, a price that edges from 1.80 to 1.75 over several hours, with few bookmakers adjusting, is a weak signal. It moves, but only a little.

What a signal never guarantees

A signal isn't a prediction. It doesn't announce a result and it guarantees nothing. It's also a different thing from a value bet: a signal describes how the market is moving, while a value bet is a price judged wrong against a probability estimate.

All it says is that a movement deserves more attention than average.

No single indicator makes a signal

A big movement on its own may not mean much. The same goes for agreement between bookmakers, or a fast shift. It's usually several pieces together that turn a movement into a real signal. An isolated one often tells you little, and once several notable features line up, the level of attention tends to go up.

The most common mistakes

Five mistakes come up again and again among people who follow the market:

• believing a signal predicts a result
• watching a single bookmaker
• ignoring context
• mixing up a movement and a signal
• analysing one indicator in isolation

How OddScore analyses signals

OddScore compares odds from several bookmakers, removes the margin and tracks how the prices change. It then calculates a signal from 0 to 100, which sums up the pressure of the market.

It gives no staking advice. The AI reading summarises what the market is saying before the match, and it isn't a bet to follow. The aim is to help you understand the market, not to predict it.
