Stock Screening with RSI, Bid-Ask Volume, and Recent Limit-Ups

Summary

This Chinese-language post presents a stock screen requiring a 14-period RSI below 65, first-level bid volume greater than first-level ask volume, and at least one limit-up event during the prior 25 days. The conditions combine a momentum-related indicator, order-book volume imbalance, and evidence of a recent large upward move. The post includes formula and code references, but the examples do not establish a validated implementation or demonstrate trading performance.

The author describes the screen as a way to identify stocks with active market interest and favorable recent behavior. Risks include the omission of company fundamentals, financial data, sector conditions, liquidity, and broader market variation. Suggested improvements include incorporating those factors, using multiple selection approaches, and strengthening risk controls and portfolio construction. The document gives no backtest results, comparison with a benchmark, or evidence that the selection conditions produce excess returns, so its rationale should be distinguished from demonstrated effectiveness.

Key ideas

• The screen requires a 14-period RSI below 65 and first-level bid volume above ask volume.
• It also requires at least one limit-up event within the preceding 25 days.
• The post combines price momentum and order-book imbalance with recent price strength.
• The author identifies missing fundamental, sector, liquidity, and risk considerations.
• No backtest or performance evidence is supplied.
