Read 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 from 0 to 100, institutional participation percentage, the "main-force" (smart-money) average cost basis at 1/20/60 days versus the current close, super-large and large-order net inflow in CNY, an attention score and the popularity rank. The standout column is priceVsMainForceCostPct — how far price sits above or below where the dominant money got in — a positioning read Chinese traders watch closely (主力成本 / 机构参与度). No login required.

Each run returns the latest trading-day snapshot of the whole market (one row per stock), so you can rank and screen the A-share universe on institutional behavior in seconds.

What you get

One row per stock (latest trading day):

Input

• Sort by (sortBy) — score / participation / attention / change / super-large net inflow.
• 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) — default 100.

Example input

{"sortBy":"score","minScore":70,"maxResults":100}

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 the latest institutional signals into your own app or BI tool.

Tips

• Each run is the latest snapshot. To build a history, schedule it daily after close and append each run to one dataset — the Actor itself does not return past days.
• 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.

FAQ

Do I need an account or API key? No — live from Eastmoney's public dataset.

Which markets are covered? All A-shares (Shanghai & Shenzhen main, STAR, ChiNext, BSE). NEEQ optional.

How current is it? Each run returns the latest trading-day snapshot, published by Eastmoney after the session.

Is there a history mode? No — the Actor returns only the latest snapshot per run. Schedule it daily and append to one dataset to build your own time series.

What are "main-force" and "super-large orders"? Main force (主力) = the dominant institutional/large money; super-large orders are the biggest trade tranches — a common proxy for institutional activity.
