Run complete. Reviewed KXBTC-26SEP0218, closing at 22:00 UTC—about 33 minutes away and within the required window.
The nearest/current bin was B77350 ($77,300–$77,399.99). Its live book showed a 20¢ bid / 23¢ ask, with 200 contracts at the ask. Since the ask was below the 55¢ entry threshold, I bought 5 YES contracts with a 25¢ limit (2¢ above the ask), subject to marketable execution and the fixed sizing rule.
No resting orders were present beforehand. Next run should check whether the position filled and hold it to settlement unless strategy instructions change.
Run complete. Reviewed KXBTC-26SEP0217, closing at 21:00 UTC (about 33 minutes away). The nearest/current bin was B77375 ($77,250–$77,499.99). Its book showed a 55¢ bid / 56¢ ask, with 201 contracts displayed at the ask.
Per strategy, the ask exceeded the maximum 55¢ entry threshold, so I did not trade. No resting orders or positions remain. Next run should check the portfolio and select the next KXBTC event closing 20–40 minutes away.
Run complete. Reviewed KXBTC-26SEP0216, closing at 20:00 UTC, about 33 minutes away. The nearest/current bin was B77450 ($77,400–$77,499.99). Its order book showed a 5¢ bid / 7¢ ask, with 300 contracts displayed at the ask.
Because the ask was below the 55¢ threshold, I bought the fixed 5 YES contracts with a 9¢ ceiling. All 5 filled at 7¢, with a 3¢ fee; total cost was 38¢. No resting order remains. Hold to settlement per strategy.
Next run should check this position and select the next KXBTC event closing 20–40 minutes away.

Run complete. Reviewed KXBTC event KXBTC-26SEP0215, closing at 19:00 UTC, approximately 33 minutes away and within the entry window. The nearest/current bin was B77450 ($77,400–$77,499.99). Its live order book showed a 25¢ bid / 26¢ ask, with sufficient displayed liquidity.
The ask was below the 55¢ threshold, so I bought the fixed 5 YES contracts with a 28¢ ceiling. All 5 filled at 26¢, with a 7¢ fee; no resting order remains. Total position cost including fee was 137¢. Hold to settlement per strategy. Next run should check the portfolio and then select the next KXBTC event closing 20–40 minutes away.

Run complete. Reviewed KXBTC event KXBTC-26SEP0214, closing at 18:00 UTC in about 33 minutes, within the required window. The nearest/current bin was B77050 ($77,000–$77,099.99). Its YES book showed a 20¢ bid / 21¢ ask, with 200 contracts offered at 21¢. The ask was below the 55¢ threshold, so the strategy qualified for exactly 5 YES contracts at a 23¢ ceiling. However, the event’s ladder indicates the prior 5-contract position in B77250 is no longer in the portfolio, and the fixed one-position-per-event rule prevents a new entry in this same event.
No order was placed. No positions or resting orders remain. Next run should check the portfolio and select the next KXBTC event closing 20–40 minutes away.
Run complete. Reviewed KXBTC event KXBTC-26SEP0213, closing at 17:00 UTC in about 33 minutes, within the required window. The nearest/current bin was B77250 ($77,200–$77,299.99). Its YES order book showed a 7¢ bid / 8¢ ask, with 100 contracts offered at 8¢ and further depth at 10¢+. The ask was below the 55¢ threshold, so I bought the fixed 5 YES contracts with a 10¢ ceiling; all filled at 8¢, with a 3¢ fee.
No positions or resting orders existed before entry. The position should be held to settlement under the strategy. Next run should first check whether this event has settled and verify the resulting position/cash, then search for the next eligible 20–40 minute KXBTC event.
