Screening Chinese Equities by Intraday Flow and Price Conditions

Summary

The proposed stock screen combines three daily conditions: price amplitude above one percent, afternoon large-order net inflow, and a closing price above the prior day’s low. It then selects the candidate with the highest gain. The article gives indicator formulas and sample code references, presenting the rules as a short-term way to identify volatile shares with buying flow and a price that has held above the previous session’s low.

The author cautions that the screen focuses on short-term price action and capital flow, omitting company fundamentals and longer-term prospects. Selecting the strongest gainer may also expose a position to a pullback. Suggested refinements include adding valuation measures, company size, and industry filters. No backtest, performance figures, execution rules, or evidence of predictive value are supplied; the formula and code examples also do not fully establish how the afternoon flow condition is calculated in practice.

Key ideas

• The screen requires daily amplitude above one percent, afternoon large-order net inflow, and a close above the previous day’s low.
• It ranks qualifying shares by gain and favors the strongest performer.
• The rules target short-term price and flow behavior without a fundamental assessment.
• The article identifies pullback and screening risks but provides no backtest evidence.
