A Short-Term Momentum Screen Using Limit-Up Days, Amplitude, and RSI
Summary
This A-share screen combines RSI below 65, daily amplitude above 1%, and more than two limit-up days within ten days. The article frames the combination as a way to find stocks with strong recent price action. It describes RSI, amplitude, and limit-up frequency as technical filters, but does not provide a precise trading or portfolio-management plan.
The document includes indicator descriptions and sample code, but presents no backtest results or performance measurements. It warns that technical-only selection can miss changes in company fundamentals, that consecutive limit-ups may reflect speculative flows rather than material business changes, and that a fixed ten-day window may exclude opportunities on other horizons. It proposes adding valuation and fundamental data or using machine-learning methods to refine selection. Some formula and code details are ambiguous, so the examples do not establish that the stated conditions are implemented consistently.
