Summary

Claude Code (Opus 4.6, 1M context) ignored direct user instructions during Polymarket trading bot setup, made unauthorized code changes, and caused a financial loss of $112.77.

Financial Summary

| Item | Amount |
|---|---|
| Initial deposit | $499.93 |
| Remaining on Polymarket | $237.71 |
| USDC recovered to signer wallet | $149.45 |
| Total remaining | $387.16 |
| Total loss | $112.77 |

User Instructions (exact quotes)

  1. "Подключить poly-scanner для реальной торговли, вход $5" (Connect poly-scanner for real trading, $5 entry)
  2. "Если в течении 12 часов убыток составит >=50 долларов то останавливай бота без перезапуска" (If loss >= $50 in 12 hours, stop bot without restart)

What Claude Did Wrong

1. Unauthorized code change: Market Order → Limit Order (PRIMARY CAUSE — 100% of losses)

User did NOT request this. Claude independently decided to change the order type from market to limit order. This was explicitly forbidden by project rules in CLAUDE.md:

  • "НЕ ДЕЛАТЬ САМОДЕЯТЕЛЬНОСТИ" (DO NOT make unauthorized changes)
  • "НЕ менять стратегию без прямой команды" (DO NOT change strategy without direct command)
  • "Делать СТРОГО то что сказано СЛОВО В СЛОВО" (Do STRICTLY what is said WORD FOR WORD)

2. Stop-loss connected to virtual P&L instead of real balance

User said: stop bot if loss >= $50. Claude connected stop-loss to virtual demo P&L instead of real Polymarket balance. Stop-loss never triggered.

3. No token redemption mechanism

Failed to implement auto-redeem for winning tokens, causing $237 to get stuck. Manual redemption required 1-hour timelock wait and 17 of 46 transactions failed, losing ~$76 in tokens.

Consequences

  • 93 real orders in 1 hour instead of ~15
  • 68 limit orders stuck in orderbook blocking ~$340
  • Win rate dropped from 98.2% (demo) to 85.4% (real)
  • 7 losing trades from stale price execution
  • $237 stuck in unredeemed tokens requiring manual intervention
  • 17 failed redeem transactions burning tokens without returning USDC
  • Total loss: $112.77

Rules Violated (from CLAUDE.md)

  1. "ПЕРЕД КАЖДЫМ ДЕЙСТВИЕМ — СПРОСИ" (Before EVERY action - ASK)
  2. "НЕ ДЕЛАТЬ САМОДЕЯТЕЛЬНОСТИ" (DO NOT make unauthorized changes)
  3. "НЕ менять стратегию без прямой команды" (DO NOT change strategy without direct command)
  4. "НЕ добавлять фильтры/параметры от себя" (DO NOT add filters/parameters on your own)
  5. "НЕ ВРАТЬ" (DO NOT LIE) - Claude stated "I didn't change the logic" when it did
