A-Share Screen Combining Range, KDJ Cross, and Intraday Decline

Summary

The document presents a Chinese A-share stock screen requiring three conditions: daily range greater than one percent, a newly formed KDJ golden cross, and an intraday low between four and five percent below the previous close. Stocks meeting the conditions enter a candidate pool. It provides formula examples for an indicator platform and Python-style logic for retrieving and processing daily stock data. The KDJ condition is expressed as the J line moving from below to above the D line, while the decline condition compares the current low with the prior close.

The accompanying explanation interprets range as a sign of volatility and the KDJ cross as a possible improvement in price momentum, but it gives no backtest or evidence of returns. It warns that the screen omits company fundamentals and broader market context, relies on a narrow set of technical conditions, and may expose users to risks associated with special-treatment stocks. It suggests adding fundamental and technical filters and reviewing the candidate universe regularly. The screen is a selection rule, not a complete portfolio or execution strategy.

Key ideas

• The screen combines a daily range threshold, a newly formed KDJ golden cross, and a specified decline from the previous close.
• The selected shares are added to a candidate pool rather than automatically defining a complete trade plan.
• The document supplies indicator-formula and Python-style examples for implementing the conditions.
• The author identifies omitted fundamentals, other market signals, and special-treatment stock volatility as risks.
• No backtest or measured performance is provided.
