A-Share Screen for Positive MACD, Rising Averages, and Prior Limit Down

Summary

This A-share screening idea combines a positive MACD reading, upward-dispersing moving averages on the current day, and a prior-day opening auction match price at the limit down. The document interprets the first two filters as signs of upward momentum and treats the prior limit-down event as a possible rebound setup. Its example code calculates MACD and a five-day moving average, then applies a limit-down filter to historical price data.

The note flags that a stock may remain weak after a sharp decline and that any rebound could be small, leaving an unfavorable risk-reward profile. It suggests adding liquidity or valuation screens and other indicators such as RSI. It supplies no performance backtest, and its prose and code describe the opening-auction condition inconsistently: the explanation refers to a 9:15 match price, while the code uses daily open-price fields. The screen is therefore a candidate-selection concept rather than demonstrated evidence of a profitable strategy.

Key ideas

• The screen combines positive MACD, rising moving averages, and a previous-day limit-down opening match condition.
• The author presents the limit-down event as a possible rebound signal after a severe decline.
• The example computes MACD and a five-day moving average from historical prices.
• The document warns that stocks may continue falling and that rebound gains may not compensate for risk.
