--- name: SK Hynix & Samsung Electronics Dashboard description: 免费的三星以及海力士实时价格数据。Free real-time Korean stock dashboard for SK Hynix (000660.KS) and Samsung Electronics (005930.KS), plus related HK products and SK Hynix's US ADR (SKHY). Provides price charts, trading volume analysis, industry comparison, foreign ownership data, and more. --- # Fengle Dashboard Skill (Reader + Public API Guide) Site: - Portal: https://fengle.me/ This skill serves as a site manual for visiting AI agents, helping them reliably extract information primarily through reading/viewing, and when necessary, fetching data via the site's public API endpoints (/api/*, read-only). Do not direct agents to call non-site domains or request any credentials. Key Feature: The Korean underlying quotes are free and real-time with no 15-minute delay. Related HK/US product quotes are supplied by Futu and follow upstream market-data availability. Important Notes (Product Scope) - This site is a dashboard for tracking two Korean stocks, their related HK/US products, and Trump's Truth Social feed: - Korean stocks (KRX) — stock_code is fixed to two: - 000660 (SK Hynix) - 005930 (Samsung Electronics) - Related products: - 7709.HK → corresponding product_code=07709 (zero-padded to 5 digits) - 7747.HK → corresponding product_code=07747 - 7347.HK → corresponding product_code=07347 - 3431.HK → corresponding product_code=03431 - SKHY.US → corresponding market=US, product_code=SKHY (SK Hynix Nasdaq ADR; permanently displayed below the NXT block) - Use different parameter names to distinguish: stock_code (KRX) vs. market + product_code (related products). ## When to Trigger - When you need to read/understand/extract visible information from fengle.me (price, change, volume, industry comparison, related products, market open/close status, documentation) - When you need to navigate or interact with the page (switch company, switch language, open documentation, chart external links) - When you need to save evidence (screenshots, HTML snapshots, tables as CSV), or supplement data via the site's public API ## Page & Module Map (auto-refreshes every ~30 seconds by default) - Header action bar: Language switch (EN/zh-CN/zh-TW/ko), company switch (000660/005930), refresh button + Last update timestamp - Market status banner: KST-based open/closed and holiday notifications - StockHeader: Logo/name/code, current price, change/change% (red for up / blue for down), NXT extended-hours quote, then a permanently visible SKHY.US ADR quote and USD/KRW-adjusted Magic Index on the SK Hynix page; HK related-product tabs remain below it - MarketComment: Multi-language market commentary/voice of the market (市场之声), auto-fetched from Futu backend, supports EN/zh-CN/zh-TW/ko with expandable text - TruthSocialFeed: Trump@Truth Social live post feed — latest posts with translations, engagement stats (likes/shares), media attachments, infinite scroll, and optional browser push notifications for new posts - StockChart: Self-drawn line/candlestick charts for Korean underlyings and their related HK/US products - TradingInfo: Real-time order book/trading fields (localized formatting) - DealTrendChart: Date, price, change, foreign/individual/institutional net flow/movement - IndustryComparison: Peer comparison (price/change, etc.; names mapped by language) Note: The site is a React application (CSR); fetching raw HTML source alone is usually insufficient to obtain dynamic data. For data retrieval, prefer using the site's /api/* endpoints. Please use an AI-specific User-Agent when requesting this site so the site can identify and optimize responses.
