====== Trades ======
Trades determine what specific item stack a [[mc>Villager]] or [[mc>Wandering_Trader|Wandering Trader]], usually grouped together as [[entities:merchants]], wants to trade with a player.
These trades can be found in a data pack under the ''trade'' folder in a namespace.
They are then used in [[mc>Tag|trade tags]] so a merchant can choose their respective trades.


===== Fields =====
^  Name  ^  Description  ^  Type  ^  Default Value  ^
| ''wants'' | The item stacks the merchant wants from the player. | A list of 1 to 2 [[trades:trade_entries|trade entries]] | |
| ''gives'' | The item stack the merchant gives to the player. | A [[trades:trade_entries|trade entry]] | |
| ''max_uses'' | How often a player can trade this trade with a merchant before the trade gets disabled. | A positive integer | |
| ''trade_experience'' | The amount of trade experience to grant the merchant upon trading. | An optional integer | ''1'' |
| ''price_multiplier'' | The multiplier that affects the price of the first wanted item stack based on the trade's demand. | An optional float | ''0.0'' |
