Understanding first-half goals markets
A first-half goals market concerns a defined match period, not the final score. Its estimate, evidence, and settlement must remain separate from full-match goals.
Reading the line
A first-half total compares the goals scored by both teams before halftime with a stated line. Over 0.5 first-half goals requires at least one goal in that period. Over 1.5 requires at least two. The half-goal avoids a tie on the line.
Hypothetical teaching examples: a halftime score of 1–0 wins Over 0.5 but loses Over 1.5. A halftime score of 1–1 wins both. Goals scored after the second half begins do not repair a losing first-half selection, even if the final match total is high.
What DeePicks publishes
The current DeePicks prediction contract treats first-half goals as a distinct market and supports exactly two match-total lines: Over 0.5 and Over 1.5. An available section must contain both probability fields. If the model or required input is unavailable, the section carries an explicit unavailable reason instead of a fabricated percentage.
That separation prevents the interface from deriving a first-half number from a full-match estimate. A match can have a strong full-time scoring outlook while remaining uncertain or unavailable for the opening period. AVAILABLE confirms that the required fields passed the application contract; it does not prove that the probability is calibrated, accurate, or profitable.
Why the first half behaves differently
The period is shorter, and match state has less time to evolve. Team approach, an early goal, a red card, injury time, or a tactical change can alter what happens before halftime. Historical full-match averages do not automatically describe the distribution of first-half goals.
A model estimate is therefore an uncertain pre-match assessment, not a countdown or guarantee. A displayed 60% estimate does not mean a goal is 60% complete, and a run of recent early goals does not require the next match to follow the same pattern.
Settlement boundaries matter
Bookmaker rules define the relevant period, the treatment of stoppage time, and what happens if a match is abandoned or played in an unusual format. Bet365's published soccer half-market rules say first-half goals bets are no action when a match is abandoned before halftime unless settlement is already determined. Betfair's football rules state that unusual formats such as three or four periods void half-time markets.
Those are examples from specific operators, not universal rules. Another bookmaker, competition, or named market may use different wording. Check the rules attached to the exact bet before relying on a general explanation, particularly for abandonments, shortened matches, neutral venues, extra time, and retrospective corrections.
Missing scores are not 0–0
When DeePicks’ Bet Tracker manually evaluates a first-half goals selection, it requires both the first-half home score and first-half away score. If either is missing, the selection needs review. The application does not turn the absent value into zero, because “not supplied” and “no goal” are different facts.
The same discipline applies before kickoff: no published first-half estimate should be read as a low estimate, and an unavailable prediction should not be used as a filler leg. Keep the period, line, timestamp, and source attached to the number, and treat every model estimate as uncertain.
