Stock Screening with Amplitude, the 10-Day Average, and Arc-Shaped Trends

Summary

This Chinese-language post outlines an equity screening idea combining daily amplitude above 1%, an opening price near the 10-day moving average, and an arc-shaped price pattern. The proposed rationale is to find stocks with meaningful movement that are near a short-term trend reference, then select for a steadier curved price path. It gives example indicator logic for amplitude and a 5% band around the moving average; the arc pattern must be assessed with another tool because the cited platform lacks a built-in indicator for it.

The post does not provide backtest results or define a reproducible method for detecting the arc pattern. It acknowledges that classifying such shapes is subjective and that changes in company fundamentals and market style can hurt performance. It suggests making the pattern definition more precise and combining technical signals with fundamentals, sentiment, and liquidity. The criteria are therefore a rough screening concept rather than a fully specified or validated strategy.

Key ideas

• The screen requires amplitude above 1% and an opening price within roughly 5% of the 10-day moving average.
• The proposed arc-shaped trend criterion has no formal calculation in the post.
• The author views larger amplitude as a source of opportunity, while treating proximity to the moving average as a stability filter.
• Pattern subjectivity and changing fundamentals or market conditions are identified as risks.
