Trade is inconvenient.

Time is wasted if the trade partner does not respond.
Please change to a market system like Diablo immortal.
Only players who own premium stash tabs can list items for sale, which is fine as it is.
The items should be deposited once on the market server, and prospective buyers should be able to visit the trade website and pay the market server for the currency needed to purchase the item, and the seller should go to the market server to pick up the payment.
Please allow market items to be browsed, purchased and listed in-game.
Diablo immortal's market system would be a good reference.
