The trend judgment of foreign exchange market mainly depends on speculators' understanding of foreign exchange brokers, which can be analyzed from four aspects. First, the cycle problem. Cycle problem is a problem in every market. For example, the interest rate cycle of the central bank has an important impact on the asset market. If investors master its interest cycle, they will have great profit opportunities in the asset market. The foreign exchange market also has a cycle, and the change of real interest rate in the United States is one of the factors that affect the dollar cycle. Second, the market itself is a tool to digest expectations. For example, the market expects that a new cycle will begin after the US interest rate hike cycle has passed, and the factors affecting market development will not be known until then. In the foreign exchange market, foreign exchange speculators generally regard sudden political events as a speculative cycle. The urgent task for foreign exchange speculators is to find out the cycle change and how to adopt the correct investment strategy in this cycle. Third, the formation factors of the foreign exchange market trend. In fact, the factors that form the trend of the foreign exchange market are all the same. The only difference lies in risk control and the timing of entering the market. If the margin leverage ratio of foreign exchange speculators is high, the accuracy should be extremely high when they first enter the market. Once they make a profit, they should quickly distinguish between medium and long-term trends. Fourth, observe the trading chart of the foreign exchange market. There are many ways to judge the trend, but the most basic thing is to observe the foreign exchange trading chart from a long-term perspective, judge according to the price trend, observe the characteristics of price changes and the factors affecting price changes, and master these speculators, so as to basically judge the foreign exchange trend.
