#### Error Code Analysis

| Error Code / Message                                         | Reason                                                                                                    | Solution                                                                                                  |
| ------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------- |
| **Admin code = 1004** `chain network error`                  | <p><strong>Chain Network Congestion.</strong><br>Usually due to unstable RPC nodes.</p>                   | This is temporary. The Bot will retry automatically. Wait a moment.                                       |
| **fail to place order** `insufficient balance` / `allowance` | <p><strong>Low Balance or Allowance.</strong><br>Not enough USDC to buy, or not enough MATIC for Gas.</p> | <p>1. Check USDC balance.<br>2. Ensure you have small amount of MATIC (POL).<br>3. Deposit and retry.</p> |
| **fail to sell position** `reason: no match`                 | <p><strong>Low Liquidity.</strong><br>Polymarket order book is thin; no buyers at your price.</p>         | Not a Bot error. It's a market issue. Retry later or adjust your sell price.                              |
| <p><strong>contract call failed</strong><br>(Withdrawal)</p> | **Network Fluctuation or Gas Estimation Error.**                                                          | Try restarting the Bot (`/start`) and withdraw again. If it fails repeatedly, contact support.            |

#### Status Issues

<details>

<summary>Q: Why did copy notifications stop suddenly?</summary>

A: Please check:

1. Did the Bot stop running? (Send `/start` to wake it up).
2. Did you accidentally block the Bot in Telegram settings?
3. Has the target trader actually made any trades recently?

<summary>Q: The event ended, why haven't I received my winnings?</summary>

A: This is a **Polymarket Platform** process.

* After market resolution, there is a delay in settlement. Please wait patiently for the platform to distribute funds.
