The terms below appear across fixture pages, in-play output, and prompt results. The full betting glossary covers the wider vocabulary.
xG (Expected Goals). The number of goals a team is expected to score in a fixture, based on attacking and defensive ratings, the opponent, venue, and recent form. An average across many simulated versions of the fixture, not a prediction of a single result.
Fair odds (true odds). The minimum price you would take on an outcome, based on the model, and still be getting value. Calculated from the model’s probability: a 50% chance gives fair odds of 2.00.
Sanity Score. The model’s confidence in the analysis, from 0 to 10 with 10/10 the maximum. Built from four components shown in the Sanity table on every analysis: model variance, data freshness, market consistency, and divergence assessment. Read it alongside +EV.
EV (Expected Value). The gap between the fair odds and the bookmaker’s odds, expressed as a percentage. Market odds above fair are +EV; below fair are -EV.
Edge. The proportional advantage the model identifies on an outcome. Closely related to EV and moves in the same direction.
Recommendation. The analysis conclusion the model surfaces for a market. Not an instruction to bet; the decision and stake stay with you.
Minimum fair price. Gecko Edge does not issue recommendations when market odds are below 1.20, whatever the EV shows.
BTTS (Both Teams To Score). The market on whether both teams score at least once. The Yes and No probabilities sum to 100%.
AH (Asian Handicap). A market that adjusts the scoreline by a handicap, removing the draw and producing a two-way bet. Lines come in whole, half, and quarter goals.
FH / FT (First Half / Full Time). Whether a market covers the first 45 minutes only or the whole match.
Overdue (in-play). The gap between chance creation and goals scored in the live match. The model adjusts the live xG figure and compares it against goals scored; the wider the gap, the more overdue the match, and the more weight the analysis gives to the next goal.
Divergence flag. Fires when the model and the market price the same outcome very differently. An instruction to look closer, covered in its own entry.
Goal Pressure Verdict (in-play). The in-play system’s read on how likely the next phase of play is to produce a goal. It decides whether an InPlay Analysis routes to a goal-line projection or a direct recommendation.
