Paper: no money was at risk. 69 settled bets is a small sample, and a record this short says little about what comes next: in our test of 90 strategies, no early lead held up as its sample grew.

Strategy

Buy heavy favorites in the final hour before a game starts (the pre-game price is the most informed one; the question is whether 80–93¢ favorites are still underpriced). Each run: get_markets({category: "Sports", closes_within_hours: 2, order: "closing", limit: 20}); keep only game-winner markets (moneylines, not spreads or totals) that close in 15 to 90 minutes. Where one side's ask is between 80 and 93 on a book with at least 50 contracts within 3 cents, buy 5 contracts of that side at the ask. One position per game, at most 3 new positions per run. Let positions settle. Sizing is FIXED: every order is exactly 5 contracts (results are compared across a fleet; do not size by conviction). Hold positions to settlement unless the strategy says otherwise. End with a short report: the market you looked at, the numbers you saw, and what you did.

Recent runs

Run complete — no new trades.

  • Scanned Sports markets closing within two hours. The results were dominated by player props, inning markets, and markets closing immediately; no eligible game-winner market was found in the required 15–90 minute window with a qualifying 80–93¢ ask and verified depth.
  • Existing positions reviewed:
  • Prairie View A&M wins: 5 YES @ 88¢; market bid/ask 85/87¢, already past its listed 19:00 UTC close. Held; no exit rule applies.
  • Mirra Andreeva wins set 2: 5 YES @ 80¢; listed close 18:00 UTC, also past close. Held for settlement.
  • No resting orders.

Next run: check settlement/status of both positions first, then scan newly listed Sports game-winner markets closing within 15–90 minutes.

5 stepsSep 6, 18:09 UTC

Run complete.

  • Recorded thesis and reviewed the existing Andreeva set-2 position: still open at 5 YES, with no exit action indicated.
  • Scanned Sports markets closing within two hours.
  • Texas Southern vs Prairie View A&M — Prairie View A&M wins: YES ask 88¢, with substantial depth through 91¢; qualifies as an 80–93¢ heavy favorite and has ample liquidity within three cents. Bought 5 YES at 88¢, fully filled; fee 4¢.
  • FURIA map 3 was 82¢ but lacked the required 50 contracts within three cents, so skipped.
  • Kolninov was 74¢ and outside the entry range, so skipped.
  • No resting orders remain.

Next run: check both open positions and repeat the Sports closing-within-two-hours scan.

Run complete.

  • Recorded thesis before trading.
  • Scanned Sports markets closing within two hours.
  • Most apparent favorites were already closed or had no ask/liquidity, so they were not eligible.
  • Mirra Andreeva vs Anastasia Potapova, Set 2: Andreeva YES ask 80¢, with substantial depth through 83¢; this met the 80–93¢ favorite rule and the 15–90 minute window. Bought 5 YES at 80¢, fully filled; fee 6¢.
  • No resting orders remain. Cash is reduced by approximately 406¢ including fees.
  • Hold the position to settlement. Next run should check this position’s settlement status and repeat the closing-within-two-hours Sports scan.

Run complete. I recorded the thesis and scanned Sports markets closing within two hours.

  • Damian Wasilewski: 89¢ ask, but only 1 contract at the touch and insufficient depth within 3¢, so skipped.
  • WRAITH PCIFIC: 80¢ ask (market quote 81¢), with 34 contracts at 80¢ plus 49 at 81¢ and ample depth through 83¢. This met the 80–93¢ favorite rule, so I bought 5 YES at 80¢; fee 6¢, filled fully.
  • Other displayed markets were outside the qualifying price range or were non-moneyline markets.

Existing Petkovic position remains held to settlement. No resting orders remain. Next run should check settlement status and review the new WRAITH position, then repeat the closing-within-two-hours Sports scan.

4 stepsSep 6, 15:09 UTC

Run complete. I recorded the thesis and scanned Sports markets closing within two hours.

  • Existing Petkovic position: still active despite its listed close having passed; current bid/ask is 78/81¢. I made no exit because the standing strategy is to hold to settlement and no explicit exit condition fired.
  • Wout Van Aert: 94¢ ask, outside the 80–93¢ entry range; only 4 contracts within 3¢.
  • Hugo Car: 79¢ ask, below the required range, so excluded despite strong depth.
  • Other displayed candidates were either extreme 99¢/1¢ markets, not suitable favorites under the rule, or lacked a qualifying 80–93¢ ask/depth setup.

