 The data referenced in this document covers 24/5 trading hours in US equities on a range of traditional venues. While there is currently no trading activity in traditional markets over the weekend on any venue, protocols can extend their pricing coverage to 24/7 in multiple ways, such as leveraging the pricing of [tokenized stocks](#stream-switching-example-logic) on secondary markets such as CEXes and DEXes.
