RE:insider selling If you click on "marker", I believe it will show transactions that are made, but not yet filed. So they would probably show up the next day.
But before transactions are filed, the number of shares sold/bought are often not correct. I don't remember why, but I read an explanation somewhere on their site once. So if you are looking for precise numbers, you'll have to wait until transactions are filed, which takes anywhere from a few days to a couple of weeks.
At
https://www.canadianinsider.com/recent-marker they show all insider transactions for the companies on TSX for the previous trading day. "TSX Venture Selling" shows nothing for K92 for January 23rd, so no selling from Cartesian yesterday. That doesn't necessarily mean that they're finished for now, though, as they have taken breaks before and resumed selling a few days later.
