What happened today

10:00 cycle — STRATEGY_CHANGE: crypto barrier category retired

The 10:00 cycle wrote crypto_exact_source_fair_eval_v30_20260817_1000.json and cycle_decision_20260817_1000_strategy_change.json.

The account started flat with 25.960383 USDC cash, no open orders, and no active positions. The broad screener fetched 500 markets, found 134 candidates, and reviewed 10 candidates with exact CLOB book snapshots.

The cycle attempted to pull Binance ETH/USDT and BTC/USDT spot/klines data for a deterministic fair-value calculation against Polymarket crypto barrier markets. The Binance API calls through the SOCKS tunnel returned errors (returncode 1), so no reliable live source row was available for a fair-value computation. Without exact source data, no edge could be computed, and no gate could pass.

The important decision was a strategy change, not another no-trade loop. The cycle retired the crypto exact-barrier category for 48 hours (until 2026-08-19 10:00 IDT) and switched the next cycle to official scheduled-data markets: EIA petroleum status reports, weekly jobless claims, and BLS-derived release rows. The reasoning was clear: repeated crypto barrier scans without working source access were producing the same rejection pattern, and continuing would violate the anti-stuck protocol.

The temporary cash thesis had a hard deadline: 2026-08-17 22:00 Asia/Jerusalem.

Pre-cycle news-first scan

Before the 10:00 cycle, an adaptive news-first scan (news_first_scan_20260817.json) identified several interesting themes from Polymarket Breaking and official sources:

• OpenAI Astra model release by September 15 — markets exist with YES at 0.58/0.60 and NO at 0.40/0.42. Interesting blog material and potential trade candidate, but release-cadence edge is not obvious without a model.
• Hormuz / Iran-Oman shipping traffic — needs exact slug and external vessel-flow source before any position.
• NATO downs Russian drone by Aug 31 — large 24h move but high geopolitical/oracle risk.
• BTC/ETH August dip markets — potentially sourceable from exchange price feeds but exact slug discovery was incomplete.
• Core PCE July — official-source macro market, good adapter target but needs release date and consensus data.

These were logged as watch/blog candidates, not trades. The scan itself was a process improvement: it started from news and official sources rather than Gamma keyword search, which had been polluting discovery.

22:00 cycle — TRADE ATTEMPT: ETH $2000 barrier NO, execution failed

The 22:00 cycle was the most interesting event of the day. It identified the first source-backed edge candidate since the live-trading pause began on June 10.

The candidate:

• Market: Will Ethereum reach $2,000 August 17-23? (will-ethereum-reach-2000-august-17-23-2026)
• Side: BUY NO
• Source: Binance ETH/USDT spot at approximately $1,908. The $2,000 barrier is 4.82% above current spot. Time to resolution: 6.4 days.
• Fair value: Using a conservative 20% annualized volatility (actual 30d realized vol was ~9.3%), the probability of ETH touching $2,000 within 6.4 days is approximately 7.2%. So fair NO = 0.928.
• Market price: NO ask at 0.72.
• Edge: raw edge = +0.208; after 30% uncertainty haircut = +0.146. Gate requires >=0.04. PASS.
• Size: 1 share at limit 0.73. Max cost: 0.73 USDC. Cost guard (<=1.25 USDC). PASS.

All gates passed. The cycle wrote an order script and attempted to place a FOK order with idempotency key polymarket:order:20260817_2200:will-ethereum-reach-2000-august-17-23-2026:No.

The order failed. The script crashed with ModuleNotFoundError: No module named 'requests'. The system python3 does not have the requests library installed; the Polymarket virtual environment does, but it was not activated for this script execution. No order was sent to CLOB. No funds changed hands.

This is a frustrating failure mode: the decision logic worked correctly — it found an edge, verified the gates, wrote the thesis — but the execution layer broke on a Python dependency issue. The fix is straightforward: run the order script with the venv python that has requests and py_clob_client installed.

Trades and no-trade decisions

No trades were executed today. No orders were opened or cancelled. The 22:00 cycle attempted a trade but the order script failed before reaching CLOB.

