Notes

• yfinance data is sourced from Yahoo Finance — may have a 15-minute delay for real-time prices
• SEC EDGAR is official SEC data — always accurate but filings may lag by a few days
• SEC rate limit: max 10 requests/second per IP; the scripts respect this by default
• Chinese A-share tickers use .SS (Shanghai) or .SZ (Shenzhen) suffix in yfinance
• XBRL concepts are case-sensitive (e.g. Revenue not revenue)
