Recent runs
Run 2026-09-04 19:35Z — Reviewed KXINXU-26SEP04H1600, closing 20:00Z (25 minutes away). The nearest-at-money strike was 7,715 or above. Minute YES prices were volatile: 35¢ → 50¢ → 57¢, then declined to 47–50¢ over the latest minutes. Although there was an earlier qualifying move, the latest direction is not sufficiently clear, so the late-momentum entry condition is not met.
Current book: YES bid 48¢ / ask 51¢, with ample displayed depth; the executable ask is within range, but no trade was placed. Portfolio remains flat with no resting orders. Next run should check this event’s settlement status or the next eligible hourly event, along with any new qualifying 3–5 minute move.
Run 2026-09-04 18:35Z — Reviewed KXINXU-26SEP04H1500, closing 19:00Z. The nearest-at-money strike was 7,715 or above. YES minute prices rose from 46¢ at 18:33 to 57¢ at 18:34 and 58¢ at 18:35, a qualifying upward move. The YES ask was 56¢, within the 30–80¢ range, with displayed depth.
Bought 5 YES contracts with a 59¢ limit; all filled at 56¢. Fee was 9¢. No resting orders remain. Hold to settlement at 19:00Z. Next run should check settlement and position resolution first.

Run 2026-09-04 17:35Z — Reviewed KXINXU-26SEP04H1400, closing 18:00Z. The near-ATM strike was 7,715 or above. YES prices fell sharply from 72¢ at 17:24 to 30¢ at 17:31, then 25¢ and 28¢; this satisfies the ≥5-point downward momentum signal. The NO ask was 71¢, within the required 30–80¢ range, with ample displayed depth.
Bought 5 NO contracts with a 74¢ limit; all filled at 71¢, with an 8¢ fee. No resting orders remain. Hold to settlement at 18:00Z. Next run should check settlement and position resolution first.

Run 2026-09-04 16:35Z — Reviewed KXINXU-26SEP04H1300, closing 17:00Z. The at-the-money strike was 7,725 or above. YES minute prices moved from 49¢ at 16:25 to 38¢, 37¢, 36¢, 29¢, then rebounded to 34¢, 45¢, 43¢, and 46¢. Despite the rebound, the recent sequence met the ≥5-point downward momentum signal; the NO ask was 55¢, within the 30–80¢ range. Depth was ample.
Bought 5 NO contracts with a 58¢ limit; all filled at 55¢, with a 9¢ fee. No resting orders remain. Hold the position to settlement at 17:00Z. Next run should check settlement and position resolution first.

Run 2026-09-04 15:35Z — Reviewed KXINXU-26SEP04H1200, closing 16:00Z. The at-the-money strike was 7,710 or above. YES minute prices fell sharply from 53¢ at 15:30 to 36¢, 29¢, then 35¢, meeting the ≥5-point downward momentum signal. The NO ask was 52¢ (YES bid 48¢), within the required 30–80¢ range; order-book depth was sufficient.
Bought 5 NO contracts with a 61¢ limit; all filled at 52¢, with a 9¢ fee. No resting orders remain. The 5-contract NO position should be held to settlement. Next run should check this position and settlement status first.

Run 2026-09-04 14:35Z — Reviewed KXINXU-26SEP04H1100, closing at 15:00Z. The nearest-at-money strike was 7,725 or above, with YES bid/ask 50¢/53¢.
Recent YES minute prices were highly volatile: 49, 56, 60, 56, 50, 61, 49, 48, 50, 63, 52, 47, 54, 46, 43. The latest 3–5 minutes declined from 54¢ to 43¢, satisfying the directional momentum threshold for buying NO. However, the NO ask is based on the YES bid: 100−51 = 49¢, within the 30–80¢ range. Order-book depth supports execution.
Bought 5 NO contracts at a 52¢ limit (3¢ above the observed 49¢ NO ask); this is a marketable entry with a maximum notional of $2.60. Position should be held to the 15:00Z settlement under the strategy. Next run should check settlement/position status first.
Run 2026-09-03 19:35Z — reviewed KXINXU-26SEP03H1600, closing at 20:00Z. The nearest-at-money strike was 7,750 or above, currently YES bid/ask 49¢/53¢. Recent YES prices were volatile: 57, 53, 54, 49, 40, 45, 42, 49, 47, 57, 56, 60, 56, 51, 50. Although there was a rebound from 40¢, the latest 3–5 minutes declined from 60¢ to 50¢ and did not show a qualifying sustained 5+ point directional move under the strategy rule.
No order placed. Cash remains 10510¢; no positions or resting orders. Next run should inspect the next eligible hourly KXINXU event and its nearest-at-money momentum.
Run 2026-09-03 18:35Z — reviewed KXINXU-26SEP03H1500, closing at 19:00Z with 25 minutes remaining. The at-the-money strike was 7,755 or above. YES history was volatile rather than showing a qualifying directional move: 40¢, 39¢, 43¢, 32¢, 39¢, 45¢, then 48¢. Although the latest move was upward, it did not establish a clear sustained 5+ point momentum signal over the required recent window.
The current YES ask was 46¢, with substantial depth, but the strategy signal requirement was not met. No order placed. No positions or resting orders remain. Next run should first check the portfolio settlement result, then inspect the next eligible KXINXU hourly event and its nearest-at-money momentum.
Run 2026-09-03 17:35Z — reviewed KXINXU-26SEP03H1400, settling at 18:00Z with 25 minutes remaining. The nearest-at-money strike was 7,745 or above. YES momentum was strongly upward: 16¢ at 17:23, then 32¢, 42¢, 47¢, and 52¢ by 17:34. The current YES ask was 54¢, with substantial displayed depth, so the move met the required fresh 5+ point directional signal and the executable price was within 30–80¢.
Bought 5 YES at a 55¢ limit; all 5 filled at 55¢, with a 9¢ fee. No resting orders remain. Position should be held to settlement under the strategy. Next run should first check whether this market settled and confirm the resulting portfolio, then inspect the next eligible hourly event if applicable.

Run 2026-09-03 16:35Z — reviewed KXINXU-26SEP03H1300, closing at 17:00Z with 25 minutes remaining.
The nearest-at-money strike was 7,745 or above (KXINXU-26SEP03H1300-T7744.9999). Recent YES prices were volatile: 31¢ → 25¢ → 19¢, then 26¢ → 19¢ → 18¢ → 19¢ → 26¢ → 25¢ → 26¢. Although the latest move rebounded 7–8 points from the 18–19¢ lows, it is not a clean sustained directional move and the current YES ask is 36¢ while the corresponding NO buy would be 65¢. The signal is choppy and below the strategy’s required fresh, unreversed momentum standard.
No trade placed. No positions or resting orders remain. Next run should inspect the then-nearest eligible KXINXU hourly event and again require a clean 5+ point move over the latest 3–5 active minutes.
