TongDaXin: China's Bloomberg Terminal | Generated by AI
Question: What is https://www.tdx.com.cn?
Answer:
It’s 通达信 (TongDaXin) — one of China’s most dominant stock market analysis and trading software platforms, built by 深圳市财富趋势科技股份有限公司 (Shenzhen CaiFu QuShi Technology Co., Ltd.).
Think of it as the Bloomberg Terminal equivalent for Chinese retail and institutional investors, but far more mass-market. It’s been the de facto standard for Chinese A-share trading software for decades.
What they offer:
- Broker systems — white-label trading terminals that most Chinese brokerages (券商) use as their underlying platform
- Personal editions — tiered from free basic to paid Professional/Research versions, covering A-shares, HK stocks, US stocks, and futures
- Market data — real-time quotes, historical tick data, full order book; their data format (
.datfiles) is widely used in Chinese quant circles - Research terminal — institutional-grade tool, including a bond terminal
- AI platform — they’ve recently added:
问小达AI(their own LLM-based Q&A), an agent marketplace, and notably 通达信MCP (an MCP server for financial data) and TdxClaw — which is interesting given you build CLI agents
Why it’s relevant to you specifically:
The TdxClaw and 通达信MCP products suggest they’re building MCP-compatible financial data APIs — meaning you could potentially connect Claude or your own agents to real-time Chinese market data via MCP. Given you already build tools like iclaw and zz, this is worth a look if you ever want to build a Chinese equity research agent.
Also their historical data format (通达信数据) is well-documented and widely used in Chinese open-source quant projects — worth knowing if you ever touch A-share data pipelines.
