Sell to the right leaguemate

1. Open Trade → Demand Radar, pick the league, choose Sell a player or pick, and select the asset from your roster.
2. Being bought lists potential buyers based on recent trade history: leaguemates who have traded for that player in their other leagues, or already hold him elsewhere. Those are your first calls.
3. Check the typical completed-trade price in your format. Use it as a starting point when pricing the player.
4. Open the Trade Calculator, switch to Find a partner, add him to what you are shopping and pick what you want back (youth and picks if you are rebuilding, proven vets if you are contending). Every team is scored for fit with a suggested even deal and the reasons for and against. Load deal opens it in Price a deal to edit before you send.
5. Send the best one or two as normal offers, or use Mass Offers to put the same ask in front of the whole league with an expiry.
