Stock Screening with Daily Range, Reversal Patterns, and Positive Returns

Summary

This post describes a Chinese equity screen combining three conditions: daily price amplitude above 1%, a reversal or engulfing-style pattern, and a positive current return. It gives indicator-formula and Python examples for applying the conditions, then suggests adding company and industry research and using risk controls such as stop losses. The post presents the screen as a way to narrow the stock universe, but it does not report a backtest, performance data, or evidence that the filters improve returns.

The method has implementation ambiguities. The text's reversal condition and the Python candlestick-pattern calls are not clearly equivalent, and the code includes an additional pattern calculation that is not used in the final selection. The post also warns that the approach may carry substantial short-term risk and that chasing returns can overlook losses. Its recommendations are general; no position sizing, entry and exit rules, or validation procedure is specified.

Key ideas

• The screen requires daily amplitude above 1%, a reversal pattern, and a positive current return.
• The post provides formula and Python examples, but their reversal-pattern definitions may not match.
• It recommends supplementing technical filters with industry and company analysis.
• The strategy has no reported performance evidence and may expose users to substantial short-term risk.
