Treat the K-line chart as a shelf, treat the rising and falling market as a flowing source of customers, and treat each transaction as an inventory adjustment - this is a trader's unique "business philosophy".
Here, there are no obscure technical analysis terms, only "supermarket store manager"-style practical records: How to make a "purchasing list" before the market opens? How to "clear inventory" and stop losses in the face of volatile market conditions? How to adjust shelves (positions) when encountering sudden "peak traffic" (surge/slump)? After the market closes every day, review profits and losses like a supermarket revenue review, and summarize trading strategies like a record of best-selling products.
This is not a textbook, but a trading diary with fireworks: the heartbeat speeds up when staring at the screen, the annoyed review after making a wrong decision, the secret joy when making a small profit, and the patience and wisdom to "manage" trading as a lifelong career.
Perhaps one day in the future, when their children open it, they will see not only the rise and fall of the K-line, but also the survival logic of an ordinary person using supermarket thinking to fight against the chaos of the market - about the weighing of risks, about the restraint of desires, and about finding a certain way of doing business amid uncertainty.
