I just opened an account with FXDD. They are listed by you under "STP Forex brokers (No Dealing Desk + STP)"

On FXDD's website, on their FAQ page it's stated:
"
Do you have a dealing desk?

Yes. The function of a “dealing desk” is the subject of much speculation in the Forex business these days. Some firms promote the fact of “no dealing desk.” In all cases of retail trading, the pricing the customer sees is the pricing the customer receives. Dealers, such as FXDD, receive institutional level liquidity [pricing] from their global banks and then, with the spread widened, stream them out to their customers. Does this mean that customers are guaranteed no slippage on all orders? No. In times of extreme volatility, clients will not always get the price they clicked on. The market is a dynamic event and prices change quickly and latency may affect pricing. The critical factors here are the volatility of the market and the latency of the connection. Our dealing desk’s role is to manage the liquidity streams between us and our market makers and to ensure that the customers always enjoy competitive pricing and spreads.
"
So...I'm confused - do they have a dealing desk allowing them to manipulate the trades or not?
