A Chinese A-Share Screen Using RSI, Trading Volume Imbalance, and Price

Summary

This document presents a stock-selection screen for Chinese A-shares. It combines RSI below 65, an external-to-internal trading volume ratio above 1.3, and a close above the previous session’s low. The sample screening logic also restricts floating market capitalization to a stated range of 500 million to 2 billion yuan. The post includes example query and Python snippets intended to identify stocks matching these conditions.

The author frames the filters as a mix of technical, trading-activity, and price criteria, and warns that emphasizing short-term price behavior may miss longer-term opportunities and cannot remove market risk. The document gives no backtest, return data, benchmark, or validation of the proposed explanation for the indicators. Its Python calculation for volume imbalance may also differ from the stated external-to-internal ratio, so implementations should be checked carefully before use. It suggests adding other market and macroeconomic measures and reviewing the screen over time.

Key ideas

• The screen combines RSI below 65, a volume ratio above 1.3, and a close above the prior low.
• The example also limits stocks by floating market capitalization.
• The post provides query and Python examples but no performance evaluation.
• The author cautions that the filters do not eliminate market risk and may favor short-term moves.
• The code’s volume calculation should be checked against the stated ratio condition.
