Electronic-Only
Some contracts trade only on CME® Globex®, either "continuously" or only during U.S. day-time hours. These contracts do not trade via open outcry on the CME trading floors. For these products, the CME Globex session and the Trading Day are synonymous and concurrent. Examples of "continuously" traded contracts include:

• CME E-mini(TM) Stock Index Futures,
• CME Weather Futures.

Contracts that trade electronically only during day-time hours include:

• TRAKRS® Futures.

For most contracts, the first CME Globex session of the week starts on Sunday, with the opening rotation starting at 17:00 CT and trading continuing until Monday afternoon. Similarly, each subsequent Trading Day begins with the start of the next CME Globex session, at varying times in the afternoon on Monday through Thursday. The E-mini futures contracts have unique schedules Monday through Thursday afternoons to accommodate an earlier transition to the next trading day. These expanded schedules enable customers to respond to key equity earnings news in the late afternoon.
