A-Share Screen Using RSI, Order-Book Volume, and a 30-Week Average

Summary

This A-share stock screen combines three conditions: a 14-period RSI below 65, first-level bid volume greater than ask volume, and the weekly close crossing above its 30-week moving average. The article interprets the RSI as a measure of price conditions, the bid-to-ask volume comparison as a sentiment cue, and the moving-average cross as evidence of a longer-term upward trend. It also includes illustrative indicator and Python implementations.

The article offers no backtest or performance evidence. It cautions that the screen omits company fundamentals and that buying after a long-term moving-average cross may mean chasing a move with less upside remaining. It suggests adding fundamental and broader market analysis, and checking multiple moving-average periods to reduce reliance on a single signal. The code examples are references; the article does not establish that their data handling or implementation produces a validated trading system.

Key ideas

• The screen requires RSI below 65, bid volume above ask volume, and a weekly close crossing above its 30-week moving average.
• The article treats the RSI and moving-average conditions as technical filters and the order-book volume comparison as a sentiment signal.
• The strategy is a stock selection method and does not provide rules for position sizing or exits.
• The article warns that excluding fundamentals and buying after a trend cross can create risks.
• It recommends combining multiple time horizons and fundamental analysis with the listed conditions.
