I think he still does, but might not be putting it on the Trade Busters google sheet. He told me that one of his hedge funds is flat every night. It has been a while, but he had a trade called Icarus, which he might be using for the hedge fund, and I think it is a 0 DTE. When he started the hedge fund he indicated that he would no longer participate in any discussions regarding Icarus.
In the Facebook group, there are mixed results with 0 DTE, I saw a post the other day with the headline Is the 0 DTE trade now officially dead. I stopped actively following the group when it went almost 100% 0DTE discussion, but there is still a lot of activity there.
