Binary Index Options: Extended Trading Hours
The Exchange will allow binary options on exclusively listed broad-based index options to trade during Global Trading Hours and Curb Trading Hours. That means binary options on indexes such as SPX, VIX, XSP, RUT, and MRUT would be eligible to trade during GTH (8:15 p.m. previous day to 9:25 a.m. Monday–Friday) and Curb (4:15 p.m. to 5:00 p.m. Monday–Friday). The rule was filed March 27, 2026 and makes binary index options eligible for these extended hours similar to FLEX options.
Regulated Alternative to 24/7 Platforms
The rule permits the Exchange to list binary index options during extended hours to offer investors an on-exchange alternative to products currently sold on other platforms that operate 24 hours a day. The Exchange says listing these products on a national securities exchange provides centralized liquidity, market transparency, and securities regulation protections, and may allow trading of similar products nearly 24 hours a day, five days a week.
