A Chinese Stock Screen Using Turnover, Range, and Rising KDJ

Summary

This post outlines a Chinese equity screen that requires daily amplitude above 1, turnover between 2% and 9%, and a rising KDJ K value. It presents these as technical filters intended to identify stocks showing activity and possible short-term strength. The post notes that the chosen lookback for K-value growth matters and suggests making it adjustable, adding other indicators, and considering broader market conditions.

Indicator and Python examples are included, but the implementation details warrant caution: the Python sample’s turnover calculation and KDJ construction do not clearly align with the stated screen, and it uses a separate market index data call while calculating with stock data. The post provides no backtest, comparison, or measured results. Its own caveats are that technical indicators can miss fundamental information and that KDJ behavior may exclude stocks performing well in sideways markets. The screen is best understood as a proposed filter, not demonstrated evidence of a profitable strategy.

Key ideas

• The proposed screen requires amplitude above 1, turnover between 2% and 9%, and an increase in the KDJ K value.
• The post frames these conditions as a way to focus on active stocks with potential short-term strength.
• It recommends making the K-value growth interval adjustable and considering additional indicators and market context.
• The author warns that technical-only screening can omit fundamental factors and perform poorly in sideways markets.
• The code examples have ambiguities and the document provides no strategy performance evidence.
