A Chinese Stock Screen Using Intraday Range, Listing Age, and Opening Move

Summary

This Chinese stock-selection post describes a screen requiring a daily high-low range above 1%, a listing history longer than one year, and a gain below 6% at 9:25 a.m. The stated rationale is to seek active shares while excluding newly listed companies and stocks with especially strong early moves. The post includes indicator logic and a Python example that retrieves market data and filters candidate stocks, although the example also starts from a large-capitalization subset and its data fields and time handling may not precisely match the stated screen.

The author warns that the criteria omit fundamental information, may miss stocks that surge later in the session, and depend on timely market data. The post suggests adding valuation or technical filters and considering price behavior at other times. It supplies no backtest, performance evidence, or detailed validation of the code, so the proposed rationale should be treated as a screening hypothesis rather than demonstrated trading edge.

Key ideas

• The screen combines a daily range threshold, more than one year since listing, and a limited early-session gain.
• The stated intent is to find active established stocks while filtering out large opening advances.
• The included Python example first narrows candidates by market capitalization, so its implementation is not identical to the three stated criteria alone.
• The post notes that the screen ignores fundamentals, may miss later-session surges, and depends on timely data.
• No backtest or evidence of profitability is provided.
