Intraday Stock Screening with Volume Ratio and Shortening MACD Bars

Summary

This Chinese stock-selection post proposes combining three filters: rank stocks by volume ratio and keep the top 100, exclude shares that hit the daily upper price limit the prior day while focusing on stocks that fell, and select stocks whose MACD histogram bars are getting shorter on a 15-minute chart. The author interprets the setup as identifying possible short-term rebounds alongside relative trading activity. The post also suggests considering company fundamentals and industry prospects and checking MACD on longer time frames.

The document does not provide a complete reproducible implementation: its code example is truncated during the prior-day performance filter, and it offers no backtest or performance evidence. It cautions that the screen emphasizes short-term behavior and omits longer-term trends and company fundamentals; weak overall market conditions can also undermine qualifying names. The proposed interpretation of shortening negative MACD bars as a potential rebound signal should therefore be treated as a hypothesis for testing, not a demonstrated return effect.

Key ideas

• The proposed screen ranks stocks by volume ratio and retains the top 100.\nIt focuses on stocks that fell the previous day and excludes those that reached the daily limit-up price.\nA shortening MACD histogram on a 15-minute chart is used as a possible rebound signal.\nThe post offers no backtest, and its code example is incomplete.\nThe author notes that short-term signals omit longer trends and fundamentals and may fail in a weak market.
