Disclaimer: portfolIQ provides factual market data only. FX rates and market prices are for analytical / informational purposes. Not financial advice. Methodology disclosed.

Markets covered

Notes:

• Tier 0: fully redistribuable per D-072 (central bank, government, or permissive open licence).
• Internal: derived/aggregated metrics only — no raw price redistribution (exchange licence required).
• Fundamentals only: regulatory filings ingested, OHLCV prices excluded (pending exchange ToS validation).
• China A-shares (XSHG/XSHE): excluded Phase 1 — HFCAA/PIPL/DSL legal risk. See Excluded markets.

Conversion to USD: available via ?display_currency=USD in Sprint 33 (not yet active). Until then, use the FX rates API for manual conversion:

FX sources: Bank of Japan (BoJ), HKMA, MAS, RBI, Bank of Korea, RBA, FRED. All Tier 0 — public domain central bank data.

Excluded markets

China A-shares (XSHG / XSHE)

China A-shares are excluded in Phase 1 due to:

• HFCAA risk: Holdings of Chinese companies via VIE structures (legal ambiguity)
• PIPL/DSL: China's Personal Information Protection Law and Data Security Law restrict cross-border data flows
• Exchange redistribution: SSE/SZSE ToS prohibit commercial redistribution of raw price data

Workaround in progress: China A-shares accessible via HKEX Stock Connect delayed data (evaluated by expert-legal for Tier 0 derivation). Decision pending Sprint 35.

ASEAN OHLCV prices

Raw OHLCV prices for most ASEAN exchanges (other than derived metrics) are excluded:

• Exchange licences required for raw price redistribution
• Covered: derived consensus metrics only (where sources are Tier 0)

Timezones

All prices are stored in UTC internally. Use the local_trade_date field for session-local date filtering:

Note on XASX DST: Australia observes daylight saving time (AEDT = UTC+11 in summer, AEST = UTC+10 in winter). Close UTC shifts between 05:00 and 06:00 UTC seasonally.

Note on XTKS lunch break: Tokyo Stock Exchange has a lunch break (11:30–12:30 JST). portfolIQ ingests end-of-day (EOD) data only in Sprint 32 MVP — intraday data with lunch break handling is planned for Sprint 35+.
