Since 1980s, the ways and methods of online trading of international foreign exchange margin have made great progress. Especially with the popularization of internet technology and the rapid increase of users in the foreign exchange market, the old foreign exchange margin model has become increasingly unable to adapt to the development of the new market. In particular, the profit model of foreign exchange dealers has become the focus of discussion among industry practitioners. At present, this industry is still occupied by the market maker system represented by fxsol. This trading system has made great contributions to the development of the world foreign exchange industry. Regulatory companies with considerable financial strength still provide customers with efficient and high-quality foreign exchange trading services, but the market is quietly changing.

Foreign exchange dealers send customers' instructions to banks through the straight-through processing system-STP, and conduct real-time transactions according to the bank's price close to the customer's price. During the period of high transaction volume (especially when the quotation fluctuates greatly due to the data market), the order may be suspended, which means that the order has been executed but remains in the pending order window waiting for the matching transaction of the banking trading system. During your stay in day trading, there may be multiple orders to be processed. The increase of the waiting list sometimes affects the bank's delay in confirming some orders, and even refuses to match the customer's orders when the price does not match. Because banks are the dominant players in the foreign exchange market, trading customer orders through STP trading mode can ensure that customer orders really enter the international market to the greatest extent, and also make foreign exchange dealers who lead the matchmaking transactions stay out of the market and earn profits by providing services, thus ensuring the fairness of customer terminals participating in the foreign exchange market. Due to the complexity of technological innovation, there are not many companies adopting STP mode at present, but as the future development trend, it has gradually been favored by investors.
