What Win / Fair / Lose means
Fair = both sides land within ±10% by community values. “In your favor” or “against you” just describes which side is heavier — a sanity-check, not advice.
Where the values come from
Community reference points via the Traderie community, refreshed periodically (not live). They're a sanity-check, never a price, and we're not affiliated with the game or its publisher. Some items have no value yet — we say so instead of guessing.
How to read the meter
The shaded center band is the fair zone; the marker leans toward the heavier side. Quantity assumes the same form for each of a stacked pet.
