Global Economy Index (GEI)

A composite macro indicator built from 5 real-time signals that reflect the strength of the global economy:
The idea came from @Thomasonmarkets on X

// 1. Inverted US Dollar Index (1 / DXY) – Stronger USD = tighter global conditions
// 2. Baltic Dry Index (BDI) – Measures global shipping demand
// 3. China 10Y Yield – Proxy for Chinese economic health
// 4. Copper/Gold Ratio – Risk-on vs safe-haven demand
// 5. Crude Oil – Global industrial demand
//
// Each input is standardized via 252-day Z-scores and equally weighted.
// A rising GEI suggests global expansion (risk-on).
// A falling GEI suggests economic contraction (risk-off).
//
// Use as a leading signal for the business cycle, risk appetite, and liquidity regimes.
// Can be shifted forward (e.g. 3–6 months) to anticipate turning points in PMI, equities, and crypto macro cycles.
