A-Share Screen Using RSI, Trading Pressure, and Shanghai Listings
Summary
The post proposes screening Shanghai-listed A-shares using an RSI below 65 and an external-to-internal trading volume ratio above 1.3. Its example also filters out stocks whose current price change is at or below negative 3 percent. The stated rationale is to combine a technical condition with a measure of buying versus selling activity, while limiting the universe by exchange listing and excluding sharp current declines.
The article suggests adding valuation, industry, and market context, but it provides no backtest, return statistics, or evidence that the rules predict future performance. Its code reference mixes data retrieval and filtering, and the described conditions are not fully consistent across the post: some passages omit the price-change filter, and the heading does not specify the same ratio threshold as the main strategy description. Treat it as an informal screening idea that needs precise definitions and out-of-sample testing.
Key ideas
- The proposed screen requires RSI below 65 and an external-to-internal trading ratio above 1.3.
- It restricts eligible stocks to codes beginning with 60, corresponding to Shanghai listings.
- An example adds a filter excluding stocks with current price declines of 3 percent or more.
- The post offers no performance evidence, and its rule descriptions are not fully consistent.
- Valuation, industry, and broader market factors are suggested as possible additional checks.