No orders were placed. No resting orders remain. Next run should first check whether Petkovic has settled, then repeat the Sports scan for qualifying game-winner favorites.

5 stepsSep 6, 14:09 UTC

Run complete. I scanned Sports markets closing within two hours and applied the 15–90 minute window.

  • Pavel Lagutin wins: 91¢ ask with strong depth, but it closes at 14:20 UTC—only about 11 minutes away, so excluded.
  • Carlos Sanchez Jover wins: 85¢ ask, but also closes at 14:20 UTC; excluded despite sufficient nearby depth.
  • Mika Petkovic wins: 82¢ ask, closes at 14:30 UTC (~21 minutes away), with substantial depth at 82–84¢. This qualified, so I bought 5 YES at an 83¢ limit, all filled at 82¢. Fee: 6¢.
  • Other candidates were outside the favorite-price range, lacked adequate liquidity, or were not suitable moneyline favorites.

Portfolio is now holding 5 YES Petkovic contracts, with no resting orders. Next run should check whether Petkovic settled and review the position before scanning new entries.

Run complete. I recorded the thesis and scanned Sports markets closing within two hours.

Qualifying candidates were reviewed:

  • Federico Iannaccone wins: ask 89¢, with 922 contracts at 89¢ and substantial depth within 3¢. However, it closes at 13:20 UTC, only about 11 minutes away—outside the required 15–90-minute window.
  • Matisse Bobichon wins: ask 94¢, outside the 80–93¢ target range, despite ample liquidity.

Other markets were either below the favorite-price range, lacked sufficient displayed depth, or were closing too soon. No orders were placed. Portfolio remains flat with no resting orders and +215¢ realized P&L.

Next run: rescan the closing window and first check for any stale exposure or resting orders.

4 stepsSep 6, 12:09 UTC

Run complete. I recorded the thesis and scanned Sports markets closing within two hours.

The only qualifying price-range candidates were:

  • Krutykh YES: ask 90¢, with 704 contracts at 90¢ and substantial depth nearby, but the market closes at 12:10 UTC, essentially immediately and outside the required 15–90-minute entry window.
  • Yokohama YES: ask 96¢, above the 80–93¢ range.
  • O Elvas advances YES: ask 98¢, above range and not a standard game-winner.
  • Two table-tennis favorites had asks of 79¢ and 89¢, but only 1 contract displayed and no meaningful depth.

No orders were placed. Portfolio remains flat with no resting orders and +215¢ realized P&L. Next run should rescan the closing window and verify that no stale exposure or orders has appeared.

4 stepsSep 6, 11:09 UTC

Run complete. I reviewed Sports markets closing within two hours.

The existing Tuncay Duran YES position remains active, with the market closing at 11:10 UTC and no ask currently displayed; I held the 5 contracts as required.

Potential favorites closing around 12:00 UTC included Kia Tigers, Doosan Bears, and Hanwha Eagles, all near 99¢. They do not qualify because the strategy’s entry range is 80–93¢; Hanwha also had no displayed ask. No new positions were opened.

Portfolio remains: 5 Duran YES contracts, no resting orders, approximately 9,715¢ available cash, and +135¢ realized P&L. Next run should first check whether Duran has settled, then scan the closing window again.

5 stepsSep 6, 10:09 UTC

Run complete. The prior Invictus Gaming position is no longer present, indicating it settled; portfolio shows 10,140¢ cash, no positions, no resting orders, and +140¢ realized P&L.

I scanned Sports markets closing within two hours and applied the final-hour favorite strategy. The strongest qualifying opportunity was Tuncay Duran wins (Tokac vs Duran), closing at 11:10 UTC: YES ask 84¢, with 13,860 contracts displayed at the ask and substantial depth within 3¢. I bought the fixed 5 YES contracts at an 84¢ ceiling; all filled at 84¢ with a 5¢ fee.

Other candidates were rejected or not qualifying: Hokkaido Nippon-Ham was 89¢ but had only 70 contracts at the touch and insufficient qualifying nearby depth; Ji Sung Nam was 85¢ and liquid but closes at 11:30 UTC, outside the 90-minute entry window from this run’s timestamp. The Duran position should be held to settlement under the standing strategy. Next run should check whether it has settled and then review the new closing-window scan.
