What is the trade etiquette for Poe2? Only usually deal on D2R so I just want to make sure I am following all of the rules/etiquette. Thank you in advance.

A lot of people follow the 2/3 rule,- like in many other threads on this site. I am sure you are familiar with it. Whomever has the lowest count gives the fg/item first, unless any of the trading party feels like requesting a mediator.

At the moment the economy is very fresh for Dawn of the hunt. Further on in the season you'll want to get a trade link by listing an item on PoE trade site before trading. You can follow this guide here ----> https://forums.d2jsp.org/topic.php?t=105515517&f=122 to learn how too.

And ofc, never mention jsp or fg in-game Good luck and happy hunting.
