Chinese Stock Screening with Volatility, Ten-Day Returns, and a Rising 30-Day Average

Summary

This stock-screening idea combines three price conditions: daily high-low range greater than one percent of the opening price, a positive ten-day return below 35 percent, and a rising 30-day average. The stated rationale is to find shares with noticeable movement, some recent gains without an extreme run-up, and a favorable trend. A Python example also filters for a closing price above the 30-day simple moving average, then applies a circulating-market-value range and ranks candidates by a flow-related field. These extra steps make the example more specific than the headline screen.

The article provides rules and implementation references but no backtest, return series, benchmark, or evidence that the screen improves outcomes. It acknowledges that simple technical filters can be incomplete and recommends additional indicators, fundamental measures, and risk controls. The criteria are screening conditions, not a complete entry, exit, or position-sizing plan, and the code’s additional filters should be checked against the intended definition of the strategy.

Key ideas

• The core screen requires a daily high-low range above one percent of the open, a positive ten-day return below 35 percent, and an upward 30-day average.
• The proposed rationale combines price movement, moderate recent gains, and trend direction.
• The code example also requires price above the 30-day average and adds market-value and flow-based filters.
• The document supplies no backtest or performance evidence for the screen.
• The rules do not define a complete trading, sizing, or risk-management process.
