China A-Share Smart-Money Tracker — Institutional Score & Cost

See what institutions are doing in every Chinese A-share in one run. For each stock this Actor returns Eastmoney's institutional-behavior signals: an institutional score (0–100), institutional participation %, the "main-force" (smart-money) average cost basis versus the current price, super-large / large order net inflow, an attention score and the popularity rank. No login, no account, no API key.

The standout field is priceVsMainForceCostPct — how far the current price sits above or below the average cost of the dominant ("main force") money in the stock. Below cost, smart money is underwater; well above, it's sitting on gains. Combined with the institutional score and participation, it's a fast read on positioning that Chinese traders watch closely (主力成本 / 机构参与度).

• Min institutional score (minScore) — e.g. 70 to surface only heavily-institutional names.
• Stock codes (securityCodes) — restrict to specific tickers, or leave empty for the whole market.
• Include NEEQ (includeNEEQ) — off by default; A-shares only.
• Max stocks (maxResults).

Use cases

• Smart-money screening — sort by institutionalScore (or filter minScore) to find the most institutionally-active names.
• Cost-basis edge — rank by priceVsMainForceCostPct to find stocks trading near/below where the main force got in.
• Flow confirmation — combine superLargeNetInflowCny + superBuyRatioPct to see where big money is buying.
• Watchlist monitoring — set securityCodes to track institutional behavior on stocks you hold.
• Dashboards / models — feed daily institutional signals into your own app or BI tool.

Tips

• Run on a schedule (daily after close) and append to one dataset to build an institutional-behavior time series.
• priceVsMainForceCostPct crossing from negative to positive can mark a shift in main-force positioning.
• Mix minScore with sortBy: "super_inflow" to find high-quality names also seeing big-order buying.
