The minimum live-information contract
The Gambling Commission's in-play technical standard requires Great Britain remote operators to warn customers that live information may be delayed and that other participants may have more current information. A television picture, app event feed, price screen, operator engine, and accepted ticket can therefore represent different moments.
Record these fields before interpreting any result:
| Field | Minimum record |
|---|---|
| Match state | Score, clock, period, player count and known review state |
| Observation time | UTC timestamp and source for each event or statistic |
| Price time | Displayed-price timestamp, if available |
| Execution | Submitted price, accepted price, matched size and acceptance time |
| Contract | Market, line, qualifying period and current settlement rule |
| Information quality | Feed source, delay warning, missing fields and correction policy |
| Exposure | Stake, liability, other open positions and total possible loss |
The Betfair historical feed specification illustrates why market status, publish time, available prices and traded volume belong in an exchange record. These fields describe an exchange feed, not every sportsbook interface.
A live price is not a match explanation
An in-play price is a contractual quote at a moment in time. It can move because time has elapsed, the score or player count changed, new information entered a model, available orders changed, a market reopened, or an operator changed its offer. The peer-reviewed Bayesian in-play football model is one documented method for updating outcome probabilities as a match progresses; it does not establish why any particular commercial price moved.
Separate three questions:
- What did the match data show at the decision cutoff?
- What probability did the declared method produce from that data?
- What price and size were actually available and accepted?
Only the third question determines the ticket. The first two support analysis, and they may be wrong, delayed, or incomplete.
Build a no-action result into the method
No action is an essential possible outcome. Stop the process when the match state is uncertain, a material event is under review, the price changes beyond a predeclared bound, the required size is unavailable, the accepted receipt differs from the intended contract, or the total exposure would exceed the preset limit.
In-play participation deserves particular restraint. A cross-sectional Ontario study found an association between in-play participation and higher self-reported gambling harms, while explicitly stating that its design cannot establish causation (Journal of Behavioral Addictions). That evidence supports caution, not a diagnosis about an individual reader.
Money and time controls come first
Set the session's affordable maximum loss and end time before viewing live prices. The Gambling Commission's financial-limits standard documents customer-set limit requirements for licensed remote operators in Great Britain. A preliminary real-time study of in-play bettors associated monetary-limit use with lower betting intensity and harms, while findings for time limits were mixed (Addictive Behaviors).
Do not increase a limit, add a market, or extend a session to recover a result. The research guides in this collection are methods for recording and testing claims; they are not prompts to place a bet.
Assumptions and limitations
This collection is educational and Great Britain oriented. Operator interfaces, delays, market availability, limits, rules and settlement can differ by jurisdiction and product. Research findings describe particular samples and methods and do not prove that in-play betting causes harm or that any strategy produces a positive return.
