A-Share Screening with Amplitude, Control Data, and Morning-Star Signals

Summary

This post presents a Chinese stock-selection screen using daily amplitude, a measure described as current control above 21%, and a morning-star signal attributed to Kute Intelligent. Its discussion characterizes the setup as a short-term technical approach and says the morning-star indicator uses opening, closing, high, and low prices. The provided formula and Python example, however, operationalize the final selection with amplitude, control-shareholder change, and positive money-flow categories, rather than clearly implementing the named morning-star condition.

The author suggests combining the signal with other technical indicators or event information for a fuller assessment. The post offers no historical test, performance results, or validation of the indicator. It cautions that short-term moves can be affected by unpredictable events or manipulation and that an OHLC-based indicator cannot represent all market conditions. The mismatch between the stated screen and sample code is a key implementation limitation; researchers would need to define and verify each condition before testing the idea.

Key ideas

• The stated screen combines amplitude, a control-related measure, and a morning-star signal.
• The sample formula and Python code instead use money-flow conditions, so they do not clearly match the stated setup.
• The post proposes adding technical indicators and event information, but reports no validation or performance evidence.
• Short-term price moves and an OHLC-only signal can leave important risks unmeasured.
