I didn't have much luck with a Google search, so I'm still unsure if there's a time period teams must wait before they're allowed to trade a player they've just signed in the off-season
For example, could the Blackhawks trade Domi right now? And if so, are there any restrictions with Chicago retaining salary?
I use Domi as an example because he only signed a 1 year deal, and given Chicago isn't expected to be competitive this season, I assume he joined the Blackhawks knowing full well the team's plan is to give him a significant role for the first half of the season in the hopes he'll have considerable value come the trade deadline
