Chinese Stock Screening with Intraday Range and Auction Buying Flow

Summary

This Chinese stock screening note combines a price-range filter, ranking by large-order net volume, buying activity during the opening auction, and a minimum threshold for very large buy orders. It presents these conditions as a way to find active stocks attracting substantial buying interest. The rationale is that a wider range suggests volatility, large-order activity may reflect market participation, and auction buying may indicate sentiment.

The note acknowledges that the screen is technical and flow based, without fundamental analysis, and may perform poorly when market conditions turn adverse. It recommends adding company fundamentals and other indicators, then applying risk controls and position management. It also includes sample indicator and Python references, but their conditions do not fully match the stated screen, so the examples should not be treated as a validated implementation. No backtest, performance evidence, or detailed execution rules are provided.

Key ideas

• The screen combines price amplitude, large-order net volume ranking, and opening-auction buying activity.
• A stated threshold on very large buy orders adds a further flow condition.
• The proposed rationale links price movement and large-order activity to volatility and market interest.
• The approach omits company fundamentals and has no performance evidence in the document.
• The note recommends adding filters and risk and position controls.
