Market Maker Broker
Also called: dealing desk, dealer
A broker that takes the other side of your trades — they profit when you lose, creating an inherent conflict of interest.
During the 2015 CHF unpeg, many market maker brokers went insolvent because their clients' losses were bigger than their hedges. The conflict of interest cut both ways — client losses became broker liabilities when the broker couldn't absorb them fast enough.
