Chinese Stock Screening with Price Amplitude, Large-Order Flow, and Trend

Summary

This document presents a Chinese equity screening idea that combines daily price amplitude, a large-order net-flow measure, and a rising 30-day moving-average trend. Its sample formula checks whether price is above the prior 30-day average, whether the high-low range exceeds a threshold relative to the previous close, and whether a large-order indicator meets a stated cutoff. The Python example sketches a similar screen and sorts candidates by turnover.

The article argues that technical indicators can help assess price, trading activity, and trend, while warning that they reflect historical data and may be unreliable in fast-changing markets. It recommends adding fundamental and industry analysis. No backtest or performance evidence is supplied, and the examples have apparent implementation gaps, including references to helper functions and fields not defined in the excerpt. Universe selection, signal timing, transaction costs, and execution rules are also unspecified, limiting reproducibility and evaluation.

Key ideas

• The proposed screen combines amplitude, a large-order flow measure, and a 30-day trend condition.
• The formula and prose describe a technical stock selection approach, with turnover used for sorting in the example.
• The article provides no backtest or evidence of predictive performance.
• Fundamentals, industry context, market conditions, and implementation details remain important limitations.
