Chinese Stock Screening with Volatility, Moving Averages, and Big-Order Flow

Summary

This stock selection idea combines three filters: amplitude above 1, an opening price near the 10-day moving average, and a positive ranking or reading for net large-order volume. The accompanying examples define the moving-average zone as within five percent of the average and estimate net buying by comparing up-day and down-day volume over a recent five-session window. The intended rationale is to find shares with meaningful price movement, prices near a short-term reference level, and signs of active buying.

The article warns that large-order flow can be unstable and affected by individual trades, while volatility depends on overall market conditions. It recommends combining the signals with company fundamentals, industry trends, and market style. The examples are illustrative rather than a rigorous test: no backtest results, transaction costs, or evidence of predictive value are supplied. The text also describes the moving-average condition as indicating relative stability, an interpretation that the screen itself does not establish.

Key ideas

• The screen requires amplitude above 1, an opening price near the 10-day moving average, and positive large-order net flow.
• The code examples define the moving-average zone as within five percent of the average.
• The examples estimate net flow from up-day and down-day volume over five sessions.
• The article notes that flow and volatility signals can be unstable and recommends adding fundamental and industry context.
• No backtest or performance evidence is presented.
