Equity Screening with Price Range, K-Line, and 10-Day Average Filters

Summary

This Chinese-language post presents a stock screening idea based on three conditions: amplitude above 1, a K-line value below 20, and the opening price near the 10-day moving average. It then gives a more detailed indicator example using a curved-line measure relative to its average, the prior opening price versus a 10-day average, and rising volume. The post also includes a Python-style screening example and suggests adding fundamental and market context or other filters such as volume.

The document offers no backtest, performance figures, or precise definition of “near” in its initial description. Its later formula does not map cleanly to all of the headline conditions, and the examples use prior-bar prices and indicator calculations whose implementation details may matter. The author notes that technical-only selection can be unreliable when market conditions change, so the proposed screen should be treated as an illustrative starting point rather than evidence of an effective strategy.

Key ideas

• The initial screen combines an amplitude threshold, a K-line threshold, and an opening price near the 10-day average.
• The later example adds a curved-line indicator condition and requires volume to exceed its prior value.
• The post recommends considering company fundamentals and broader market conditions alongside technical filters.
• No performance evidence is provided, and the headline criteria differ from parts of the example formulas.
