Futures Expiry Roll Calendar API

Use this endpoint when you need a full annual roll calendar — all four quarterly expirations and roll dates — for a specific CME or Eurex index futures product. It is preferable to sibling endpoints when you need to plan ahead for an entire year rather than just the next contract or current front month. It is ideal for strategy backtesting setup, risk management scheduling, or building trading calendars.
