Chinese Stock Screen Using Intraday Gain, Amplitude, and Weekly MA Cross

Summary

This article describes a Chinese equities screening rule combining three conditions: price amplitude above a stated threshold, the 9:25 price gain below a cap, and a weekly five period moving average crossing above the ten period average. It interprets amplitude as a sign of activity, the early session price move as a short term measure, and the weekly crossover as evidence of a longer trend change. The intended use is a medium term stock selection process. The article also suggests adding indicators such as MACD or relative strength and considering company fundamentals and broad market conditions.

The document includes indicator syntax and a Python example that retrieves stock, tick, and weekly data. However, the sample’s amplitude check does not clearly implement the stated threshold, and its dates and data handling make the example difficult to treat as a reproducible screen. No historical returns, benchmark comparison, or selection results are reported. The risk discussion acknowledges that technical filters can omit fundamental information and remain exposed to company news and large market moves; the screening logic is therefore a hypothesis, not demonstrated evidence of an effective strategy.

Key ideas

• The proposed screen combines price amplitude, the 9:25 price change, and a weekly moving average crossover.
• The weekly crossover is intended to capture a longer trend change, while the early session price change reflects short term movement.
• The author suggests combining technical filters with fundamentals and overall market conditions.
• The example code may not faithfully implement the stated amplitude condition and lacks reproducible performance evidence.
• The article notes exposure to company developments and broad market volatility.
