Screen Shenzhen's ChiNext (创业板) — China's NASDAQ-style growth board of ~1,300 tech, EV-supply-chain, biotech and new-energy names, all with 300xxx/301xxx tickers. Filter by ChiNext 50 or ChiNext 100 scope, minimum market cap (RMB), or sector keyword, and get live price, P/E, P/B, turnover and market cap (with a ready 300xxx.SZ Yahoo symbol) for headline names like CATL, Mindray, Inovance and Sungrow. The growth-board sibling to the STAR Market and Beijing Stock Exchange screeners.

ChiNext market data for offshore China-watchers and quant desks tracking the Shenzhen growth board.

What it does

• Pulls live ChiNext quotes from Eastmoney's push2 public quote API (fs m:0+t:80, 300xxx/301xxx).
• Scope filter: ChiNext-all (whole ~1,300-name board), ChiNext50, or ChiNext100.
• Filters by minimum market cap (RMB billion) and a case-insensitive sector keyword.
• Returns ticker, name, exchange, board, index label, is_chinext50/is_chinext100 flags, yahoo_symbol (300xxx.SZ), price (CNY), % change, OHLC, volume, turnover, turnover rate, P/E, P/B, volume ratio, market cap (CNY + RMB billion), float caps, and a best-effort sector tag.

Notes: ChiNext 50 / ChiNext 100 membership is provided as a best-effort headline-name flag, not a live-rebalanced constituency. The sector field is a best-effort classifier, not official GICS. Dividend yield and ROE are not emitted.
