Chinese Stock Screen Combining Volume, Large-Order Flows, and Limit-Ups

Summary

This Chinese stock-selection idea ranks candidates using three signals: volume ratio, net large-order buying, and historical limit-up frequency. The description calls for the top ten stocks by volume ratio and net large-order inflow, alongside stocks that recorded at least two limit-ups within 500 days. The intended interpretation is that these filters may highlight securities attracting attention and capital and showing past bursts of strength.

The article recommends adding market capitalization, industry, and profitability checks, then validating the combined approach with backtests or simulated trading. It offers no results from such validation. Its code is incomplete and does not reliably calculate the described measures: it substitutes unrelated indicators and ends before implementing the selection logic. The stated signals are therefore best read as a rough screening concept, with uncertain definitions and no evidence that the selected stocks outperform. The article also cautions that these indicators alone do not establish investment value.

Key ideas

• The proposed screen combines volume ratio ranking, large-order net inflow ranking, and limit-up history.
• It specifies a top-ten ranking for the first two signals and at least two limit-ups over 500 days.
• The author suggests adding industry, size, and profitability filters and validating the screen through simulation or backtesting.
• The provided code is incomplete and does not faithfully implement the described indicators, and no performance results are given.
