🌟 为什么你总在“抄底”后还跌？因为缺这根“分水岭线”
很多人以为背离就是“KDJ金叉+股价新低”，其实漏掉了最关键的一环：趋势锚点。这个指标里的“分水岭”，不是普通均线，而是动态修正的“多空生命线”——它会自动识别17日均线的“脾气”：涨时加力，跌时托底。当股价站上它，就像踩上自动扶梯；跌破它，哪怕MACD红柱再长，也得先系好安全带。正如交易老手常说：“均线是路，分水岭是桥——没桥的路，走着走着就掉河里了。”
🧩 适配指南：别硬套！这指标专治三类“纠结型选手”
✅ 适合新手：所有信号用颜色+图标直给（红箭头=买、绿虚线=支撑、★M/◎K/◆R=三重确认），不用盯参数；✅ 适合波段党：对“小盘成长股+次新股”响应最灵敏（因波动大、背离真）；✅ 适合耐心型选手：不追涨停、不搏连板，专等“股价创新低但指标不新低”的那一口甜。⚠️ 注意：大盘蓝筹（如银行、石油）慎用——节奏太慢，容易错过卖点；ST股直接拉黑，背离常失效。
