Profitable dips are all about not just hitting the bottom right once, but how many times you can withstand setbacks. A friend once went all-in at the ETF bottom; his judgment was indeed correct at the time, but he still ended up losing out— the core issue was simple: reckless capital allocation and lack of psychological preparation.

Looking at it from another angle, investing is like warfare. Technical analysis is your spear, used to launch attacks; but the real key lies in the shield—capital management and mindset. If the shield leaks wind and rain, even the sharpest spear is useless.

First, let's talk about capital. What's the biggest taboo in low-buying? One is "bet everything," and the other is using living expenses to gamble. Successful people follow a simple principle: invest only with money they can afford to lose. How exactly? Divide your total funds into several parts, keep each low-buy position within 10%, and set a stop-loss— for example, exit if the price drops 5% below the cost. The advantage of this design is that even if one operation fails, it won't cause fundamental damage.

The problem with that friend was that he poured all his funds, originally meant for other purposes, into the market. When market volatility hits, his psychological defense collapses immediately—because losses directly impact his livelihood. A smarter approach is "layered entry." For example, in support levels, stagger your positions: invest 50% of your budget at 3070 and 3080 each. This not only smooths out your cost basis but also prevents you from bearing huge psychological pressure all at once.

Now, about mindset. Most people make the mistake of caring too much about the result—how much this trade can make. In fact, the focus should be reversed: pay attention to the process—am I managing risk carefully? Am I sticking to my discipline? This "process-oriented" approach helps you endure volatility and survive longer. The success or failure of low-buying is never determined by a single judgment but by whether you can establish a complete defense system. Those who can make consistent profits over the long term, without exception, have internalized their "immune system"—that is, risk control—into instinct.
