Chinese Stock Screen Using Intraday Range, Auction Rank, and Price Position

Summary

This post describes a Chinese equity screening idea that combines a daily range threshold, a top-five ranking by the day’s auction amount, and a condition labeled as prior-day main-force control. The accompanying indicator formula defines that last condition as the close sitting at least 60% of the way from the low to the high. The post argues that range and auction activity capture stock activity, while the closing position may indicate buying interest.

It includes a brief rationale, sample indicator and Python snippets, and general suggestions to add fundamental, industry, or financial measures. It provides no backtest, performance evidence, or validation of the claimed signal. The Python example’s conditions do not cleanly match the stated auction ranking and prior-day timing, and its range test differs from the headline criterion. The post itself warns that the approach is simple, sentiment-driven, and omits company fundamentals, so the screen should be treated as an unvalidated idea rather than evidence of investment value.

Key ideas

• The proposed screen combines a range filter, a top-five auction-amount rank, and a price-position condition.
• The indicator formula treats a close in the upper 40% of the day’s range as satisfying the stated control condition.
• The rationale links trading activity and closing position with market interest, but supplies no empirical validation.
• The post recommends considering fundamentals and industry context alongside technical signals.
• The sample Python conditions do not fully implement the described ranking and timing rules.
