Understanding football cards markets
A cards line is meaningful only with its counting and settlement rules attached. The same match incidents can produce different totals under different operator definitions.
What a total-cards line asks
A match-total cards market compares the count recognised by the bookmaker with a stated line. Over 2.5 requires a qualifying count of at least three; Over 3.5 requires at least four. Because the line uses a half, the total cannot land exactly on it.
Hypothetical teaching example: if an operator's final recognised count is four, Over 3.5 wins and Over 4.5 loses. That example explains the threshold only. It does not say which real-world cards the operator will count.
Yellow and red cards are not counted universally
Operator rules can differ even for apparently similar “total cards” markets. Betfair's football rules state for its Over/Under Total Card markets that a yellow is one card, a red is one, and a player's maximum is two. Bet365's card-market rules state that a yellow is one, a red is two, second yellows are ignored, and the maximum per player is three.
That difference is enough to change settlement in some matches. Rules may also specify whether cards to substitutes, substituted players, managers, or coaching staff count; how halftime cards are assigned; and whether post-whistle cards are excluded. A generic event feed is not a substitute for the bookmaker's named settlement source and market rules.
What DeePicks represents
The current DeePicks contract exposes a match-total cards market with Over 2.5, Over 3.5, Over 4.5, and Over 5.5 probability lines when that market is AVAILABLE. It does not publish player-card selections, card points, time-of-first-card markets, or a bookmaker-specific return.
The percentage is a model estimate for the labelled line. It is not a promise that the source data and a bookmaker will classify every incident identically. AVAILABLE means the required model output passed DeePicks’ contract checks; it is not proof of calibration or historic profitability.
Why cards can be difficult to model
Cards depend on more than team averages. Referee approach, rivalry, match importance, tactics, game state, dissent, time-wasting, and a late confrontation can materially change the total. A red card may also change the remaining style of play. Historical information can support an estimate but cannot guarantee how the next referee decision will be recorded.
Provider corrections matter as well. Betfair states that some incident markets use its feed-provider data, while William Hill's football rules identify Opta for stats-market settlement. Always check the operator's current rule page because the settlement source and correction policy belong to the wager, not to DeePicks.
Missing totals require review
DeePicks does not treat an unavailable cards prediction as zero probability. Likewise, Bet Tracker's manual settlement requires a cards total for a cards selection; if that statistic is absent, the leg remains in NEEDS_REVIEW instead of being graded against zero.
Before interpreting a card estimate, confirm the fixture, period, exact line, model timestamp, and source label. Before interpreting a real wager, separately confirm the bookmaker's treatment of reds, second yellows, non-playing personnel, halftime incidents, abandonments, and later data corrections. Model estimates are not guarantees, and bookmaker rules—not the model label—control settlement.
