牛回头回抽预警：当股价在60日以上周期运行后出现短线回调，即形成经典牛回头形态。这提示了强势震荡行情后的最优买入时机，帮助投资者识别关键入场点。
多维度信号验证：本指标融合均线、开盘价、收盘价及资金动能等多重信号，通过主力与散户资金对比，有效剔除假牛市干扰，精准锁定真实回调机会，提升交易胜率。
可视化提示清晰直观：主图与副图同步标注牛回头标识，无需紧盯指标，界面直观清晰。指标不含未来函数，信号可靠。
核心逻辑解析：趋势基准价格突破4日加权平均价，属于典型短期多头信号。要求至少运行60根K线，确保回调发生在成熟趋势中，增强形态有效性。
蜡烛形态确认：当日开盘价高于前日收盘价，但收盘价低于当日开盘价，形成冲高回落K线形态，进一步确认回调信号。
资金动能监测：通过短期动能比率计算力道线，该线在过去9根K线内从高位回落超70%，表明多头动能松动，回调启动，为买入提供依据。
回调买点捕捉：出现牛回头标记时，说明回调幅度合理，买盘可能介入，适合小仓布局并设置止损，控制风险。
跟踪验证策略：后续2至3日内，若价格守住标记日低点且量能放大，可逐步加仓；若未能企稳则及时止损，保护资金安全。
波段操作思路：建议搭配趋势线或更长周期均线如EMA50使用，把握回调后的延续上涨行情。聚焦强趋势股池，仅强趋势个股存在牛回头机会，趋势疲软个股无需关注。
