BettingSignals watches Pinnacle and Betfair odds for football and basketball around the world, updates them in milliseconds, and sends an alert only when a price drop passes our checks for size, speed, money, and context.
This page explains each step, what an alert contains, how we measure whether signals work, and where their limits are.
We share our methodology because a signal is only useful when you understand where it comes from. Knowing what we track, what we filter out, and how we score our own results lets you judge every alert for yourself instead of following it blindly.
Why We Track Pinnacle and Betfair
Most bookmakers don’t set their own prices from scratch. They watch the market leaders and copy their moves, often a few minutes late. Tracking the bookmakers that move first tells you far more than tracking the ones that follow.
Pinnacle runs low margins and accepts large bets from winning players instead of limiting them. Its prices are shaped by some of the best-informed money in the market, which is why other bookmakers treat Pinnacle as a reference.
Betfair is an exchange. Bettors set the prices by betting against each other, and every price comes with the amount of money matched at it. That makes Betfair a direct view of where real money is going.
Together they give two independent readings of the same market: one from a bookmaker built around informed bettors, one from the bettors themselves. For a beginner-friendly introduction to how prices move, read What Are Dropping Odds.
Step 1: How We Track the Market
Our system follows Pinnacle and Betfair odds across football leagues and basketball competitions all over the world. Every price change is recorded the moment it happens, with updates measured in milliseconds.
For each market we store the opening price as a fixed baseline. Every later move is measured against it, so a drop always means the same thing: how far the price has fallen since the market opened, not since the last refresh.
Speed matters because the gap between the market leaders and slower bookmakers is often a few minutes or less. An alert that arrives after other bookmakers have adjusted is information, not an opportunity.
Step 2: How We Filter Out the Noise
Most price changes don’t mean anything. Bookmakers adjust margins, rebalance their books, and nudge prices all day. Our model weighs five factors before a move becomes a signal.
| Check | What we look at | Why it matters |
|---|---|---|
| Size of the drop | How far the price has fallen from the opening odds | Small wobbles are routine; big moves usually have a cause |
| Speed of the drop | How quickly the price fell | A fast drop points to new information or a large bet; a slow drift is often normal balancing |
| Betting volume | How much money is matched on Betfair around the move | A move on thin volume is easy to push and more likely to bounce back |
| Lineup and injury news | Whether confirmed team news has just been released | News explains a move and helps you judge whether the new price is fair |
| Bookmaker limits | How much Pinnacle accepts on the market at that moment | The higher the limit, the more money it took to move the price |
Size: why a percentage alone can mislead
The same percentage means different things at different prices. A drop from 1.50 to 1.40 is only 6.7%, but it raises the implied probability from 66.7% to 71.4%. A drop from 5.00 to 4.50 is 10%, yet the implied probability only rises from 20.0% to 22.2%. A move becomes an alert only when it passes.
Limits: early moves vs late moves
Pinnacle usually accepts smaller bets when a market first opens and raises its limits as the start approaches. A drop days before a game can be moved by relatively little money. The same drop an hour before kick-off or tip-off, when limits are highest, needed much more, so it carries more weight.
What we ignore
Routine margin changes, small adjustments that reverse within minutes, and moves on markets with too little money behind them don’t trigger alerts. The strongest signals tend to appear at Pinnacle and Betfair at the same time, a pattern bettors call a steam move.
Step 3: What Every Alert Shows
Each alert gives you what you need to decide in seconds, and nothing else.
Example alert
| Field | Example |
|---|---|
| Match | Team A vs Team B |
| Date & Time | Calendar |
| League | Name of the league |
| Type | Moneyline/Spread |
| Opening odds | 2.40 |
| Current odds | 1.95 |
| Drop | 18.75% |
| Limit per click | $300 |
To read it, open your own bookmaker and look at the price for the same market. If it is still close to the opening odds, the market hasn’t caught up yet and there may be value. If it is already near the current odds, the opportunity has gone, and the right move is to skip it.
How We Measure Signal Quality
Win rate is a poor test of a signals service. Over a few weeks, luck dominates: good bets lose and bad bets win. We use closing line value (CLV) instead.
The closing line is the last price before the game starts. By then, the market has absorbed all the team news and money, so it is the most accurate price available. If you regularly get better odds than the closing line, you are very likely making good bets, whatever the short-term results say.
CLV = (your odds ÷ closing odds) − 1
If you bet at 2.10 after an alert and the game closes at 1.95, your CLV is (2.10 ÷ 1.95) − 1 = 7.7%.
For every signal, we record the price at the moment of the alert and the closing price, and publish both in our statistics. Since last year, nearly +4,000 units in total profit recevied through our premium channel.
How to Use a Signal
A signal tells you the market has moved. Whether a bet is worth placing depends on the price you can still get.
- Work out the fair price. Bookmaker odds include a margin. In a two-way market priced at 1.91 on both sides, each side implies 52.4%, adding up to 104.7%. Remove the extra and each side is really 50%, so the fair odds are 2.00.
- Compare it with your bookmaker. If your bookmaker still offers 2.10 on a side whose fair price is 2.00, you are getting about 5% more than the price is worth. If it offers 1.95, there is no value left, however big the drop was.
- Keep stakes small and fixed. Use the same stake on every bet. It keeps decisions fast and protects your budget through losing runs.
- Record every bet. Note the odds you took, the closing odds and the result. After a few hundred bets, your CLV will show whether the approach is working for you.

Limits of Our Method
No signals service can remove the risk from betting, and we would rather you know the limits up front.
- The market can be wrong. A drop shows what Pinnacle and Betfair believe, not what will happen. Plenty of heavily backed outcomes still lose.
- Prices can bounce back. Sometimes odds fall and then return to where they started, for example when an injury worry turns out to be false.
- Thin markets are harder to read. In lower leagues and smaller competitions, less money is matched on Betfair, so moves are less reliable.
- Your timing matters. Alerts arrive fast, but placing the bet still takes time, and the price may move before your bet is accepted.
- Bookmakers may limit you. Some bookmakers restrict accounts that regularly bet on these moves.
Signals are information, not advice. Use them as one input alongside your own judgement, and only stake what you can afford to lose.
Frequently Asked Questions
Which bookmakers does BettingSignals track?
Pinnacle and Betfair. They are the two prices most other bookmakers follow, so moves there usually show up first.
Why don’t you send an alert for every odds drop?
Because most drops are noise. Each move has to pass our checks for size, speed, betting volume, team news, and bookmaker limits before it becomes a signal.
How fast are the alerts?
Odds updates are measured in milliseconds, and alerts go out as soon as a move passes our checks.
Do signals guarantee a profit?
No. Signals help you find prices that may be better than the market’s latest view, but every bet can lose. We measure quality with closing line value over hundreds of signals, not with promises.
