Short-Term Stock Screen Using Daily Range, Prior Control, and Auction Movement

Summary

This note presents a short-term Chinese stock screen requiring an intraday range above 1%, an indication of major-player control on the prior day, and an opening-auction change between minus 2% and plus 5%. The stated premise is to identify volatile stocks with signs of buying interest while excluding auction moves outside the specified band. The article includes a sample filtering approach, but no ready-made formula for the platform’s indicator language.

It offers no backtest or return evidence and acknowledges that short-term price and auction signals can be noisy, while company fundamentals and longer-term prospects are left out. It suggests adding indicators such as MACD or RSI and examining fundamentals and market conditions more closely. The sample code does not clearly align its computed price-change condition with the stated opening-auction interval, so the data definitions and timing would need to be resolved before testing the screen. The method should therefore be treated as a screening hypothesis rather than a demonstrated strategy.

Key ideas

• The proposed screen combines an intraday range threshold, prior-day major-player control, and an opening-auction move within a stated band.
• Its focus is short-term price movement and perceived capital activity.
• The article reports no performance or backtest evidence.
• It warns that brief market signals may be noisy and omit fundamentals.
• The sample implementation’s price-change calculation may not match the stated auction condition.
