The longer you trade, the more you understand one principle: those successful traders have already laid out the core ideas. Many people find it unfathomable, to put it simply, because they haven't truly understood it.

Almost every trader has gone through a detour—madly pursuing "certainty." Studying candlestick charts, comparing technical indicators, trying to grasp every market wave. But the more you study, the more you realize that the market never offers 100% certainty. The true solution is to find that relative certainty amidst uncertainty.

So the question arises: is the core of trading really just "finding key positions, setting stop losses, and then placing bets"?

Friends around me who invest traditionally usually react by trying to dissuade me: "This industry is too risky, so-and-so lost money in stocks, so-and-so went bankrupt in futures." I would respond by asking: "Do you know what the fundamental difference is between gamblers and professional traders?" The answer is not luck, but whether they have undergone systematic training.

I never dare to call myself a "trading expert," but one thing is certain: if you see trading as a probability game, professional training allows you to master the "probability advantage." This is not random gambling, but rational operation based on rules, systems, and risk management.

The phrase "Set stop-loss bets at key positions" may sound simple and straightforward at first, but it actually hides all the intricacies of trading. It's not about impulsively opening a position; rather, it's a complete system that covers seven core questions. Each question is worth taking the time to refine: How to choose the time cycle for the order? How to determine the trend direction? How to find the key entry point? How to allocate positions? How to set stop-loss? ... These are the real lessons.
