About this skill
The Problem
ETF market data is often split across gain leaders, turnover boards, capital-flow boards, net creation/redemption boards, and premium boards. Engineers and research scripts need a single structured endpoint to fetch ranked lists with consistent filters and pagination. This skill wraps GF Securities' etf_rank API into a predictable parameter model for market checks, data pipelines, and automated reporting.
How It Works and Limits
The skill expects the environment variable GF_SKILLS_APIKEY. If the key is missing, the call stops and points the user to request a key. Requests go to the GF MCP gateway with service_name set to etf_rank and tool_name set to finance-api_product_etf_rank_get. Key inputs include:
- Rank type: type supports 1 gain, 2 loss, 3 turnover, 4 main capital, 12 net creation/redemption, and 13 premium.
- Pagination: page starts at 0, and size defaults to 10.
- Filters: sameIndexFilter limits one ETF per underlying index, while continueRiseLimit filters by consecutive rising or falling days.
Use it when you need structured JSON, a fixed ranking basis, and paged pulls. It is not a replacement for order execution, portfolio backtesting, real-time tick data, or a fully cached, cleaned local database. Missing keys, rate limits, or changes in ranking definitions can affect results.
Use Cases
- Pull top-20 gain, loss, and turnover ETF lists from a post-close monitoring script.
- Use `sameIndexFilter` in an ETF research pipeline to suppress duplicate index rows.
- Filter consecutive movers with `continueRiseLimit` and emit paged alerts.
- Export main-capital and net creation/redemption boards as structured JSON.
Best For
- Quant ops staff producing post-close ETF gain and turnover briefs.
- Backend engineers building ETF data pipelines with paged structured pulls.
- Fund analysts filtering duplicate indices and consecutive movers.
- Alert-script analysts checking main-capital and net redemption anomalies.
