AFAIK, there is no formula.
For trading up, you have to make an offer that makes the other party look like they got themselves a good deal without screwing yourself over. Like 🇹🇹 might give away our 1st and 3rd for their 1st. Then he might trade other picks for more picks with someone else as 🇹🇹 likes lots of draft picks.
