description	Python moexalgo library workflows for HI2 DataFrames, .env session.TOKEN setup, Market.hi2, Ticker.hi2, Herfindahl-Hirschman concentration, hhi_* metrics, daily EQ/FO/FX concentration analysis, offset pagination, pivots, groupbys, interpretation bands, and missing-row caveats.

MOEXAlgo HI2

Overview

Use this skill when the user wants HI2 through the moexalgo Python package and DataFrame analysis.

Access note: Promo includes HI2. Стартовый / Starter free-token availability is planned at T - 1 day; verify current access before promising it.

Quick Start

python -m pip install "moexalgo[dataframe]" python-dotenv

import os
from dotenv import load_dotenv
from moexalgo import session, Market, Ticker

load_dotenv()
session.TOKEN = os.environ["APIKEY"]

eq = Market("EQ")
market_hi2 = eq.hi2(date="2025-01-10")

sber = Ticker("SBER")
sber_hi2 = sber.hi2(start="2025-01-01", end="2025-01-31")

Core Workflow

1. Use Market("EQ"|"FO"|"FX").hi2(date=...) for all instruments.
2. Use Ticker(...).hi2(start=..., end=...) for one instrument.
3. Filter or pivot by metric.
4. Use library offset for pagination where supported; do not pass raw REST start to library methods.
5. Apply broad concentration bands when useful.
6. Explain missing rows as possible coverage, entitlement, date, or participant-threshold issues.

Boundary

For raw endpoint URLs, curl, JSON/CSV, or no-Python workflows, use the direct HI2 skill instead.
