Depending on how the Forex trading broker's activity is organized, different types of trading accounts exist. And, with that, different trading conditions.For instance, some brokers are organized as market makers. Also called dealing desks, they mirror the actual market and offer traders similar conditions via the trading platform. Effectively, the trader deals with the broker, without the positions to be transferred to the market. In this case, most likely, the broker offers a fixed spreads account and charges a commission too.Some other brokers route all or only some of their client's orders to the liquidity providers they work with. In the case all the trades go thought the liquidity providers, the brokerage house operates a no-dealing desk business. If only some of the trades go to liquidity providers, and the rest are kept in-house, the broker's model is a hybrid one – a combination between dealing and no-dealing desks.
