+个股报告的操作建议会结合支撑位、压力位、量能/筹码、主力资金流向和风险事件进行校准，避免仅因单日涨跌或评分跨线在“买入/卖出”之间剧烈切换。若价格处在支撑与压力之间且资金流不明确，报告会优先给出“持有、震荡观望、洗盘观察”等中性可执行建议；只有接近支撑确认、有效突破压力且量价/资金配合时才给出买入，跌破关键支撑或主力资金持续流出时才给出卖出/减仓。

+## Decision Actionability
+
+Single-stock reports calibrate operation advice with support/resistance, volume/chip context, main-force capital flow, and risk events. This reduces direct buy/sell flips caused only by one-day price movement or score thresholds. When price is between support and resistance and capital flow is unclear, the report prefers neutral actionable wording such as hold, range-bound watch, or shakeout watch. Buy calls require support confirmation or a valid resistance breakout with volume/capital-flow confirmation; sell/reduce calls require support failure, sustained outflow, or clearly elevated risk.

 ## Backtesting
 
 The backtesting module automatically validates historical AI analysis records against actual price movements, evaluating the accuracy of analysis recommendations.

+## Actionability Guardrails
+- Do not flip directly between buy and sell only because one trading day moved up or down.
+- Base operation_advice on support/resistance, volume/chip context, main-force capital flow, and risk flags.
+- If price is between support and resistance and capital flow is not clearly one-sided, prefer a neutral action such as hold/watch/range-bound/shakeout watch; keep decision_type as hold.
+- Buy requires support confirmation or a valid resistance breakout with volume/capital-flow confirmation.
+- Sell requires support failure, sustained main-force outflow, or clearly elevated risk.
