A Short-Term Stock Screen Using Volatility, Strength, and the Ten-Day Average

Summary

This proposed screen looks for non-ST Chinese stocks before 10 a.m. with amplitude greater than one, a pattern described as a five-step limit-up method, and an opening price near the ten-day moving average. The accompanying example translates parts of that description into data filters: it measures amplitude using high, low, and previous close; excludes names containing ST; selects records before 10 a.m.; and checks recent closes against a five-day average. It treats an opening price within five percent of the ten-day average as “near.”

The article frames the conditions as a short-term, technically driven selection approach, but its label for the limit-up method is not clearly defined by the supplied explanation. The example uses a five-day average rule as a proxy, which may not capture a distinct limit-up pattern. No backtest or outcome data are provided. The author notes that financial fundamentals and industry context are omitted and suggests adding measures such as valuation and leverage.

Key ideas

• The screen combines amplitude, exclusion of ST-designated stocks, a pre-10 a.m. timestamp, a five-step pattern, and proximity to the ten-day average.
• The example calculates amplitude from intraday extremes and the previous close.
• It uses five consecutive closes at or above a five-day average to operationalize the stated pattern.
• Opening-price proximity is defined in the example as within five percent of the ten-day average.
• The article provides no performance evidence and flags missing fundamental and industry analysis.
