btool stores ingestion, normalized series, revisions and derived calculations separately. Public pages, rules and AI tools read the same verified records.
- MARKET
- BTC uses Binance, MSTR uses Yahoo Finance with Twelve Data fallback, and gold uses Twelve Data XAU/USD spot OHLC. Only completed Monday–Friday UTC daily candles are used, with weekly candles aggregated locally. Each record retains its source run, finality, and revision.
- US 2Y
- The U.S. two-year yield comes from the U.S. Treasury Daily Treasury Par Yield Curve Rates BC_2YEAR observations, aggregated weekly while displaying the week's latest observation date.
- FILINGS
- SEC and company investor-relations pages verify statements, releases and management guidance.
- AI RESEARCH
- OpenAI Agents SDK uses internal data tools and hosted web search. Reports cite dates and sources; model memory cannot override current database snapshots.
- REVISION
- Corrected points increment their revision and archive prior values. Material derived series retain input manifests and methodology versions.
- G5 LIQUIDITY
- G5 broad money combines US M2, China M2, euro-area M2, Japan M2 and UK M4. Current FX uses each month's rates; fixed FX uses January 2020 rates. Three-month momentum is annualized and 0–6 month lead correlations use monthly log changes.
- ETF FLOW
- BTC-denominated daily net flow for U.S. spot BTC ETFs comes from Bitbo; positive values are inflows and negative values are outflows. Cumulative flow sums from the series start. Capital flow multiplies each daily net flow by the same-day BTC close, converts it to USD and accumulates it; missing same-day prices are left unmatched. Momentum equals rolling 20-day net flow minus one third of rolling 60-day net flow. Average holding cost equals cumulative USD net flow (daily net flow × that day’s BTC close) divided by cumulative BTC net flow, the volume-weighted average cost of the ETF’s net position.
- BTC / GOLD
- The estimated ratio uses historical World Gold Council above-ground stocks carried forward from verified publication dates, without future reports, interpolation, or forecasts. The worker checks daily and retains observation dates, publication dates, sources, and revisions. Gold market cap = same-day or latest completed XAU/USD spot price × above-ground stock (tonnes) × 32,150.746568627 troy ounces/tonne; underground reserves and derivatives are excluded. BTC supply remains estimated across historical halving intervals. This is a relative comparison, not authoritative supply statistics. World Gold Council above-ground stock
- TIME
- The database stores UTC; the interface displays Beijing time and distinguishes observation, publication, and market-close timestamps.
