Unable to sleep, suddenly enlightened, updating a pinned message:
1. The trading market is a chaotic system (a term from logic), influenced by countless factors, so candlestick charts can only summarize past occurrences and cannot accurately predict the future. It's like humans cannot accurately predict the weather a week from now.
2. The emergence and digestion of market information will cause all factors to trend towards a single direction, so you should pay attention to periodic news and sudden news.
3. Because it is a chaotic system, theoretically your profits depend on mathematical probabilities, whether going long or short.
4. In essence, the probability here is actually the win rate and the profit-loss ratio.
5. Please pay attention to calculating the actual mathematical expectation of profits, for example, a win rate of 90% with a profit-loss ratio of 1:4. In reality, the mathematical expectation of profit is 1*0.9=0.9, and the mathematical expectation of loss is 4*0.1=0.4, so even if the unpopular approach of 'take profit and run, endure losses' is used, as long as the mathematical expectation calculation is reasonable, you can achieve stable profits.
6. So why do all the 'coaches' and 'financial bloggers' tell you that Martingale is doomed?
7. A. Because when you made a profit using 5x leverage, you unfortunately used 10x leverage when losing this time, the overall mathematical expectation will be negative, so try to maintain consistent leverage.
B. When your assets grow to 100k, a 40% drawdown means you lose more money, your resolve is shattered, emotions affect your win rate, and the overall mathematical expectation changes again.
C. Classic mathematical expectation requires a sufficiently large number of occurrences, which means you need a sufficiently long trading career. If you unfortunately fall to a very low asset level, do you have enough time to recover?

Do not get tangled in their claims that the profit-loss ratio must be positive, do not disdain a 1% profit, beating fees, a more stable win rate, and reasonable mathematical expectations are the essence. (This does not mean you shouldn't use stop-losses; try using wider stop-losses.)
