Not sure. Mind explaining how does the exchange exactly works? It looks more of a search engine.
I can see that whenever you choose the pairs you want to trade, a list of exchanges is given to you. Do they buy the crypto from these exchanges using their accounts API and then re-sell it on their platform?
