A Short-Term Stock Screen Using Amplitude, Large-Order Flow, and K-Line Conditions

Summary

This Chinese stock-selection note describes a technical screen combining price amplitude above 1, a ranking by large-order net volume, and a K-line condition below 20. The stated intent is to find active stocks and short-term trading opportunities. The article includes sample indicator logic and Python-style selection steps, but the examples do not clearly implement the headline strategy: the sample code tests a price-to-earnings threshold instead of ranking large-order net flow, and its K-line condition is not fully explained.

No backtest, return data, or other evidence is given to show that the screen works. The note warns that short-horizon signals can lag or fail when market conditions change, and that the approach leaves out fundamentals and risk controls. It proposes adding other technical and fundamental measures, adjusting conditions as markets change, and using position sizing to limit exposure. Because the written rules and code are inconsistent, the screen would need precise definitions and careful validation before it could be evaluated as a strategy.

Key ideas

• The stated screen combines amplitude above 1, a large-order net-volume ranking, and a K-line value below 20.
• The article presents the method as a way to identify active stocks for short-term trading.
• The sample code does not fully match the headline rules, including substituting a valuation condition for large-order flow.
• The note provides no performance evidence and warns that short-term indicators can lag or fail.
• It recommends adding risk controls, position management, and other analytical inputs.
