Screening Stocks for Volatility and Sustained Large-Order Buying

Summary

This Chinese stock-selection note describes a screen combining daily price amplitude, a prior-day indication of major-player control, and positive net volume from large orders for at least three consecutive days. It presents these signals as a way to find stocks with room to move and continued institutional buying interest. The accompanying example code adds liquidity and valuation-related filters, then checks large-order activity across several days.

The note gives no backtest, performance figures, or evidence that the signals predict returns. It warns that several days of positive large-order flow may arrive after much of a price rise has already occurred, increasing entry risk. It suggests adding trend indicators and company, market, and industry fundamentals for context. The code is illustrative, and its filters do not exactly mirror every condition in the stated screen, so implementation details and data definitions would need review before use.

Key ideas

• The screen combines price amplitude, a prior-day control signal, and several days of positive net large-order volume.
• Large-order flow is treated as a clue to institutional interest, not proof of future returns.
• The note warns that sustained buying may be detected late in a price advance.
• It recommends combining the flow and price filters with trend and fundamental analysis.
