Opening-Market Stock Screen Using Volume, Amplitude, and a Price-Gain Cap

Summary

This Chinese equity screen looks for stocks with price amplitude above 1, current volume above 10,000 lots, a higher opening price, and a gain below 6% at 9:25. The article frames amplitude and volume as signs of trading activity and treats the capped early gain as an additional filter. It includes a formula and a Python-oriented example intended to identify qualifying stocks from market data.

The article does not provide backtest results, performance statistics, or evidence that the selected conditions predict further gains. It acknowledges that the rule uses few indicators, may miss the effect of broader market conditions, and should be supplemented with company fundamentals, market context, or technical indicators such as MACD and KD. The described criteria are a stock-selection filter, with no explicit entry, exit, or position-sizing method, so they do not constitute a complete trading strategy on their own.

Key ideas

• The screen requires amplitude above 1 and current volume above 10,000 lots.
• It selects stocks that open higher and have a 9:25 gain below 6%.
• The article interprets volume and amplitude as indicators of trading activity, without presenting supporting tests.
• It recommends considering company fundamentals, broader market conditions, and additional technical indicators.
• The screen does not specify trade exits or position sizing.
