Run complete — 2026-09-02 21:22 UTC.
Reviewed the portfolio and Sports markets closing within 24 hours. The existing position remains Hanyi Liu YES, 5 contracts at 16¢, marked 8¢; it is being held to settlement under the long-shot strategy.
The only clear game-winner market surfaced was WBT vs. Donstu Esports, closing at 21:30 UTC—about eight minutes away and therefore far inside the 30-minute skip window. Donstu’s displayed YES ask was 34¢, above the 12–28¢ entry range; the other side was not a qualifying cheap-side setup. The remaining listings were totals, player props, or other non-game-winner markets, many closing imminently.
No orders were placed. No resting orders remain. Next run should first check whether the Liu market has settled, then scan for newly eligible game-winner markets with sufficient depth and adequate time before start.
Run complete — 2026-09-02 20:22 UTC.
Reviewed Sports markets closing within 24 hours and confirmed the portfolio:
- Hanyi Liu YES: 5 @ 16¢, marked 8.5¢
- RIZON Cherry YES: 5 @ 18¢, marked 1¢
No new positions were placed. The visible candidates were unsuitable: most markets were advance/map markets rather than qualifying game-winner markets, and the only plausible cheap side checked lacked sufficient near-ask depth. Francesinhas map 3 had a 56¢ ask with only 1 contract at touch and no qualifying 12–28¢ entry; Hoogeveen advance was 89¢ with no cheap-side setup. Markets closing at 20:30 UTC were also too close to closing for a new entry.
No resting orders remain. Continue holding both existing positions to settlement. Next run should first check whether either held market has settled, then scan newly eligible Sports game-winner markets and verify start timing, ticks, and depth before trading.

Reviewed the Sports markets closing within 24 hours and confirmed the portfolio. Existing positions remain unresolved and are being held to settlement per strategy:
- Hanyi Liu YES: 5 @ 16¢, marked 8.5¢
- Glacial Guardians YES: 5 @ 21¢, marked 1¢
- RIZON Cherry YES: 5 @ 18¢, marked 1¢
No resting orders remain; the previously reported RIZON remainder is no longer resting, indicating the full position was filled.
The available closing markets were either non-game-winner props, effectively settled/near-certain advance markets, too close to closing, or lacked a qualifying 12–28¢ long-shot with sufficient depth. No new entries were placed. Next run should first check whether the three held game markets have settled, then scan newly eligible Sports game-winner markets and verify timing, ticks, and order-book depth before any entry.
Run complete — 2026-09-02 18:22 UTC.
Scanned Sports markets closing within 24 hours. The existing Hanyi Liu position remains unresolved and was held to settlement.
Eligible game-winner candidates:
- Glacial Guardians YES: 21¢ ask, with 16 contracts at 21¢ and substantial additional depth nearby. Bought 5 YES at 21¢; filled fully, 6¢ fee.
- RIZON Cherry YES: 18¢ ask, but only 2 contracts available at the touch. Bought 5 at an 18¢ ceiling; 2 filled at 18¢ with 3¢ fee, while 3 contracts remain resting at 18¢.
- UCAM YES: 19¢ ask, but only 5 at the touch and the market did not meet the required 50-contract depth within 3¢, so skipped.
No other entries placed. Next run should review the resting RIZON order first, then check all positions and whether Liu or the newly entered matches have settled.

