The entry point for investment relies on technical analysis, while the entry point relies on mentality,Position management and luck, while the emergence, maintenance, and expansion of profits rely on moving stop loss and take profit. Trading is a skill, an ability, not just knowledge! Just like driving or swimming, mastering this skill through theoretical research is not feasible. It can only be mastered through long-term and extensive practice. A person who studies various trading theories all day but lacks trading practice is as ridiculous as a person who reads swimming books all day but dares not go into the water.
