Stock Screen for Intraday Range, Three Limit-Up Sessions, and Turnover

Summary

This Chinese stock-screening proposal selects shares with a daily high-low range greater than 1, a three-session limit-up streak ending the previous day, and turnover between 3% and 12%. The article interprets range as a measure of volatility, the repeated limit-ups as a sign of market attention, and turnover as a measure of trading activity. It presents indicator and Python examples, but no backtest, sample results, or performance evidence.

The post cautions that a screen focused on activity and recent price strength may overlook fundamentals and valuation, may capture short-lived themes, and may narrow the opportunity set too much. It suggests adding trend indicators, industry and market context, volume ratios, or fund-flow measures. The examples should be checked before use: the Python snippet fetches a futures contract despite the article describing stocks, and its limit-up test does not clearly verify three consecutive limit-up closes. As presented, this is an unvalidated screening concept, not a demonstrated trading strategy.

Key ideas

• The proposed screen combines a high-low range above 1, a prior three-session limit-up streak, and turnover from 3% to 12%.
• The article associates these conditions with volatility, market attention, and trading activity.
• It warns that activity-based screening can miss fundamentals, valuation, and short-lived market themes.
• The examples contain implementation ambiguities, including a futures data source for a stock screen.
• The post supplies no performance results and suggests adding broader market and technical context.
