Auction Activity and Order Flow Filters for Chinese Stock Selection

Summary

This post describes a Chinese equity screening idea that combines intraday price range, opening-auction activity, and buying by large orders. It proposes selecting the five stocks with the highest auction turnover among those whose amplitude exceeds one, then requiring large and very large order buying to exceed a stated threshold. The post later adds valuation limits, accelerating volume, and a price-above-moving-average condition.

The rationale is that a wide range and high auction turnover indicate activity, while large-order buying may suggest capital inflows. The document offers formula and Python-style examples, but no historical test, performance results, or precise validation of the data fields. It acknowledges that order flow can reflect shifting sentiment and that the initial screen omits company fundamentals. The suggested additions are presented as possible refinements, not as tested improvements; the strategy’s practical value and robustness are therefore undemonstrated.

Key ideas

• The screen ranks stocks by opening-auction turnover and filters for a minimum price range.
• It uses large and very large order buying as a proxy for capital inflow.
• The proposed version adds valuation, volume acceleration, and moving-average conditions.
• The post provides example formulas but no backtest or performance evidence.
• Order-flow signals can change with market sentiment, and the screen may carry substantial risk.
