Infinite Trading is a minimalistic mod which prevents villager trades from locking up, making them always available and allowing infinite trading. I'm not sure where they get the items from, but as long as emeralds are involved they'll find a way. The wandering trader is supported and enabled by default. This can be turned off in the config. Traders from other mods, like the goblins from Goblin Traders, are supported as well.
All available config options:
wanderingTraderInfiniteTrades default true
When enabled, the trades of the wandering trader will never lock up.
villagerInfiniteTrades default true
When enabled, the trades of villagers will never lock up.
moddedTraderInfiniteTrades default true
When enabled, the trades of traders from other mods will never lock up. For example custom villagers, or the goblins from Goblin Traders.
minimumVillagerLevel default 1, min 1, max 5
The level a villager needs before its trades become infinite. 1 is Novice, 5 is Master. Villagers below it keep their vanilla trade limits.
tradeUsesMultiplier default 0.0, min 0, max 1000.0
When above 0, trades are no longer infinite, but can be used this many times the vanilla amount before they lock up. They restock like vanilla. For example 10 allows ten times as many trades. 0 keeps trades infinite.
removeTradeDemand default true
When enabled, prices don't go up when a trade is used a lot. Disable to keep vanilla's demand prices, which update when a villager restocks.
preventTradeLoops default false
When enabled, players can't endlessly earn emeralds with trade loops, like buying bookshelves and selling the books back. Per player, once selling an item earns more emeralds than that player spent on buying it or items crafted from or into it, their trades selling that item fall back to vanilla limits. This is counted per 20 minutes of play (the length of a Minecraft day), sleeping or changing the time does not reset it.
