I recently read the sharing of overseas trader Jeff Sun and top Swedish trader Kristjan Kullam ä gi, which is very interesting. 40% of my current strategy comes from working with them Kristjan Kullam ä gi achieved 15th place on Sweden's personal income chart through wave trading, with earning ability certified by the National Taxation Office. His method essentially involves trend tracking, but position management is completely different - some positions quickly exit, reducing holdings by one-third or one-fifth within 3-5 days, Jeff Sun's profit taking strategy is more detailed: within 0-2 days of entering the market, he earns a profit of 2R, or if he still holds the position on the third day, he reduces his position by 33%. The reason is that when the account size is large enough to affect the quality of life, watching the floating profit increase from+500000 to+280000 in one day is emotionally difficult to bear, Why do they prefer this mode? Because we are working on the US stock market, the regularity of individual stock trends is weak, there are many false breakthroughs, and the explosive power is strong - there are many Nasdaq 100 constituent stocks that have doubled, especially in small and medium-sized stocks. Taking profits early sacrifices some upward potential, and in the long run, it may not be worse than tracking commodity trends, Jeff Sun's data supports this point: the highest profit in 2024 was 51R, with 4 transactions exceeding 20R and 11 transactions exceeding 10R, and the highest monthly win rate was only 31.6%, So trend tracking is not about holding on until the end, actively reducing positions in the face of floating profits, it's not about being indecisive, it's about smarter management of drawdown and emotions,
