Put two stacks of items side by side. We'll total the values, flag dead demand and dropping items, and tell you whether the trade is fair, a win, or a loss. Share the URL — it captures the full comparison so a trade partner sees the same thing you do.

How we judge trades
- Fair — the two totals are within 10% of each other. Most traders will close this without argument.
- You win / You lose — the gap is more than 10% in one direction.
- We raise warnings when your side contains items with dead demand or currently-dropping stability, because headline value overstates what partners will actually give up for them.
- Prices refresh every 10 minutes. If a trade is borderline, check the specific item pages for the latest trend.
