This story covers a single signal — right now the member board has 608 live signals across 268 matches, found the same way.
The setup — the analysis as published at detection, written before the game and frozen for the record. The market it describes has since closed; the outcome is above.
At detection, the moneyline market for Anton Shepp vs Mark Ceban (ATP Challenger Tour) carried a pricing gap: Duel's decimal 2.88 sat 11.8% above the sharp consensus. The algorithm surfaced this inefficiency before the match, opening a window for bettors to execute at that level.
Match outcome: 0–2 in favor of the flagged side. The bet returned +1.88 units on a flat 1-unit stake.
The metric that matters in portfolio construction: closing-line value. Between detection and kickoff, the market had repriced +2.0% toward the flagged outcome—systematic movement that professionals measure across time because individual results are volatile while pricing efficiency compounds.
Tennis moneyline signals in this odds range have accumulated +6.0% ROI across 3131 settled detections on the board.
The algorithm that generated this detection runs before kickoff each day and surfaces mispricings while execution remains available. The live board displays flagged edges during the window, not after settlement.
Historical, aggregate data on settled bets — not betting advice and not a guarantee. Markets adapt; edges fade; variance is real.
