. One break multi: observe at the笔 level, single component strong rebound, the object of destruction can be adjacent笔, can be segments, or can be central, break below now, intervene now, do not wait for a pullback.

2. The extension after one break and one rebound: weak reversal to strong reversal, segment-level judgment, rebound breaks adjacent segments, after the second buy, break through the previous high again for trend confirmation, weak turns strong, break below now, intervene now.

3. The right-side extension of multi-no-break: segment level, rebound does not break the previous high, forming an extension of the previous trend, but the subsequent trend forms a bullish structure of multi-no-break, can intervene at the fixed width of the central three segments or break above, confirm now, intervene now.

This is the method of locking in intervention points based on structural confirmation, targeting the destructive nature of previous trends: greater than, equal to, less than; it is a complete classification. You will not find a fourth situation; this is the application of complete classification thinking and dynamics in practical use.

Learning these things takes less than a minute, but the market is dynamic. Current destruction does not mean extension; it can also reverse the destruction. These are all things you need to respond to dynamically, and responding is the core. This requires you to put in hard work and practice.
