Is it possible to predict every step accurately? That's a matter for the gods, not for me. I only understand starting from the results; when the market clearly indicates a rise or fall with prices, I follow along. The essence of systematic trading is to follow rather than guess. The old saying on Wall Street goes: 'A good trader has no opinion. The direction of the market is my opinion!' Following the trend is often disparaged as 'buying high and selling low,' and it's easy to incur losses. It’s simply that the clearer the trend, the smaller the probability of its continuation, and the risk of reversal increases sharply. Thus, buying at the top and selling at the bottom has become an inescapable nightmare. Losses stem from one fundamental error: misjudgment. The only correct action is to stop-loss. The most dangerous mindset is taking chances! The market will always be naughty, fluctuating, and unpredictable. Only by persistently stopping losses can one remain in the game and retain the capital to participate in the next round of opportunities. Trading is not about who is right more often, but about who lasts longer.
