The recent performance of the Japanese Yen has been quite outrageous, with no stable trend at all. Look at its movement—sometimes soaring, sometimes plunging, completely unpredictable. Many people get caught up in these extreme fluctuations, confidently chasing highs, even managing to screenshot and show off, only for the market to turn around and cut their gains in half. Is this rapid rise and fall a natural market evolution, or is there some kind of pattern behind it? It's definitely worth pondering. For traders, in such highly volatile markets, risk management becomes especially important.
