Combining Intraday Range, Limit-Down Auctions, and Rising Moving Averages

Summary

This document proposes a Chinese stock screen combining three conditions: an intraday range above 1%, a prior-day 9:15 auction match at the limit-down price, and current moving averages ordered upward across the 5-, 10-, and 20-period averages. The article interprets the range as a volatility filter, the auction condition as a signal of market pressure, and the moving-average ordering as evidence of an upward trend. It also suggests ranking qualifying names by another measure and selecting a chosen number of stocks.

The article cautions that the criteria are limited and that sharp price moves can make moving averages produce false signals. It proposes adding indicators such as MACD and volume, as well as further market analysis. Formula and Python examples are included, but the ranking field is left unspecified and no backtest or performance evidence is presented. The screen therefore describes a candidate-selection hypothesis rather than a demonstrated reversal strategy, and the document notes that practical use may require adjustment to the chosen data and market conditions.

Key ideas

• The proposed screen combines an intraday range above 1%, a prior auction limit-down condition, and rising short-term moving averages.
• The moving-average condition orders the 5-, 10-, and 20-period averages from highest to lowest.
• The author interprets the auction condition as market sentiment and the averages as an upward trend signal.
• The document warns that the screen is narrow and moving averages can give false signals after extreme moves.
• It suggests adding volume or MACD but provides no performance evidence.
