My money-losing tool, starting today, I will keep a trading journal to deepen my impression. Don't let a moment of impulse cloud my judgment; all analysis and strategies just fly out the window when I start losing money. When I make money, I get carried away. This is the third time I've been slapped in the face. Luckily, my principal is still intact, but it means I wasted half a month of effort. My position multiplied five times, but all of it was returned in one night. Time to get to work, delivering food. I haven't placed any orders these past two days; I'll wait until Monday! My dad told me something very mystical, but I never took it to heart. He just educated me again. Buy in the first few days of the month, clear out a few days before the end of the month. Buy on Monday, clear out on Friday! Only in this way can I proceed steadily! An uneducated, half-blind old man is still better than me.
