A-Share Limit-Up Strategies and Backtest Execution Constraints

Summary

This discussion distinguishes two approaches to Chinese A-share limit-up trading: a daily model that forecasts which stocks may hit the limit the next day, and an intraday model that uses current market information to identify candidates for the remainder of the session. It suggests momentum features such as rolling returns, rolling trading volume, MACD, and RSI, while noting that quantitative methods can be applied to either whole-market or individual-stock analysis.

The main backtesting lesson is that a stock already at its price limit may be impossible to buy, so a simulation should account for failed orders or uncertain fill probability. It also recommends defining take-profit and stop-loss levels given the strategy's risk. The material is conceptual guidance, not a tested strategy: it offers no thresholds, measured fill rates, or performance results. A robust implementation would need realistic order and fill modeling alongside evaluation of its exit rules.

Key ideas

• Limit-up forecasting can use daily predictions or intraday signals for the remainder of a session.
• Suggested features include rolling returns, rolling volume, MACD, and RSI.
• Backtests should model the possibility that orders cannot fill once a stock reaches its price limit.
• The discussion recommends defining take-profit and stop-loss rules for this high-risk approach.
• It provides no tested parameters or empirical performance evidence.
