Nombres y descripciones de las herramientas tal como los informó el servidor el 10 nov 2026. Los escribió el creador, no nosotros; los mostramos como texto sin formato.
get_tickerGet real-time price snapshots for one or more symbols. Returns symbol, last_price and millisecond timestamp. Other fields are conditional, including open, prev_close, category, traded value and US extended-hours quotes. Crypto statistics use a rolling 24h window; traditional mark
get_klineGet historical OHLCV candles, including CN/HK futures open_interest. The last candle may still be forming. Adjusted history may change after corporate actions; record query time and adjustment mode for backtests. Futures normally omit quote_volume. Limit defaults to 100, caps at
get_kline_latestGet the most recent (live/incomplete) K-line candle for one or more symbols.
get_order_bookGet order book (market depth) with bid and ask price levels. Returns bids/asks as [price, quantity] arrays, best price first; timestamp in ms. Depth is market-defined: US 1, HK 10, CN 5, CN futures 1, HK futures 10, crypto up to 1000 levels per side. Actual depth may be lower; no
get_recent_tradesGet the most recent executed trades for a symbol. Returns trade id, price, quantity, side (buy/sell/neutral), and timestamp in ms. Futures may also return open_interest_change and position_effect (long_open, short_open, both_open, long_close, short_close, both_close, long_transfe
get_available_symbolsQuery supported trading symbols with pagination. Use this to discover and verify codes before other calls. Query CN or HK with type=futures for futures, e.g. BU2609 or HSI8888. Follow pagination.total; market is case-insensitive. Product counts change over time.
get_ex_factorsGet stock adjustment factors at data.data.{symbol} in the response envelope. Each event has forward/backward factors: adjusted = raw * factor_a + factor_b. Forward: apply factors after the candle timestamp oldest first. Backward: apply factors at/before the timestamp newest first

get_capital_flowGet capital flow (money flow) analysis for a stock. Returns intraday flow timeline and breakdown of capital inflows/outflows by order size: large, medium, and small. All timestamps in this response are Unix seconds, unlike the millisecond timestamps in most market tools. Supporte
get_company_profileGet the current company profile, including listing and industry information.
get_company_executivesGet the current company executives, directors, and key personnel.
get_financials_latestGet field-level financial rows for up to 20 periods; n counts periods, not rows. Use one kind per call. Field names and display names are included in rows.
get_financials_annualGet annual financial metric rows; n counts fiscal years, not rows. period_type is normally af, but fiscal year-end data may use q4.

get_buybackGet company buyback plans, executions, and related events.
get_shareholders_latestGet the latest disclosed shareholder structure snapshot. The report date identifies the disclosure period, not necessarily today.
get_shareholders_topGet major shareholder holdings across reporting periods, not only the top ten. Returns info grouped by period and normalized members. Use object_id only where detail_available=true. Percentages may be null; *_raw preserves text.
get_shareholder_detailGet holdings and trading details for one shareholder object.
get_fund_holdings_latestGet disclosed fund holdings and portfolio weights with cursor pagination. Holdings reflect disclosure dates, not necessarily today. Pagination is in top-level page; keep filters unchanged and pass next_cursor verbatim.

get_market_statusGet CN/HK/US trading status and RFC3339 market-local time in one response. No market or symbol filter. Returns markets with market, market_time and trade_status codes; this is current status, not the trading-session schedule.
get_report_calendarGet earnings and results events with date/symbol/market filters and cursor pagination. Returns data.events and top-level page; empty events means no matches. For later pages keep filters unchanged, pass page.next_cursor verbatim, and use data.from/data.to from the first response
get_dividend_calendarGet dividend events with date/symbol/market filters and cursor pagination. Returns data.events and top-level page; empty events means no matches. For later pages keep filters unchanged, pass page.next_cursor verbatim, and use data.from/data.to from the first response if dates wer
get_split_calendarGet split events with date/symbol/market filters and cursor pagination. Returns data.events and top-level page; empty events means no matches. For later pages keep filters unchanged, pass page.next_cursor verbatim, and use data.from/data.to from the first response if dates were o

低延迟(10-50ms)的流式数据推送,适合实时行情看板、量化策略与 Agent 自动化场景。
ping / pong — 连接心跳检测unsubscribe — 取消订阅全量行情需在连接时协商 permessage-deflate;消息格式、心跳、断线重连与恢复订阅见官方连接指南。
以下示例使用 Node.js 的 ws 库。先执行 npm install ws,设置环境变量 TICKDB_API_KEY,将代码保存为 market-stream.cjs 后运行 node market-stream.cjs。订阅品种和全市场集合须符合 Key 权限,代码以产品目录实际返回为准;只需普通行情时,将 fullMarkets 设为空数组。
perMessageDeflate 直接在 new WebSocket 中启用,压缩在握手阶段协商,ws 自动解压消息。示例同时处理普通单条消息与全量快照、增量更新的数组消息。浏览器原生 WebSocket 不接受该选项。
