Screening Stocks with Positive MACD, a Price Cap, and Main-Force Signals

Summary

The document outlines an A-share stock screen combining a MACD condition, a share-price ceiling, and a signal described as previous-day main-force control. It says the screen is intended to run before trading and provides indicator-formula references for the MACD, price, and main-force conditions. A Python example sketches how to retrieve price and control data and assemble a list of qualifying stocks, though it also includes moving-average crossover calculations that are not clearly integrated into the stated selection rules.

The article warns that strict filters can exclude otherwise attractive stocks and that the main-force measure may be affected by broad-market moves or news. It suggests adding sentiment or flow measures, relaxing the control threshold, and limiting individual position sizes. The example is not a validated strategy: data interfaces may need adjustment, implementation details are incomplete, and no backtest results or risk-adjusted performance evidence are supplied.

Key ideas

• The proposed stock screen combines MACD, a price threshold, and a prior-day main-force control condition.
• The document provides indicator and Python examples, but the code’s moving-average crossover calculations are not clearly tied to the stated rules.
• Strict screening thresholds can reduce the opportunity set and miss stocks that meet longer-term investment goals.
• The main-force measure may be unreliable when market-wide moves or news affect observed activity.
• The article recommends considering additional market signals and controlling position sizes, but presents no performance validation.
