A Short-Term Stock Screen Using Intraday Range and Price Gains

Summary

This Chinese equity screening idea targets main-board stocks with an amplitude above 1, an opening auction gain below 6%, and a current-day gain above 1%. It is presented as a short-term approach that looks for shares showing both intraday movement and upward price action. The post includes an indicator formula and a Python example describing how to obtain market data and apply filters.

The post gives no backtest, return series, or evidence that the rules identify profitable trades. Its explanation acknowledges that fast-changing market conditions can make the screen lag or miss opportunities, and that combining range and price gains can produce aggressive selections. It proposes adding company fundamentals, market and industry context, and sentiment measures, but does not define those filters or test whether they improve robustness. The sample code and formula should be treated as illustrations of the stated idea rather than validated implementations.

Key ideas

• The screen combines an intraday amplitude threshold, a cap on the opening auction gain, a positive current-day gain, and a main-board restriction.
• The approach seeks short-term candidates with price movement and upward momentum.
• The document provides sample formula and data-processing logic but no performance evidence.
• It warns that the rules may be aggressive and recommends considering fundamentals and broader market conditions.
