Trading on PS5 - is it possible?

Is trading from this site avaiable on PS5?

I have whispered 200 people who put item on sale seconds before I whispered them and noone answered.

Man, this game needs some serious tutorials since a lot of very important things are not explained at all.

If you need to go outside the game to read forums, watch youtube videos and look for something that you need ingame or can do in game, it’s really bad design.

Is trading available or I’m just wasting time sending these whispers to people?

yes, iv been trading a bit on ps5, quite easy id say, both selling and buying, no issues so far.

we cannot trade. consoles show offline on trade site. we are locked out of it.

nope.
we are all offline.

trade is fail.,

When you say "we all offline" - how do you know that, where do you see that?

Thanks
