Do not use stocks.exchange. They are one of the smaller exchanges but a coin I needed to trade was only listed there as the exchange with top volume.

I have sent an ETH deposit and the money has not been credited 24h later, of course also not support ticket response.

So avoid it.

And yes I did check if my tx went thru and if the address was correct......

UPDATE: Deposit was credited

So I checked today and the money all of a sudden was in my account. It looks like the exchange is overloaded, although I do not understand why such a thing is not automated.
