I think Saxo bank used to offer something similar. A branch office of IG group also and Swissquote. The old binary.com and a bunch of other offshore unregulated and binary options brokers.
Now it’s not anywhere I know of except maybe at banks structured product desks(that’s not available for retail). Although it may be available at some European exchanges for retail but I have found none yet.
If you or anyone have an idea of an exchange or broker accessible by retail traders that offers it, then I would like that information.
