A Stock Screen Combining Moving Averages, Indicator Crossovers, and Buying Activity

Summary

This Chinese-language post proposes screening A-share stocks using three conditions: buying activity above a stated threshold, simultaneous bullish crosses in three technical indicators, and a 20-day moving average above the 120-day moving average. It interprets these filters as signs of capital inflow and an upward trend, while warning that attention or excessive optimism can also increase risk. The accompanying example mentions moving averages and RSI, but its sample conditions do not clearly implement all the stated crossover and buying-activity requirements.

The post suggests adding indicators, market conditions, company characteristics, and industry factors to refine the selection. It supplies no backtest, portfolio results, or evidence that the filters predict returns. The screen is therefore a strategy idea rather than a validated method, and the logic would need to be specified consistently and tested with suitable data before practical use.

Key ideas

• The proposed screen combines buying activity, bullish indicator crosses, and a short moving average above a longer one.
• The post interprets these conditions as signs of inflows and upward momentum.
• It warns that heavy attention and excessive optimism may also carry risk.
• The example code does not clearly match every condition in the described screen.
• No backtest or performance evidence is presented.
