Stock Screening with Price Amplitude, Limit-Up History, and Weekly MACD

Summary

This stock selection method combines three filters: daily amplitude above 1%, at least two limit-up sessions within the prior 500 days, and weekly MACD above its zero line. The article interprets recent limit-up history and amplitude as signs of short-term strength, while positive weekly MACD is intended to identify a longer-term upward trend. It defines the MACD condition using positive DIF, DEA, and histogram readings and includes a Python example as a rough implementation reference.

The document provides no backtest, performance statistics, or comparison with alternative filters. It warns that MACD can produce false signals, that a weekly zero-line filter may exclude some promising shorter-term stocks, and that technical-only selection can omit fundamentally strong companies. It suggests adding financial measures such as valuation, revenue, and profit, as well as other technical filters. The code should be treated cautiously: its amplitude test uses an average, and its limit-up and weekly MACD checks may not precisely implement the stated screening rules.

Key ideas

• The screen requires amplitude above 1%, at least two limit-up days in 500 days, and positive weekly MACD components.
• The method combines short-term price strength with a longer-horizon trend filter.
• The article identifies false MACD signals and the risk of excluding shorter-term opportunities.
• It recommends including fundamental measures, but reports no backtest or performance evidence.
