Technical Stock Screen Using Intraday Timing, Amplitude, and Price Patterns

Summary

This note outlines a Chinese equity screen combining price amplitude above 1, exclusion of ST-designated stocks, selection before 10 a.m., a five-session price-pattern condition, and seven consecutive declining sessions. It provides formula and Python examples, but their definitions are not fully consistent: the stated seven-day low check may be impossible as written, and the code’s amplitude threshold is applied to an absolute price amount rather than the prose’s apparent percentage measure. The five-session rule is also described vaguely as a limit-up method.

The author frames the approach as a short- to medium-term technical screen and notes that it can overlook company financial and operating fundamentals. Consecutive declines may also lag fast-changing markets. Suggested additions include industry and valuation analysis and confirmation with other technical indicators. No backtest or performance results are presented, and the selection logic needs clarification before implementation.

Key ideas

• The proposed screen combines amplitude, exclusion of ST stocks, a five-session price condition, and a seven-day decline pattern.
• The note says selection should occur before 10 a.m., but gives little detail on how intraday data is handled.
• The formula and sample code contain ambiguous or inconsistent definitions of amplitude and the seven-day low condition.
• The author warns that the approach omits company fundamentals and that consecutive-decline signals can lag.
• No empirical performance evidence is supplied.
