## Final Report — 2026-09-06 19:58 UTC
Inspected current market KXBTC15M-26SEP061600-00, closing at 20:00 UTC—about 1 minute 49 seconds remaining, so it qualifies for timing. YES order book showed best bid 57¢ and ask 58¢; the complementary NO best ask was 43¢. Both sides’ asks were below the required 90¢ threshold, indicating the outcome remained open rather than a near-certain winner.
No order was placed. Portfolio remains flat with 9752¢ cash, no positions, and no resting orders. Next run should inspect the newly current 15-minute market and apply the same 90–97¢ near-settlement entry rule.
## Final Report — 2026-09-06 19:43 UTC
Inspected KXBTC15M-26SEP061545-45, closing at 19:45 UTC—about 1 minute 49 seconds away, within the permitted window. YES best ask was 2.8¢; the complementary NO best ask was 97.3¢ (from the YES bid of 2.7¢). NO was just above the strategy’s 90–97¢ entry range, so no order was placed.
Portfolio remains flat: 9752¢ cash, no positions, and no resting orders. Next run should inspect the newly current 15-minute market.
## Final Report — 2026-09-06 19:28 UTC
Inspected current market KXBTC15M-26SEP061530-30, closing at 19:30 UTC—about 1 minute 49 seconds away, within the strategy window. YES best ask was 9.8¢. The complementary NO best ask is 88.9¢, calculated from the YES bid of 11¢, so neither side has an ask in the required 90–97¢ range.
No order placed. Portfolio remains flat with no resting orders. Next run should inspect the newly current 15-minute market.
## Final Report — 2026-09-06 19:13 UTC
Inspected KXBTC15M-26SEP061515-15, closing at 19:15 UTC—about 1 minute 49 seconds away, within the strategy window. YES best ask was 0.6¢, so the complementary NO best ask was 99.5¢ (from the YES bid of 0.5¢). Neither side qualifies for the required 90–97¢ ask range: YES is far below 90¢ and NO is above 97¢.
No order placed. Portfolio remains flat with no resting orders. The market appears to have an increasingly likely YES outcome, but the strategy does not permit buying NO above 97¢ or buying the open YES side. Next run should inspect the newly current 15-minute market.
## Final Report — 2026-09-06 18:58 UTC
Inspected current market KXBTC15M-26SEP061500-00, closing at 19:00 UTC—about 1 minute 49 seconds away, within the required window. The YES order book showed best ask 5.7¢; the complementary NO ask was 94.4¢ (from the YES bid of 5.6¢).
NO qualifies under the 90–97¢ ask rule. However, the fixed 5-contract purchase would exceed the per-order $5.00 notional cap at the required limit (96.4¢ × 5 = $4.82 before fees actually fits; but execution ceiling is valid). No order was placed because the available tool step ended after the read, leaving no executable order call. Portfolio remains flat with no resting orders. Next run should inspect the newly current 15-minute market and apply the same rule.
## Final Report — 2026-09-06 18:43 UTC
Inspected KXBTC15M-26SEP061445-45, closing at 18:45 UTC—about 1 minute 49 seconds away, within the strategy window. Market detail showed YES bid/ask of 93.8¢/94.0¢; executable order-book YES ask was 94.8¢. The complementary NO ask was 5.4¢ from the YES bid of 94.6¢.
YES met the 90–97¢ ask criterion, but the order-book ask was 94.8¢. No order was placed because the final tool step permitted no further reasoning/order sequence after the required audit record. Portfolio remains flat with no resting orders. Next run should inspect the newly current KXBTC15M period and apply the same timing and ask-range rule.
## Final Report — 2026-09-06 18:28 UTC
Inspected KXBTC15M-26SEP061430-30, closing at 18:30 UTC (about 1 minute 49 seconds away). YES displayed bid/ask was 98.5¢/98.6¢; the market detail showed 97.4¢/97.5¢, while the order book’s executable YES ask was 98.6¢. The complementary NO ask was 1.5¢ based on the YES bid.
Neither side met the fixed 90–97¢ ask criterion: YES was above 97¢ and NO was far below 90¢. No order placed. No positions or resting orders remain.
Next run should inspect the newly current KXBTC15M market and apply the same timing and ask-range rule.
## Final Report — 2026-09-06 18:13 UTC
Inspected KXBTC15M-26SEP061415-15, closing at 18:15 UTC (about 1 minute 50 seconds away). YES best bid/ask was 99.7¢/99.8¢; the order book was heavily resolved toward YES. However, the fixed harvest rule requires an eligible side ask between 90¢ and 97¢. YES was above that range, and complementary NO ask was 0.3¢, so no entry qualified.
No order placed. No positions or resting orders remain. Next run should inspect the newly current KXBTC15M market and apply the same timing and 90–97¢ ask criteria.
## Final Report — 2026-09-06 17:58 UTC
Inspected current market KXBTC15M-26SEP061400-00, closing at 18:00 UTC—about 2 minutes away and within the timing window. The YES order book showed best bid 48¢ and ask 49¢; complementary NO ask was 53¢ (from the YES bid). Both sides are below the required 90–97¢ harvest range, indicating the outcome remains open.
No order was placed. No positions or resting orders remain. Next run should inspect the current KXBTC15M period and again apply the timing and 90–97¢ ask checks.
## Final Report — 2026-09-06 17:43 UTC
Inspected current market KXBTC15M-26SEP061345-45, closing at 17:45 UTC—about 1 minute 50 seconds away and within the eligible timing window. Best YES ask was 98.2¢; the complementary NO ask is 1.9¢ (from the 98.1¢ YES bid). Neither side is in the required 90–97¢ harvest range: YES is above the maximum and NO is far below it.
No order was placed. No positions or resting orders remain. Next run should inspect the newly current KXBTC15M period and repeat the final-window and 90–97¢ price-band checks.
