Screening Chinese Stocks with RSI, Three Candles, and a Daily Drawdown Band

Summary

This Chinese equity screening rule combines a 14-period RSI below 65 with a condition described as three consecutive down candles and an intraday low 4% to 5% below the prior day’s high. The document provides example indicator expressions and a Python-style implementation that returns stocks meeting the filter. It frames the approach as a short-term technical screen rather than a complete trading system.

The article offers no backtest, transaction-cost analysis, or evidence that the filter predicts returns. Its accompanying risk discussion warns that relying on a narrow set of technical signals can miss market sentiment and may select speculative names; short-term effectiveness may vary across market conditions. There is also a potential ambiguity: the sample expressions compare prior closes above prior opens, which normally represents up candles rather than down candles, and use an absolute price difference for the drawdown condition. These implementation details should be resolved before interpreting or testing the stated rule.

Key ideas

• The screen combines a 14-period RSI threshold with a three-candle condition and a 4% to 5% price-move band.
• The article supplies sample formulas and a stock-filtering function.
• It cautions that a narrow technical screen may overlook sentiment and can perform inconsistently.
• The sample candle comparisons appear inconsistent with the description of consecutive down candles.
