How to Read VigBreak Signals
Each signal on VigBreak shows a betting opportunity detected by the system. Here is what the numbers and labels mean, and how to use the information.
What a signal shows
Each row on the signals page represents one detected opportunity. The columns are:
Sport. A coloured tag showing the sport (e.g. Football, Tennis, Basketball).
Event. The teams or players involved, plus the competition name.
Type. EV (positive expected value) or ARB (arbitrage). These work differently and the columns for each differ slightly.
Book(s). For EV signals, the bookmaker offering the value. For ARB signals, all bookmakers involved.
Edge. For EV signals, this is the edge percentage. For ARB signals, this is the guaranteed profit percentage.
Odds. The bookmaker odds at the time the signal was detected. For ARB signals, the odds for each leg.
Kickoff. How long until the event starts, or whether it has already started.
Status. Whether the signal is still available, whether odds have moved, or whether the event has started or finished.
Detected. How long ago the signal was first detected.
Clicking a row opens a panel with more detail, including the selection name, market type, the calculated true odds used for comparison, and the signal ID.
Edge percentage explained
For EV signals, the edge percentage is how much better the bookmaker's current odds are than the estimated fair price. If the fair price is 2.00 and the available odds are 2.10, the edge is 5%.
The formula is: edge% = (bookie odds / fair odds - 1) × 100.
A 3-5% edge is solid. Above 8% on a mainstream market is unusual and worth a second look at whether the odds are genuine. Signals below our minimum edge threshold are filtered out before reaching the signals page.
For ARB signals, the profit percentage is the guaranteed return expressed as a percentage of the total stake, assuming you split the stake optimally across all legs. A 2% arb on £100 total stake returns £2 profit regardless of the result.
Signal statuses
Available. The odds are still live at the bookmaker and the event has not started. This is the only status where action is still possible.
Odds Gone. The bookmaker has moved or removed the price. The opportunity no longer exists. The signal is kept in the history so you can see what was available.
No Edge. For EV signals, this means the odds are still there but they have moved enough that the edge is no longer sufficient. The bookmaker price is still available but is no longer positive EV versus the reference.
Event Started. The event has kicked off. Whether or not odds are still available, the signal is past its useful window.
Completed. The event has finished. If a paper bet was placed on this signal, the result is recorded.
The default view shows only Available signals. Use the status filter to see the full history.
EV signals vs arb signals
EV signals are one-sided. You back a single outcome at a soft bookmaker because our sharp reference suggests the odds are too generous. The signal might say: Bet on Team A to win at 2.30, when the sharp market prices them at 2.10. The edge is 9.5%.
The outcome of the event determines whether you win or lose. Over many bets, positive EV should produce a profit.
ARB signals are two-sided (or three-sided for draw markets). You back all outcomes simultaneously across two or more bookmakers. The signal shows both legs: Back Team A at Bet365 (2.20) and Back Team B at Ladbrokes (2.20), guaranteed profit 9.9%.
No matter what happens in the match, the arb returns the profit percentage shown, provided you place all legs at the listed odds before they move.
From signal to bet
VigBreak is an information service. It detects and publishes signals. The decision to place a bet, and the responsibility for doing so within your jurisdiction's laws and within your bookmaker's terms, rests with you.
For EV signals: go to the listed bookmaker, find the market and selection, confirm the odds match what is shown, and place your bet. Act quickly. EV signals can disappear in minutes as bookmakers adjust.
For ARB signals: you need to place all legs simultaneously (or as close to simultaneously as possible). Start with the leg that is most likely to move. Some bettors place the riskiest leg first and the safest leg second.
Use the EV calculator to verify the edge on any bet, or the arbitrage calculator to confirm a profit and calculate your stake split.
VigBreak also runs a paper-trading bot that automatically logs simulated bets on qualifying signals. The full history is public on the bets page and the stats page, so you can see exactly how the signals have performed over time.
