Combining Turnover, Prior-Day Leaderboard Activity, and a Moving-Average Breakout

Summary

This Chinese stock-selection screen combines a turnover-ratio band, a flag for appearing on the previous day’s trading leaderboard, and a moving-average crossover. The stated selection rule requires turnover between 3% and 12%, prior-day leaderboard activity, and a weekly close crossing above its thirty-week average. The accompanying discussion frames turnover and leaderboard presence as measures of trading activity, with the average crossover intended to identify an upward trend.

The document includes formula and Python examples, but their calculations compare close prices with rolling thirty-period averages and also compare close with a rolling average of volume. Those expressions do not clearly implement the stated weekly close versus thirty-week price-average rule, so the implementation should be checked before use. The article also notes that its technical filters omit company fundamentals and industry conditions and may misread choppy or reversing markets. It offers no backtest results or evidence of profitability.

Key ideas

• The stated screen combines a 3%–12% turnover band, prior-day leaderboard activity, and a weekly moving-average crossover.
• The article treats turnover and leaderboard appearance as signs of active trading.
• The supplied examples include comparisons against a rolling volume average as well as a close-price average.
• The example calculations should be checked against the stated weekly crossover rule.
• The screen omits fundamental and industry information and may perform poorly in choppy or reversing markets.
