When it comes to HFT, it is generally recommended to use a **No Dealing Desk (NDD)** broker or an **Electronic Communication Network (ECN)** broker¹. NDD brokers allow customers to trade directly with the interbank rates, which can help traders in some cases but hurt them in others¹. Trading with an NDD broker assures the trader that their broker has no conflict of interest with their trades¹.
An ECN broker, on the other hand, technically takes orders from clients and sends them directly to a pool of liquidity providers. The quoted prices displayed by ECN brokers are some of the best you will find as they come from multiple institutions and market participants².
