Forex brokers that route orders through the Dealing Desk and quote a fixed spread. This type of dealer makes money thru the spread and by taking positions against the client. A Dealing Desk Forex acts as a Market Maker where they create the market for traders. When a trader decides to sell his position, they will buy it from him and when that person decides to buy the DD will sell that position. That is they always take the opposite side of the trade and create the market. The trader never sees the actual market quotes which lets the Dealing Desk brokers manipulate the quotes to wherever they need to complete the client order. Basically a dealing desk provides pricing along with liquidity and makes trades.
To list just a few of the many Dealing Desk Brokers:
10PIPS, EXNESS, Finexo Global Investments, Ava FX, TFIFX, LiteForex, Master Forex, InstaForex, Forex WebTrader, Finotec, BTrader, Forex Place (4XP), DfxTrade, Financial Pacific and WSD Global Markets.
The No Dealing Desk brokers are either STP or ECN+STP.
