A-Share Screening with RSI, Trading-Side Volume, and Beverage Exports

Summary

This screening proposal combines a 14-period RSI below 65 with an external-to-internal trading volume ratio above 1.3 and a beverage or alcohol business linked to imports or exports. The intended idea is to combine a technical condition, a measure related to buying and selling activity, and a narrow business-related filter. The article also discusses using company performance and financial health to broaden the selection process.

The note flags selection bias from a narrow sample, sensitivity of trade-related business factors to macroeconomic conditions, and omission of company results. Its indicator and Python examples offer possible implementations, but they do not establish that the volume ratio is measured reliably or that the conditions predict returns. It reports no backtest, sample performance, or validation method, so the proposal should be treated as an untested screen. The write-up also contains inconsistent technical conditions, including a separate breakout reference in its formula example.

Key ideas

  • The proposed screen combines RSI below 65, a trading-side volume ratio above 1.3, and beverage or alcohol import-export exposure.
  • The author suggests adding company results and financial condition to reduce reliance on a narrow set of filters.
  • The document identifies sample bias and macroeconomic sensitivity as risks.
  • The examples do not provide evidence of predictive performance or a validated measurement of the volume ratio.
