A Short-Term Chinese Equity Screen Using MACD, Turnover, and Float Size

Summary

This Chinese-language post outlines a short-term equity screen using three conditions: a shrinking MACD histogram on 15-minute bars, a cap on tradable share float, and high relative trading volume. It ranks stocks by volume ratio, filters for smaller float capitalization, and interprets a contracting negative MACD histogram as a possible short-term rebound signal. The proposed refinement adds RSI above a threshold, price above the Bollinger middle band, and filters for stronger company results and industry prospects.

The post cautions that high inflows, small float size, and a potential rebound signal do not ensure that prices will rise. It suggests combining technical, fundamental, and industry information, but gives no rationale for parameter selection or evidence that the additions improve results. The code excerpt is incomplete, and the document reports no backtest, transaction costs, benchmark, or realized performance. The screen is therefore a candidate for testing rather than a validated strategy, especially given its short time horizon and sensitivity to liquidity and execution.

Key ideas

• The screen ranks stocks by relative volume and filters for smaller tradable float capitalization.
• A shrinking MACD histogram on 15-minute bars is treated as a possible short-term rebound signal.
• The suggested refinement adds RSI, Bollinger-band position, company results, and industry prospects.
• The post warns that flow, small float, and technical signals do not guarantee positive returns.
• The code is incomplete and no backtest or performance evidence is supplied.
