CME Futures Listing Cycles and Contract Selection for Backtests

Article Machine Learning for Trading

Summary

This reference summarizes listed contract months for 35 CME futures products across equity indexes, Treasuries, energy, metals, currencies, interest rates, agriculture, livestock, and crypto. It explains the exchange’s month-code system and distinguishes monthly, quarterly, and product-specific bi-monthly listing schedules. The tables give representative listing patterns, including quarterly cycles for equity indexes and major Treasury contracts, monthly contracts for energy products, and crop or delivery-related schedules for agricultural and livestock markets.

The practical focus is selecting contracts for historical data collection. Exchange listings indicate which contracts may trade, while vendor definitions and actual activity determine which have data; far-deferred listed contracts may have no trades. The document notes that near-term serial FX contracts have limited historical depth and recommends quarterly FX contracts for backtesting. It also cautions that some near-term platinum and palladium monthly contracts have limited liquidity. These are contract-calendar and data-availability notes, not evidence of a trading strategy; the schedules are a dated snapshot and do not themselves establish liquidity or continuous-series construction.

Key ideas

  • CME products follow monthly, quarterly, or product-specific delivery month schedules expressed with standardized month codes.
  • A listed contract may not have trades or available historical data, particularly at distant expiries.
  • Quarterly FX contracts offer greater historical depth than near-term serial months in the described data context.
  • Some near-term platinum and palladium monthly contracts have limited liquidity despite their listings.
  • Historical backtests should select contract months that reflect the liquid contracts and data actually available.

## Data Collection Notes

### Source




### Important Distinction
**CME Listed Contracts** vs **Databento Available Data**:
- CME lists what contracts CAN trade
- Databento definition data shows what contracts ARE actively trading
- Far-deferred contracts may be listed but have no trades (no data)
- For historical backtesting, use the pattern that matches liquid contracts

### Serial vs Quarterly Months
For FX futures (6E, 6J, etc.):
- **Quarterly** (H, M, U, Z): Full historical depth, most liquid
- **Serial** (non-quarterly): Only near-term, limited history
- **Recommendation**: Download quarterly only for backtesting