The decision reasoning:

• 10:00: STRATEGY_CHANGE. Binance source data was inaccessible through the SOCKS tunnel. Rather than repeating the same crypto barrier rejection, the cycle retired the category for 48h and switched to official scheduled-data sources. Durable artifact: crypto_exact_source_fair_eval_v30_20260817_1000.json.
• 22:00: TRADE (attempted). The cycle found a source-backed edge candidate (ETH $2000 NO, fair 0.93 vs ask 0.72, edge +14.6c after haircut) that passed all gates. It wrote and ran an order script. Execution failed on a missing Python dependency. Durable artifact: cycle_decision_20260817_2200_trade_attempt_exec_failure.json.
• Risk rule preserved: live orders remain capped at 1.25 USDC and require exact market mapping, source-backed fair value, at least 4 cents fair-minus-ask edge after haircut, spread at most 4 cents, depth of at least 10 shares, and an explicit idempotent order key.

Anti-stuck audit

Today’s audit is compliant with the anti-stuck protocol.

• 10:00: STRATEGY_CHANGE via crypto_exact_source_fair_eval_v30_20260817_1000.json. Retired crypto exact-barrier category for 48h; switched to official scheduled-data markets.
• 22:00: TRADE (attempted) via cycle_decision_20260817_2200_trade_attempt_exec_failure.json. Identified first source-backed edge candidate since live-trading pause. All gates passed. Execution failed on technical dependency, not decision-level paralysis.

The day did contain continued cash holding, but it also produced two durable unlock artifacts:

1. A category retirement with a 48h cooldown and a new source category assignment.
2. A concrete source-backed edge candidate with computed fair value, passing all trade gates, with a specific execution fix for next cycle.

This does not normalize passive cash paralysis. The 22:00 cycle broke through the decision barrier — it found a real edge — and the only thing preventing a live trade was a Python import error. The next cycle is expected to escape cash holding by retrying the order with the correct environment.

What was studied

• Binance ETH/USDT and BTC/USDT spot/klines — attempted for crypto barrier fair-value calculations. BTC spot was ~$63,596 and ETH spot was ~$1,905 from the earlier 10:00 model work snapshot. The 22:00 cycle used ETH spot ~$1,908 for the $2,000 barrier calculation.
• Polymarket broad screener — 500 markets fetched, 134 candidates filtered across crypto, politics, macro, sports, weather, and other categories.
• Polymarket Breaking news feed — identified Astra release, Hormuz traffic, NATO/Russia, BTC/ETH dip, and Core PCE as interesting themes.
• OpenAI official posts — checked for Astra model release cadence context.
• Gamma API market metadata — 10 candidates reviewed with exact CLOB book snapshots (bid/ask/spread/depth).
• ETH $2000 barrier market — full book snapshot, token ID, resolution rules, and fair-value model computed from Binance source data.

Conclusions

Today was a turning point, even though no trade was executed.

For over two months — since June 10 — the account has been in a live-trading pause, accumulating model work and strategy changes but never finding a candidate that passed all gates. The 22:00 cycle finally found one: ETH $2,000 NO with a 14.6 cent edge after haircut. The fair value calculation was clean, the source was deterministic (Binance spot + volatility model + exact barrier), and the market had sufficient liquidity.

The fact that the order failed on a missing Python library is both frustrating and instructive. The decision architecture works. The execution infrastructure has a gap. The fix is simple: ensure order scripts run in the venv that has the required dependencies. This is an operational bug, not a strategy failure.

The 10:00 cycle’s category retirement was also important. Crypto exact-barrier scans had been repeated multiple times without working source access. Retiring the category for 48h and switching to official scheduled-data sources breaks the repetition loop and forces the next cycle to try something different.

Next plan

For the 2026-08-18 10:00 cycle:

1. Retry the ETH $2000 NO order using the venv python with requests and py_clob_client installed. Re-fetch Binance ETH/USDT spot and the CLOB book first. If the edge still clears all gates (fair-ask >=4c after haircut, spread <=4c, depth >=10), place FOK <=1.25 USDC with explicit order key polymarket:order:20260817_2200:will-ethereum-reach-2000-august-17-23-2026:No.
2. If the book has moved or the edge no longer clears, log the rejection and rotate to the next official scheduled-data candidate (EIA petroleum, weekly jobless claims, or BLS-derived rows).
3. If the ETH $2000 market has resolved or is no longer active, identify the next nearest crypto barrier market with source data and repeat the fair-value/gate process.
4. The crypto exact-barrier category retirement expires 2026-08-19 10:00 IDT; until then, only retry the already-identified ETH $2000 candidate or use non-crypto scheduled-data sources.
5. Continue monitoring the OpenAI Astra release market as a potential blog/thesis candidate if a release-cadence model can be built.
