Screening Stocks by Intraday Range, Convertible Bonds, and Auction Buying

Summary

This Chinese equity screening proposal combines an intraday high-low range of at least 1%, a nonempty name for an outstanding convertible bond, and positive net buying attributed to major participants during the opening auction. The accompanying indicator example further describes an up session and stronger bid than ask volume. The article interprets the range as a sign of elevated price movement, the bond field as a company-related filter, and auction buying as a measure of market interest. It suggests adding valuation and fundamental criteria to reduce speculative selections.

No historical test or performance evidence is supplied. The article acknowledges that the rules may overlook company fundamentals and select low-quality or short-term speculative stocks. Its Python example introduces additional filters, including a moving-average comparison and a dividend condition, that do not cleanly match the stated screen; it also relies on data fields and calculations whose definitions are not established in the text. The proposal is therefore best treated as an initial screen, with inputs, timing, and every added condition verified before research use.

Key ideas

• The proposed screen combines a minimum intraday range, an outstanding convertible-bond name, and positive auction net buying.
• The indicator example additionally refers to an up session and bid volume exceeding ask volume.
• The article advises adding valuation and fundamental measures to address risks from sentiment-driven selection.
• No test results are presented to establish the screen's effectiveness.
• The Python example adds conditions that do not clearly match the stated rules and needs careful review.
