There are many reasons for the short-term fluctuation of foreign exchange, which can be roughly divided into three types;

First, the impact of sudden financial policies or financial events. This is a price fluctuation that belongs to macro fundamentals. For example, the Federal Reserve suddenly announced a rate cut and other macro events.

Second, on the eve of the start of the new york foreign exchange market or the London Stock Exchange market, due to the uncertainty of market expectations, investors have panic, and a large number of selling may cause the opening price to jump instantly.

Third, in the process of trading, when a large-scale transaction in the same direction occasionally occurs, there will be great fluctuations in a short time. This probability is small, but it happens sometimes.

What can't be done can be strict with me, or Baidu hi me.
