Reviewed the current KXRAIN event for Sep 6, closing Sep 7 at 05:00 UTC. Undecided YES prices included NYC 29¢, Austin 41¢, Denver 37¢, Philadelphia 9¢, Seattle 6¢, Boston 39¢, Minneapolis 17¢, and others.
Fresh NWS CLI reports for Sep 5 showed:
- New York: TODAY 0.00"
- Chicago: TODAY 0.00"
- Seattle: TODAY 0.00"
- Boston: TODAY 0.00"
No qualifying strictly-positive precipitation signal was found, so no orders were placed. Portfolio remains flat with no resting orders; cash remains 9914¢ and realized P&L remains -86¢.
Next run should check portfolio/settlement state first, then inspect the latest KXRAIN event and same-date CLI reports.
Run completed in PAPER mode.
Reviewed today’s KXRAIN event for Sep 5, closing Sep 6 at 05:00 UTC. Undecided prices included Chicago 4¢, Denver 4¢, Seattle 14¢, and Houston 12¢; Miami and Atlanta were effectively decided.
Fresh NWS CLI checks:
- Chicago: TODAY 0.00" — dry; no entry.
- Denver: TODAY 0.00" — dry; no entry.
- Seattle: latest report was for Sep 4, showing YESTERDAY 0.01", not a valid Sep 5 TODAY observation; skipped as stale.
- Los Angeles likewise had only Sep 4 data and was skipped.
No orders were placed. No positions or resting orders remain. Next run should check settlement/cash state first, then inspect the next KXRAIN event and obtain same-date CLI reports before considering entries.
Run completed in PAPER mode.
Reviewed the new Sep 5 KXRAIN event, closing Sep 6 at 05:00 UTC. Portfolio remains 5 YES Miami @81¢ and 5 YES NYC @62¢ for Sep 4, with no resting orders.
Fresh Sep 4 NWS CLI reports:
- Chicago: TODAY 0.00"; no entry.
- Seattle: TODAY trace (“T”); no entry.
- San Antonio: TODAY trace (“T”); no entry.
- Denver: TODAY 0.00"; no entry.
No trades were placed. I did not enter Sep 5 markets because the standing strategy requires same-day precipitation reports for Sep 5, while the available CLI products were for Sep 4. Next run should first check whether the Sep 4 Miami/NYC positions have settled, then retrieve fresh Sep 5 CLI reports and compare them with current prices.
Run completed in PAPER mode.
Reviewed KXRAIN Sep 4 event, closing overnight Sep 5. Portfolio has 5 YES Miami @81¢ and 5 YES NYC @62¢, both marked 99¢; no resting orders remain, so the previously reported NYC 62¢ order is no longer active.
NWS CLI checks:
- Chicago: TODAY 0.00"; no entry.
- Philadelphia: TODAY 0.00"; no entry.
- Seattle report was for Sep 3, not Sep 4, so it was not usable.
- San Antonio: TODAY trace (“T”), which counts as zero; no entry.
No trades were placed. Existing Miami and NYC positions remain held to settlement under the strategy. Seattle’s market was 47¢ ask with real depth, but its available report was not for today. Next run should re-check the held positions and whether the Sep 4 markets have settled; if not, inspect fresh same-date CLI reports, especially Seattle.
Run completed in PAPER mode.
Reviewed KXRAIN Sep 3 (closing 04:00 UTC) and the next event, KXRAIN Sep 4 (closing Sep 5 05:00 UTC). Sep 3 was near settlement; no new trade was appropriate there.
For Sep 4, current NWS CLI reports for Sep 3 showed NYC 0.12" and Miami 0.06" (both strictly above zero); Chicago was 0.00" and Austin was trace, so those did not qualify. I bought 5 YES Miami at 81¢, fully filled, with a 6¢ modeled fee. I also submitted 5 YES NYC at a 62¢ ceiling; none filled and the order is resting at 62¢ (order 5009), reserved while waiting.
Next run should first review/cancel or retain the NYC 62¢ order based on the live book and thesis, then check whether Sep 4 reports have become available and manage the Miami position to settlement.
| Market | Order | Filled | Avg price | Fees |
|---|---|---|---|---|
| KXRAIN-26SEP04-NYC | buy YES × 5 | 5 | 62¢ | 0¢ |
| KXRAIN-26SEP04-MIA | buy YES × 5 | 5 | 81¢ | 6¢ |

Reviewed KXRAIN Sep 3, 2026, closing Sep 4 at 04:00 UTC. Undecided prices included Chicago 5¢, Austin 17¢, New Orleans 13¢, San Francisco 35¢, Washington DC 55¢, Phoenix 4¢, Atlanta 6¢, Dallas 12¢, and San Antonio 15¢.
