Backtesting First-Limit-Up Trades with Intraday Signals

Summary

The discussion considers how to evaluate a Chinese stock-market tactic that buys during the session as a stock approaches its first daily price-limit rise, then sells on the following day. Because the entry decision happens intraday, it suggests using minute-level backtesting instead of relying on ordinary end-of-day signals.

Possible entry rules include a substantial intraday gain or a sudden increase in volume, intended to identify stocks nearing the limit. Example exits include selling after a weak opening the next day or once a loss threshold is reached. These are illustrative ideas rather than a fully specified strategy: the post supplies no exact thresholds beyond its example, execution assumptions, slippage treatment, historical results, or evidence that the signals predict limit-up moves. A useful evaluation would need to model intraday timing and realistic fills.

Key ideas

• The proposed trade enters intraday as a stock nears its first limit-up move and exits the next day.
• Minute-level data is suggested to represent the timing of the entry decision.
• Intraday gains and sudden volume increases are offered as possible entry signals.
• A weak next-day open or a loss threshold are suggested as exit rules.
• The discussion gives no completed backtest or execution-cost analysis.
