The root cause of failed trades is usually not a lack of technical analysis skills, but an inability to properly handle uncertainty. Most traders always want to predict the market and prove they are right, which leads to fear, greed, hesitation, doubling down, or taking profits too early. But the market is fundamentally a game of probabilities; no single trade can guarantee an outcome. Truly excellent traders are not the ones with the most accurate predictions, but those who can accept that every trade might result in a loss and strictly follow their rules. The highest level of trading is to develop a "probability mindset": believe that your trading system is effective in the long run, rather than obsessing over individual wins or losses. When traders stop trying to control the market and instead focus on controlling their own behavior, consistent profits become possible.
