ALGOPACK HI2
Overview
Use this skill for direct HI2 endpoint access and concentration analysis. HI2 is a Herfindahl-Hirschman style metric calculated for supported EQ, FO, and FX instruments.
Access note: Promo includes HI2. Стартовый / Starter free-token availability is planned at T - 1 day; verify current access before promising it.
Quick Start
curl -L "https://apim.moex.com/iss/datashop/algopack/eq/hi2/SBER.json?from=2025-01-01&till=2025-01-31" \
-H "Authorization: Bearer ${APIKEY}"
Use date=YYYY-MM-DD for all instruments and from=YYYY-MM-DD&till=YYYY-MM-DD for one ticker.
Core Workflow
- Choose market
eq, fo, or fx.
- Fetch all instruments by
date or one ticker by from/till.
- Normalize ISS
columns plus data arrays into rows before filtering, writing tables, or charting.
- Filter by the requested
metric or inspect returned metric values.
- Apply broad bands when useful: below
1500, 1500-2500, above 2500.
- Match output to the request: CSV/JSON tables for handoff, simple HTML charts for browser output, Matplotlib or pandas plotting for notebook/script output, and the app's existing charting stack inside an app.
- Explain missing rows as possible coverage, date, entitlement, or participant-threshold issues.
References
Read references/hi2.md for formula, endpoints, metrics, fields, interpretation bands, pagination, and output patterns.
Boundary
Treat HI2 as a screening and market-structure metric, not as a buy/sell signal.
