At more than $50 trillion dollars, the U.S. market is the largest equity market in the world. With Global Trading Hours (GTH), traders can conveniently access the broad U.S. market during their local trading day around the clock.

Cboe index options, including S&P 500^® Index (SPX) options, Mini-SPX^® Index (XSP) options, and Cboe Volatility Index^® (VIX) options are available to trade nearly 24 hours a day, five days a week. With 24x5 trading hours, U.S. index options are globally accessible, allowing market participants to trade or hedge the broad U.S. market and global equity volatility across all time zones, day and night.

In addition to GTH, a brief Curb session following Regular Trading Hours (RTH) is available for traders to adjust, unwind, or close out trades. Curb sessions are all electronic trading, 3:15 p.m. – 4:00 p.m. CT Monday through Friday and are limited to SPX^®, XSP^® and VIX^® options only. SPX FLEX^® options can also be initiated. All activity during the Curb session will have the same Trade Date as the preceding RTH session. This in turn maximizes the time overlap with related future contacts. All hours are shown in each city's respective time zone:

*Trading hours are determined by the time in Chicago. Note that Daylight Saving Time (DST) procedures vary by time zone and will affect the times shown here. For non-U.S. cities shown in this table, the trading hours may shift by one hour as the U.S. changes between Standard Time and Daylight Saving Time.
