Screening for High Amplitude, Turnover, and Weekly Uptrend Signals

Summary

This Chinese equity screen looks for stocks with price amplitude above 1, prior-day actual turnover between 3% and 28%, and a bullish weekly chart pattern. The article’s example defines the weekly condition with rising moving-average alignment, price above an upper volatility band, and additional comparisons among moving averages. It includes sample formula and Python implementations, but does not present historical results, a benchmark, or evidence that the conditions improve returns.

The method combines volatility, trading activity, and trend filters, and the article characterizes it as potentially short-term and speculative. It cautions that a bullish weekly pattern does not guarantee a continuing trend and suggests further technical and fundamental analysis. The sample code and prose do not fully align: the stated prior-day turnover filter is represented in code as a volume ratio, which may not measure turnover as described. The threshold definitions and data handling therefore need validation before use.

Key ideas

• The screen combines amplitude above 1, prior-day actual turnover from 3% to 28%, and a weekly bullish pattern.
• The sample weekly pattern uses moving-average relationships and a volatility-band condition.
• The article offers example code but no backtest or performance evidence.
• The code appears to substitute a volume ratio for the stated turnover measure, so implementation details need checking.
