DMarket is an NFT and virtual in-game items marketplace.

I was trying to trade a few of my skins out today for some new ones and after accepting the trade, none of the skins went to my dmarket inventory. What did happen, is my existing skins (that I have had for a quite a while) were taken from my steam inventory, and placed under a 7 day trade lock on dmarket. So in the end, the skins I attempted to trade were taken from my inventory, put on trade lock, and I received nothing. Like I said, these skins were not on trade lock, I have had them much longer than a week so I don't see why my skins were taken put on trade lock on dmarket, and then I got none of the skins I tried trading for. I've had many positive transactions on dmarket in the past but this is concerning to me.
