stock-sub

Subscribe to real-time stock market data via WebSocket long connection from receiver nodes (A-shares, HK stocks, ETFs). Use this skill when the user wants to monitor live stock prices, set up real-time alerts, or stream minute-level K-line data. The skill provides a WebSocket server that connects to receiver nodes and pushes real-time price updates to all connected clients.

实时股票数据订阅（WebSocket）

通过 WebSocket 长连接 实时接收 A 股、港股、ETF 行情数据，每 3~5 秒更新一次。

架构

Receiver Node (HTTP API) → scripts/subscribe_client.py → ws://localhost:8765 → 客户端

环境准备

pip install requests websockets
export STOCK_RT_NODE_URL="http://your-node:9100"
export STOCK_RT_TOKEN="your-token"   # 可选，无 token 时访问 [充值链接](https://jqhl.jqcloudnet.cn/#/pages/stock-subscription/index) 充值

快速开始

一次性查询（验证连通性）

python3 scripts/subscribe_client.py --symbols 00700.HK 600519.SH --once

启动 WebSocket 推送服务

# 基础订阅
python3 scripts/subscribe_client.py --symbols 00700.HK 09988.HK 600519.SH

# 指定节点和端口
python3 scripts/subscribe_client.py --node-url http://your-node:9100 --ws-port 8765 --symbols 00700.HK

# 涨跌幅告警（±2% 触发）
python3 scripts/subscribe_client.py --symbols 00700.HK --alert-pct 2.0

# 输出到文件
python3 scripts/subscribe_client.py --symbols 00700.HK --output ticks.jsonl

编程方式启动

from scripts.subscribe_client import StockWSServer

server = StockWSServer(
    node_url="http://your-node:9100",
    symbols=["00700.HK", "09988.HK"],
    poll_interval=3.0,
)
server.add_callback(lambda sym, tick: print(f"{tick.name}: {tick.close}"))
server.run(port=8765)

AI Agent 集成

from scripts.ai_agent_integration import StockDataAgent

agent = StockDataAgent()
agent.install()  # 检查依赖、验证节点连通性

# 完整工作流（订阅 + 告警监控 60 秒）
import asyncio
asyncio.run(agent.complete_workflow(['00700.HK', '600519.SH'], duration=60))

告警策略

告警规则配置见 references/strategy_config.json，内置策略：

  • limit_up_down：涨停/跌停监控
  • big_move：大幅波动（≥ ±5%）
  • vol_spike：成交量异动（≥ 近5日均量3倍）
  • price_breakout：价格突破近20日高点
