Chinese Stock Screen Using RSI, Best-Level Volume, and Trade-Volume Ratio

Summary

This Chinese-language document describes a stock-selection screen combining a 14-period RSI below 65, first-level bid volume greater than first-level ask volume, and an external-to-internal trading-volume ratio above 1.3. The ratio is approximated from recent volume on rising versus falling candles, smoothed with a five-period moving average. The intended interpretation is that the RSI avoids an overly elevated reading while the volume conditions indicate stronger buying activity.

The page presents formula and Python examples and discusses practical limits: the criteria are narrow, market structure and funding conditions can be hard to predict, and the screen alone cannot assess a stock’s full investment value. It suggests adding other market and fundamental data and adjusting the rules as conditions change. No backtest, portfolio results, or evidence that the filters identify profitable stocks is supplied, so the stated rationale remains a hypothesis. The page does not define position sizing, exits, or a risk-control process in operational detail.

Key ideas

• The screen requires a 14-period RSI below 65.
• It also requires first-level bid volume to exceed first-level ask volume.
• A smoothed ratio of rising-candle volume to falling-candle volume must exceed 1.3.
• The document warns that the three filters offer a narrow view of market and company conditions.
• No backtest or performance evidence is provided for the selection rules.
