The difficulty of trading lies in never finding an exit in a lifetime: the vast majority of people, their entire lives, cannot break free from the shackles of profit. They've tried every method—every indicator like moving averages, MACD, Bollinger Bands, and so on; they've used Dow Theory, candlestick patterns, Elliott Wave Theory, even Gann Theory; they've studied following the big players, capturing the main forces, value investing, fundamental analysis; they've participated in investment forums, expert lectures, trading chat groups, and master groups. Yet, they can never turn a profit, like mice trapped in a maze, unable to find an exit in their entire lives, unable to walk out, only to suffocate inside. After studying trading for a lifetime, they still suffer losses; after thirty years of investing, they remain old losers.
