Auto-trade is live in Path of Exile 2, which is part of the third major update of the game's early access, and it allows you to mediate the purchase and sale of different items.
The latest addition, already announced in advance, is perfect for those approaching the endgame (of what's available in the current build). It saves you from micromanaging your purchases and sales, but you'll have to clear a fair bit of early-game content to use the system.
