3. Trading Discipline

[Capital Allocation] Must be cautious, with a single investment risk accounting for no more than 5% of total funds for maximum safety.

[Stop loss is the bottom line] No matter what, a stop loss order must be placed. This is not caution; it is the only way to continue playing alive.

[Keep the Rhythm] If the key position holds, you might consider going long. If it falls below the key position, it may continue to decline afterwards.

[Flexible Response] Market conditions can change in the blink of an eye; this article only offers a static assessment. When it comes to real money, one must keep an eye on the K-line and be ready to adjust their thinking at any moment.
