Combining Volume, Limit-Down Pricing, and Moving-Average Filters

Summary

This Chinese equity screening proposal combines three conditions: rank stocks by volume ratio and select the top 100, identify those with the largest absolute gap between the prior day's 9:15 indicative match price and limit-down price, and require the 20-day moving average to exceed the 120-day average. The stated interpretation is that high relative volume may indicate stronger inflows, a limit-down-related price gap may reflect panic selling, and the moving-average relationship points to a rising shorter-term trend.

The document discusses risks for each signal: volume ranking ignores outflows, the limit-down observation may reflect sentiment rather than a change in value, and two moving averages describe only a limited slice of trend behavior. It suggests considering turnover, comparing the price gap with the prior close, and adding other indicators. The proposed final rules are incomplete, and the page provides no backtest evidence or performance statistics, so it does not establish whether the combined screen is effective.

Key ideas

• The screen ranks stocks by volume ratio and selects the top 100.
• It considers the largest gaps between the previous 9:15 indicative match price and limit-down price.
• It requires the 20-day moving average to be above the 120-day moving average.
• The discussion flags flow, sentiment, and trend-measurement limitations.
• The final proposed logic is truncated, and no performance evidence is given.
