FAQs
What does WFL mean?
WFL = Win / Fair / Loss. Win means the trade favors YOU (you receive >X% extra value). Fair is within ±X%. Loss means you lose >X%. Default threshold is ±5% — Tradekitsune standard. Use ±2% for strict trades or ±10% for casual.
How is trade value calculated?
Each pet contributes its Trade Token value: tokens(weight) = interpolate(datapoints, weight) × mutation × demand. Sum each side, compare percent difference. Weight is the only stat that matters at trade time — age is ignored.
Can I add multiple pets per side?
Yes — up to 8 pets per side. Useful for "trading 3 mid-tier for 1 endgame" scenarios. Each pet weight + mutation set individually.
Why does the calculator say Win but trader rejected my offer?
WFL is mathematical. Real traders also factor scarcity (event-locked > tier value), mutation rarity (Ascended is harder to find than Rainbow despite being just 5× vs 2.5×) and personal need. Use WFL as baseline, not absolute truth.
Is the WFL Checker the same as the Trade Calculator?
Same tool, two URLs. /calculator/trade and /wfl-checker both render the same WFL component.