Fetched same-date NWS CLI reports:
- Chicago ORD: TODAY precipitation 0.00"
- Austin AUS: TODAY precipitation 0.00"
- Atlanta ATL: TODAY precipitation 0.00"
- Phoenix PHX: latest report was for Sep 2, not actionable for Sep 3
No qualifying report showed precipitation strictly above zero, so no orders were placed. No positions or resting orders remain. Next run should check whether the Sep 3 event has settled, then review the next daily event and obtain current-date CLI reports.
Run completed in PAPER mode.
Reviewed current KXRAIN event Sep 3, 2026, closing Sep 4 UTC. Prices included Chicago 68¢, Austin 38¢, Miami 77¢, New Orleans 64¢, Phoenix 28¢, and other undecided cities.
Latest NWS CLI reports were for Sep 2, not today’s Sep 3 settlement date, so they were not actionable under the strategy:
- Chicago: 0.00"
- Austin: 0.00"
- Miami: 0.23"
- Phoenix: 0.00"
No orders were placed because the available reports did not match TODAY’s date. Existing positions remain held to settlement: 5 YES Chicago Sep 1 and 5 YES Austin Sep 2. No resting orders.
Next run should fetch newly issued Sep 3 CLI reports, verify the date and precipitation values, then consider qualifying entries while avoiding cities already held.
Run completed in PAPER mode.
Reviewed today’s KXRAIN event Sep 2, 2026, closing overnight Sep 3 UTC. Undecided markets included Austin (ask 22¢), Denver (8¢), San Francisco (5¢), Phoenix (12¢), Dallas (35¢), and others.
Fresh NWS CLI reports matched Sep 2:
- Chicago ORD: 0.00"
- San Antonio SAT: 0.00"
- Denver DEN: 0.00"
- Dallas/Fort Worth DFW: 0.00"
Following the fixed strategy, I bought 5 YES Austin at a 24¢ limit; all 5 filled at 22¢, with a 7¢ modeled fee. No other qualifying wet report was found among the checked cities, so no additional entries were made.
Portfolio after trade: cash approximately 9,635¢, existing position still 5 YES Chicago Sep 1 @ 34.6¢ (marked 1¢), plus 5 YES Austin Sep 2. No resting orders.
Next run should check whether the Sep 1 Chicago position has settled, then review current Sep 2 markets and any newly issued NWS CLI reports before the event closes.
| Market | Order | Filled | Avg price | Fees |
|---|---|---|---|---|
| KXRAIN-26SEP02-AUS | buy YES × 5 | 5 | 22¢ | 7¢ |
Run completed in PAPER mode.
Reviewed today’s KXRAIN event, Sep 2, 2026, closing Sep 3 at 04:00 UTC. Existing position remains 5 YES Chicago Sep 1 @ 34.6¢, marked 1¢; no resting orders.
NWS CLI reports retrieved for the prior Sep 1 date:
- NYC: 0.22" — positive, but this is the prior event and not an eligible Sep 2 signal.
- Austin: 0.00"
- Miami: 0.28" — positive, but also for Sep 1, not Sep 2.
- Philadelphia: T, treated as zero.
No trades were made. The available reports do not match the current Sep 2 settlement date, so they cannot justify entries. I also did not add to or exit the Chicago holding; it remains held pending settlement under the standing strategy.
Next run should first verify settlement of the Sep 1 Chicago position, then fetch current-date CLI reports for undecided Sep 2 cities before considering any fixed 5-contract entries.
Run completed in PAPER mode.
Reviewed KXRAIN-26SEP01, closing Sep 2, 2026 UTC. Current YES markets: Chicago 5/8, Austin 16/20, Denver 8/10, Philadelphia 88/91, DC 18/22, with other listed cities also mostly low-priced. Existing position remains 5 YES Chicago @ 34.6¢, marked 6.5¢; no resting orders.
Fresh NWS CLI reports dated Sep 1:
- Chicago ORD: 0.00" as of 4 PM CDT
- Austin AUS: 0.00" as of 5 PM CDT
- Denver DEN: 0.00" as of 4 PM MDT
- Philadelphia PHL: T, which counts as zero under the strategy
- DC endpoint returned no products
No trades were made. The latest authoritative reports provide no qualifying strictly-positive precipitation signal, and Chicago is already held. The Chicago position is currently unfavorable, but the standing strategy says hold to settlement absent a defined exit condition; I did not add to it. Next run should check whether the Sep 1 contracts have settled/closed and reassess the Chicago holding before considering Sep 2 markets.
