I certainly know that doing oscillation wave trading back and forth will inevitably lead to a "drowning" incident, so after doing it a few times, I only used the word "gamble". If I make a mistake and hit the stop loss, then the profit from the last time is gone. At first, the market is uncertain, which easily leads to panic; the oscillation trend hasn't emerged yet, and not many people are participating, so there are actually more opportunities. Those who discover the patterns first make money. When the oscillation trend becomes very obvious, that's when many people feel safe to participate, and that's when problems can easily arise.
