MACD and Weekly Candle Filters for Chinese Equity Selection

Summary

This post outlines a Chinese stock-screening idea that combines MACD above zero, a company-type or concept filter, and a weekly bullish-candle condition. It presents the combination as a way to find stocks with positive technical momentum while applying a business classification filter. The accompanying formula references a medical-device concept, while the Python example calculates MACD and aggregates daily prices into weekly bars before applying candlestick-related conditions and ranking results by market capitalization.

The post gives no backtest results or evidence that the conditions predict gains. It cautions that bullish weekly bars can be followed by declines and that focusing on these filters can exclude other promising stocks. It suggests adding valuation, profitability, and other technical measures, tuning thresholds, and considering industry and policy context. The examples also leave implementation details unclear: the company-type description, concept formula, and Python filters are not fully consistent, and the candlestick function used is not clearly equivalent to a generic weekly red-bar signal.

Key ideas

• The screen combines MACD above zero with a company or concept classification and a weekly bullish-candle condition.
• The formula example uses a medical-device concept filter, while the prose describes company characteristics more broadly.
• The Python example aggregates daily prices into weekly bars and applies technical filters before ranking candidates by market capitalization.
• A bullish weekly candle does not guarantee future gains, and the method may miss stocks that fail its narrow filters.
• The post recommends adding fundamental and technical criteria and reassessing the screen as market conditions change.
