Combining RSI, Consecutive Down Days, and Limit-Up Signals in Chinese Stocks

Summary

This article outlines a short-term Chinese equity screen using RSI below 65, three consecutive declining sessions, exclusion of ST-designated stocks, and a condition related to trading halts during the first ten minutes after the open. It then proposes applying a five-part limit-up method to identify candidates thought more likely to reach the daily price limit. Formula and Python examples accompany the description, but they do not clearly define the five-part method or provide a reproducible, stock-specific probability estimate.

The article cautions that technical and limit-up signals can be inaccurate or delayed, and that a focus on short-term price action and sentiment leaves fundamentals and longer-term trends underrepresented. It recommends considering fundamental and market conditions, alongside possible model-based optimization. No backtest or performance evidence is supplied. The example code also appears to use forward prices in its limit-up calculation, which could introduce look-ahead bias if used for historical selection; its trading-halt and candle conditions would need careful verification before use.

Key ideas

• The proposed screen combines a sub-65 RSI, three declining sessions, non-ST status, and an opening-period halt condition.
• A five-part limit-up method is added to rank candidates, but its calculation is not explained in sufficient detail.
• The article acknowledges that short-term technical and sentiment signals can fail and omit fundamental context.
• No backtest results are presented, and the example limit-up calculation appears to reference future prices.
