How this service works
El Niño event composites from El Niño Market Watch: 14 historical events (1951–2026) across 21 commodities, indexed-to-100 price paths around event onset with median/p25/p75 envelopes — the computed asset behind the dashboard charts.
Output
A JSON object keyed by commodity, where each entry contains arrays for median, p25, and p75 indexed price paths (normalized to 100 at event onset), a window_months array indicating the month offsets relative to onset, and an events array with the individual historical event price paths across the 14 El Niño episodes from 1951 to 2026.
Example use cases
Commodity strategy backtesting
“Get me the full El Niño price composite data — all 21 commodities with their median and quartile envelopes — so I can backtest a long/short strategy that triggers at El Niño onset.”
Research report on ENSO market impact
“I'm writing a research report on how El Niño affects commodity markets — can you fetch the indexed price paths from the El Niño Market Watch composites so I can show how prices evolved in the months around event onset across past episodes?”
Dashboard chart data retrieval
“Fetch the underlying composite data behind the El Niño Market Watch dashboard charts — I need the p25, median, and p75 price envelopes for each commodity across the 14 historical events.”

Endpoint
GEThttps://trading-perps.vercel.app/api/compositesWhen to prefer
Choose this endpoint when you need pre-computed, historically normalized commodity price composites specifically tied to El Niño event onset — particularly for backtesting ENSO-driven trading strategies, building research charts, or comparing current El Niño conditions against historical templates. It is purpose-built for the 21 ENSO-sensitive commodities tracked by El Niño Market Watch and saves the work of manually aggregating and indexing 14 historical episodes.
