Intraday Stock Screen Using Range, Opening Move, and Prior Low

Summary

This Chinese equities screen combines three price conditions: daily amplitude above 1, a 9:25 price gain below 6%, and a closing price above the previous day's low. The stated intent is to find stocks with some volatility and strength while avoiding an unusually large opening rise. The article includes indicator and Python examples for applying the filters to listed stocks, including a main-board restriction in its sample code.

The method is a simple short-term screening rule, not a complete trading strategy: it provides no entry timing, exit rules, position sizing, or backtest results. It also cautions that the filters omit fundamentals and longer-term trends, and may not identify popular stocks well. The article recommends considering financial condition, liquidity, market context, and prevailing conditions alongside the price criteria. The code and prose do not align perfectly on the amplitude and opening-price calculations, so reproducing the screen requires clarifying those definitions.

Key ideas

• The screen requires daily amplitude above 1 and a 9:25 gain below 6%.
• It keeps stocks whose close is above the prior day's low.
• The sample code adds a main-board stock restriction.
• The article advises adding fundamental, liquidity, and market-context checks.
