❌ Negative Example (Forbidden Output)

• Fetch BTC/ETH data from exchanges other than Binance (Huobi/OKX etc.)
• Only output price without volume, liquidity, or other strategy-required data
• Use expired K-line data with delay over 1 minute

5. Boundary Definition

Forbidden Operations

1. Do NOT call Binance trading API for entry/settlement — only data fetch and verification
2. Do NOT fetch data of pairs other than BTC/ETH
3. Do NOT store user account privacy data

Exception Handling

1. When Binance API is under maintenance or rate limit → push alert immediately, stop invalid fetch, auto-restart after API recovery
2. Do NOT output invalid data to signal calculation module if data verification failed

Fallback Strategy

If fetch fails 3 times consecutively → push "Data Fetch Exception" alert immediately, pause signal generation until data returns to normal, avoid false signal caused by wrong data
