Official PoE Trade side for PS4 users

Hi guys,

I am wondering if us, ps4 users, can use PoE trade to trade with other players on different platforms.

For example, can I use my PC to trade for my ps4 account?

no, all platforms are completely separate.

I use official trade just to check what I should price an item at.
But the console market is F'd and I have been just checking others prices on console and accepting that.
Lately I am just dumping in a quadtab unpriced and accepting offers.
Only problem there is people are looking through tabs for price, so I'm probably getting skipped along with the other 1000 unpriced items.
At least I identify my items before selling.
Console trade is so disgusting, I am usually just buying, or treating it like SSF.

No, to your trade question.
Cross platform MAY be coming, but I don't think we will ever see PC/console interaction.
