Screening Stocks by Price Range, Large-Order Flow, and Recent Limit-Ups

Summary

This document presents a technical stock-screening idea for Chinese equities: select stocks with an amplitude threshold, rank by large-order net volume, and require a limit-up event within the previous month. It interprets wide price movement as a sign of volatility, large-order flow as a measure of trading activity, and a recent limit-up as evidence of market attention. Example formula and Python-oriented material are included, although the implementation uses several additional indicator and price conditions that do not clearly match the headline screen.

No backtest or performance evidence is provided, so the suggested potential for strong gains remains unverified. The article notes that the method omits company fundamentals and may expose users to sharp declines, crowded buying, and concentrated positions. It recommends considering fundamentals, other technical measures, market conditions, and risk controls such as position management. The described conditions are therefore best understood as a screening concept rather than a complete or validated trading strategy.

Key ideas

• The proposed screen combines price amplitude, large-order net flow, and a recent limit-up event.
• The article treats these features as signs of volatility, activity, and market attention.
• The sample implementation includes additional indicator and price tests beyond the headline conditions.
• The method provides no reported backtest results and does not establish predictive performance.
• The article flags fundamental, drawdown, crowding, and position-concentration risks.
