According to the report of NBD, after detecting a low of 70.698 on March 17, the US Dollar Index continued to rebound and hit a high of 73.895 last Thursday. Last Friday, the European Central Bank decided to keep its refinancing rate at 4% unchanged, causing a technical pullback in the dollar. The "weak dollar" may have already hit bottom, and the foreign exchange market may have entered a major turning point for change. A "major turning point" has two key elements: one is long-term overbought or oversold conditions, and the other corresponds to a "major event." Both are essential. The current international foreign exchange market is experiencing these two "necessary" conditions.
