Yes, if the broker is acting as a true broker and simply moving your trade on to the interbank market, then they will make the spread on your trade minus the smaller spread on the interbank market, plus the difference in the swap.

However, like I said, I don't think many brokers actually move trades on to the true interbank market - where another party would be on the other side of your trade. In the vast majority of cases, your broker acts as the counterparty, which puts them at risk unless they are hedging properly in the interbank market.

There are many retail brokerages in the last couple years who have folded for this reason. They don't hedge, they are on the wrong side, they lose their cap, customers withdraw profits, poof, goodbye. And goodbye to customer's profits if they didn't get them out before the "poof" stage.
