Do market makers go against a c|ient's position? in forex

By definition, a market maker is the counterpart to all its clients' positions,
and always offers a two-sided quote (two rates: BUY and SELL). Therefore,
there is nothing personal between the market maker and the customer.
Generally, market makers regard all of the positions of their clients as a
whole. They offset between clients' opposite positions, and hedge their net
exposure according to their risk management policies and the guidelines of
regulatory authorities.
