FanDraft does NOT transfer the value of a player during a trade in an auction draft.
Scenario: "Team A" starts with $100 / "Team B" start with $100
If Team A wins a player for $10, that amount is deducted from their Total BID $.
This would leave Team A with $90.
If Team A then trades this player to Team B, no money is transferred or added back.
Team A would still have $90, and Team B would still have $100
Different leagues treat this action in different ways, but this is how the FanDraft platform works.
If your league transfer bid$ during a draft:
This can be adjusted by including BID $ in the trade.
In the case above, you could have TEAM B include $10 in the trade, and accomplish transferring bid$ as desired.
Our recommendation is to always make sure to run some practice drafts with such scenarios to become familiar with how things work.
