Screening Stocks for High Intraday Activity and a Rounded Price Pattern

Summary

This Chinese-language post describes an equity screen using amplitude above 1, current trading volume above 10,000 lots, a higher open, and a rounded price pattern. It presents these conditions as signs of active trading and a potentially stable short-term move. The suggested implementation checks price and volume data and attempts to identify the rounded shape by fitting a straight line to closing prices, then comparing average deviations with the average high-low range.

The post cautions that the screen emphasizes short-term price action and omits longer-term trends and fundamentals. It suggests adding technical measures, company fundamentals, and market sentiment, but provides no backtest or performance evidence. Its sample code and shape test are illustrative and may not faithfully implement the stated conditions: in particular, a straight-line fit is not a clear test for a rounded curve, and the volume and opening-condition checks have ambiguities. Treat the rules as a screening idea requiring validation, not as an established strategy.

Key ideas

• The screen combines amplitude, current volume, a higher open, and a rounded price shape.
• The post associates high amplitude and volume with active trading, but offers no measured evidence of predictive value.
• Its sample shape test fits a line to closing prices and checks average deviations against the average daily range.
• The author notes that short-term rules omit longer-term trends and fundamental information.
• Additional technical, fundamental, and sentiment measures are proposed as possible filters.
