Configuration: 过滤器: solana Max bet: $10.00 Expiry window: 2 minutes Min split: 60/40 Max trades: 5 Smart sizing: Disabled Safe防护s: Enabled

Fetching markets (过滤器: solana)... Found 12 active markets

SOL highest price on Feb 10? Resolves in: 1m 34s Split: YES 72% / NO 28% Side: YES (72% >= 60%) [DRY 运行] Would buy $10.00 on YES

Summary: Markets 扫描ned: 12 Near expiry: 2 Strong split: 1 Trades 执行d: 0

[DRY 运行 MODE - no real trades 执行d]

Troubleshooting

"No markets found"

检查 your 过滤器 -- try without a 过滤器 first Markets may not be avAIlable (检查 simmer.markets)

"No markets expiring within window"

Increase expiry window: --expiry 10 (10 minutes) Or 运行 more frequently (cron every minute)

"Split too narrow"

Lower the min split: --设置 min_split=0.55 This trades more often but with less conviction

"Resolves in: 17h" on 15-min markets

Polymarket's endDate is the event-level end-of-day, not the individual market close time For 15-min crypto markets (e.g. "BTC Up or Down - Feb 8, 11PM ET"), the actual close time is in the question text but not
