A-Book and B-Book are terms unique to brokers. In foreign exchange transactions, brokers can choose to be counterparties and not sell orders to the market and liquidity providers, which are called B-Book ;

You can also choose to pass the order out and throw it to the market, called A-Book. (STP/ECN/DMA are all types of A-Book). However, from the nature of understanding, every list will eventually have an opponent.

If you want to buy 1 lot of EURUSD, the broker will sell 1 lot of EURUSD. If it makes a profit, the broker will make a loss. On the contrary, if it makes a loss, the broker will make a profit. This is the B-Book.

If the broker sells the order to the liquidity provider at the corresponding price, no matter whether you make a profit or a loss, the broker only gets the commission for your trading volume.

UITT, a long-established European brokerage, is a pure A-position trading platform. For investors, everyone has always had a great affection and trust in A-Book, and they all hope to choose pure A-Book, because A-Book -Book is valuable in execution.
