I tell you, no matter what timeframe you trade, you only need to satisfy
Positive Expectation = [Average Profit - Average Loss - Friction Costs]
These three factors. As long as the result after subtraction is positive, you make money. Making money means controlling these three elements.
So, how do you stay positive in the long run?
It inevitably requires quantification/systematization. If full automation is impossible, at minimum you need AI + human-machine collaboration. AI generates high-quality signals that directly intervene in the above formula's [Average Profit = Win Rate * Average Profit].
Since the signals mined by AI have asymmetrical advantages and are superior to human-selected signals in most cases, intervening in this part is the starting point for profitability. The rest is personal discipline—controlling your own [Average Loss].
What guarantees long-term losses? Retail emotionalism, technical analysis producing garbage signals, news-driven emotional trading, repeated erroneous analysis, wrong order entries, high-frequency fees, and other low-margin-for-error behaviors.
Stacked together, this creates an exponential negative cumulative effect: eventual liquidation.
A lot of the time, what bro calls the "fate of retail investors" refers to exactly this:
Exponential error accumulation effect.
