指标是改良版的趋势追踪工具，核心在于捕捉价格的极端反转和背离信号。
主要功能
它在传统波动率指标基础上，增加了直观的强弱分区：零轴上方代表多头强势，下方代表空头弱势。特色功能是自动识别“超卖后回升”的买入点和“超买后回落”的卖出点，并通过底部和顶部的背离信号，提前预警趋势可能发生的逆转。
操作策略
抓反弹：当指标从极低位置向上突破并出现“买”字提示时，说明股价严重超跌后开始转强，是短线抄底良机。
逃顶部：当指标从极高位置向下拐头并出现“卖”字提示时，代表上涨动能耗尽，应果断减仓或离场。
看背离：若股价创新低而指标未创新低（底背离），或股价创新高而指标未创新高（顶背离），往往是趋势反转的确切信号。
