Price a trade you were offered

1. Open Trade → Trade Market and choose your league under Match my league. The list now shows only trades from leagues with your size, scoring, QB format and starting lineup.
2. Type the main player or pick in the offer into Player or Pick. The card at the top gives the typical completed-trade price in your format, the list price on the same dates, and the difference between the two.
3. Read a few recent trades. Each shows both sides and what each side received at the prices of the day, so you can see what a package for this player has looked like.
4. If the card says there are not enough comparable trades, switch Match how to Format only for a wider pool.
5. Repeat for the main piece on the other side. Compare what you are giving against what you are getting at completed-trade prices, not list prices.
6. Want to know who else would pay? Open Demand Radar for the same asset: it lists the leaguemates who have traded for it in their other leagues.
