Yeah SEDI is really awkward to use. Not intuitive at all.
My buddy looked and showed me a report that has no recent insider trading reported at all. You can see it here https://www.dropbox.com/sh/tonofey4ux4k94x/TJhwJO1oGL.(temporary link) It shows, for example, Peter Kent registering as an insider. But it can take awhile depending on the nature of the insider trade - I believe they don't even have to report for 10 days on most trigger events. After reporting it can take one to two days to show up on SEDI after filing - I think it must go through a review process before showing up.
