Fortunately, there are open-end put options, so the timing doesn't have to be THAT accurate.
EDIT: to be precise: I mean open-end turbo put, which have no expiration but a knock-out.
Put options have an expiration. So I'm curious what you mean by "open-end"?
Options exist with no expiration date, but they are not commonly traded. There's nothing in principle unusual about them, at least not more so than most other derivatives.
Yeah, not a thing. You can short a stock long-term, but that's an easy way to become insolvent.
Perpetual options are a thing, although not mainstream.
