Chinese Stock Screening with Auction Buying and Large-Order Flow
Summary
The document describes a Chinese equities screen combining price amplitude above 1, circulating market value above 100 billion yuan, positive buying pressure in the opening auction, and combined buying volume from the first two bid levels above 0.7 ten-thousand units. Its rationale is to select larger, active stocks where auction order flow suggests buying interest. It also sketches how market data fields and a Python data workflow could be used to identify qualifying stocks.
The author warns that short-term trading signals may capture speculation while overlooking valuation, business quality, and other long-term factors. Auction orders can also give a misleading picture of demand. Suggested refinements include adding valuation and profitability factors, technical indicators, and more information about buyers and sellers. The examples are implementation references rather than evidence of historical performance: the document gives no backtest results, execution rules, or risk-adjusted returns, and its code descriptions do not fully align with every stated screen condition.
Key ideas
- The screen combines stock amplitude, circulating market capitalization, and opening-auction buying pressure.
- It uses buying volume at the first two bid levels as an additional order-flow condition.
- The approach focuses on short-term trading activity and may miss valuation or business-quality considerations.
- Auction order flow can be misleading, so the screen may benefit from additional factors and buyer-seller context.
- The document provides code references but no performance evidence or detailed execution rules.
