Your welcome.
I have tried to create the trading pair, Steem-TRX but I have been unsuccessful. Because Steem is not on the Token list and I don’t have a Contract Address. I believe it’s referring to the smart contract, which determines the relation ship between the token and the other token in the pair. But I am not sure, I will ask the developers for this information: about the status of this contract and if possible obtain its address.
