Yesterday, I indeed brought the wrong order. This brother has no problem blaming me, but his current viewpoint is indeed too dangerous. The mindset of only wanting to earn and not wanting to lose must be abandoned. It's very normal to set a stop loss for short-term trades; as long as the long-term profits exceed the losses, that is considered a victory. If one cannot accept losses, then they can only make a small profit with Martin, break even, and then average down, which will explode cleanly once the market breaks out. This kind of play can easily mislead beginners; it appears very safe on the surface, but in reality, it is the most dangerous trading method. A mistake in one trade can wipe out half a month's profits.
