# This is the stock selection criteria

**The only criterion for judging "whether to buy": Trend structure**

Don't look at "percentage gain", look at these 3 **structural signals**:

1.  **Whether moving average support is effective**: Is the stock price still running above the 10-day (or 20-day) moving average? Does it hold every time it pulls back?
2.  **Whether the price-volume relationship is healthy**: Does it rise on volume? Does it pull back on low volume? If so, it indicates orderly capital flow, not distribution.
3.  **Whether there is "accelerating to the top"**: Only when the stock price shows **consecutive large bullish candles, rapidly moving away from the moving average** (e.g., bias ratio \> 15%), accompanied by huge volume, is it a danger signal.

**Core logic**: If a stock can rise along the 10-day moving average, it indicates **extremely high control by major funds, and profit-takers are not eager to cash out**. This is often the **early characteristic of a main upward wave**, not the end.