Reviewed the existing Hanyi Liu position: 5 YES @16¢, currently marked 7.5¢. The market remains active despite its listed close time and is unresolved, so I held it per strategy.
Scanned Sports markets closing within 24 hours. The only qualifying long-shot moneyline-style candidate was Oliwier Sterniczuk: YES ask 17¢ with 105 contracts at 17¢ and additional depth at 18¢. However, it closes at 17:30 UTC—about eight minutes away—so it fails the strategy’s 30-minute minimum horizon and was skipped. Lilli Tagger’s set-2 market had a 27¢ ask and strong depth, but was not a full-match moneyline and was also too close to closing.
No orders placed. Cash remains 7,767¢; no resting orders. Next run should check Liu’s settlement first, then scan newly eligible Sports markets and avoid markets too close to start or close.
Run complete — 2026-09-02 16:22 UTC.
Existing Liu (5 YES @16¢) and Marko (5 YES @24¢) positions remain active and unresolved despite their listed close times; held to settlement per strategy.
Scanned Sports markets closing within 24 hours. Most candidates were unsuitable: asks outside the 12–28¢ range, insufficient qualifying depth, or non-moneyline/late markets. Pucinelli de Almeida qualified: YES ask 18¢, with substantial depth (1,167 at 18¢ and 916 at 19¢), and closes at 17:10 UTC. Bought the fixed 5 YES contracts at a limit of 18¢; all filled at 18¢ with a 6¢ fee.
Portfolio now holds Liu 5 YES, Marko 5 YES, and Pucinelli de Almeida 5 YES. No resting orders. Next run should check settlement/results for all positions first, then scan newly eligible Sports moneylines and avoid entries too close to start or close.

Existing Liu (5 YES @16¢) and Marko (5 YES @24¢) positions remain active/unsettled despite their listed close times; per strategy, both are held to settlement.
Scanned Sports markets closing within 24 hours. Most candidates either had asks above the 12–28¢ long-shot range, insufficient qualifying depth, or were not suitable moneyline entries. BIG in Nemiga vs BIG qualified: YES ask 16¢, with at least 50 contracts within 3¢, and the market closes at 16:00 UTC. Bought the fixed 5 YES contracts at a limit of 18¢; all filled at 16¢ with a 5¢ fee. No resting orders.
Portfolio now holds Liu 5 YES, Marko 5 YES, and BIG 5 YES. Next run should first check settlement/results for all three positions, then review newly eligible Sports markets and avoid entries too close to their start/close.

Reviewed Sports markets closing within 24 hours and the two existing holdings. Liu’s market closed earlier at 07:10 UTC but remains active/unsettled with no result; Marko remains active and closes at 15:00 UTC.
No new position was opened. The apparent candidates failed the strategy filters: Kolar/Poljak had a 15¢ displayed ask but only 100 contracts at 21¢ (not 50 within 3¢ of the ask), while B8 had a 13¢ ask but insufficient qualifying depth within 3¢ after applying the actual book. Both markets also close too soon for the required 30-minute pre-start buffer. Marko’s existing 26¢ ask is not a new entry, and the position remains held to settlement.
Portfolio remains: 5 YES Liu @16¢ and 5 YES Marko @24¢; no resting orders. Next run should first check whether Liu and Marko have settled/results, then scan the closing Sports list and verify start-time buffer, moneyline classification, and depth before any entry.
Run complete — 2026-09-02 13:22 UTC.
Reviewed current portfolio: Liu remains marked 7¢ and Gretskiy 34¢; neither was exited because the strategy holds positions to settlement. No resting orders were present.
Scanned Sports markets closing within 24 hours. Most candidates either lacked sufficient depth, were outside the 12–28¢ entry range, or were not qualifying moneylines. Marko wins qualified at a 24¢ ask, with 176 contracts at 24¢ and substantial additional liquidity through 27¢. Bought the fixed 5 YES contracts at 24¢, fully filled; fee was 7¢. No other entry was made.
Next run should check the three holdings for settlement/results, then repeat the Sports scan and verify game timing and depth before any new entry.

Run complete — 2026-09-02 12:22 UTC.
Scanned Sports markets closing within 24 hours. Ivan Gretskiy wins qualified at a 23¢ ask, with 124 contracts at 24¢ and substantial depth within 3¢. Bought 5 YES, filled across 23–24¢ (blended cost 23.2¢; 7¢ fee), using the fixed long-shot size.
Other candidates did not qualify: Singh was 30¢ (above the 12–28¢ range), and Inner Circle was 30¢. Existing Milic and Liu holdings remain intended holds to settlement. No resting orders. Next run should check settlements/results first, then scan newly eligible Sports moneylines and verify start-time buffer and order-book depth.
