Binary Index Options Trade in Extended Hours
If you trade options, the Exchange may now list binary options on eligible broad-based index options to trade during Global Trading Hours (GTH: 8:15 p.m. previous day to 9:25 a.m. ET, Monday–Friday) and Curb Trading Hours (Curb: 4:15 p.m. to 5:00 p.m. ET, Monday–Friday). This extends the hours when binary index options can trade beyond Regular Trading Hours (9:30 a.m. to 4:15 p.m. ET).
Regulated Alternative to Off-Exchange Binary Venues
The Exchange states that listing binary index options during extended hours offers investors a centralized, regulated alternative to off-exchange venues that offer similar binary-style index products nearly 24/7. The filing says this may increase transparency and centralized price discovery compared with platforms that are not national securities exchanges.
Specific Indexes Eligible for Extended Hours
Binary options on certain exclusively listed broad-based indexes would be eligible to trade during GTH and Curb; the filing explicitly notes that binary options on SPX, VIX, XSP, RUT, and MRUT would be eligible for GTH and Curb trading. For its initial launch, the Exchange intends to list the same strikes during GTH as are listed during Regular Trading Hours.
