In trading, technical skills are only the foundation; mindset is the dividing line. When in floating profit, you cannot bear to lock it in, watching your gains disappear bit by bit; after suffering losses, you stubbornly hold on, always hoping for a miracle. I believe many people lose not to the candlestick chart, but to their own inner demons. Learn to accept stop-losses and accept being wrong, and abandon the fantasy of getting rich overnight. First stabilize your mindset, then talk about profits.
