这个指标主要实现三个功能：
支撑阻力计算：通过均价(GJ)公式计算明日支撑/阻力位，并在K线图上标注今日实际支撑阻力区间（如"支/阻"文字提示）。当价格接近支撑位可考虑低吸，接近阻力位注意高抛。
趋势判断信号：
持股：连续3日收盘价创新高时红色标记
变盘：当日最高价创新高且前一日最低价创新低时紫色标记
买入：前一日最低价创新低且当日收阳线时青色标记
抛售：前一日最高价创新高且当日收阴线时白色标记
辅助指标组合：
WR超买超卖：WR上穿-81时提示买入（蓝箭头），下破-19时提示卖出（绿箭头）
均线系统：5日线上穿"垂帘听股"均线组合时提示机会
量价背离：当VC指标超20%且拐头向下时绿色圆点预警
操作策略：
结合支撑阻力位和信号标记操作，如支撑位出现"低吸"信号时买入，阻力位出现"高抛"信号时卖出
持股/买入信号出现且价格在ZARA指标上方时持有，下跌/抛售信号出现时减仓
注意WR指标和量价背离的预警信号，配合使用提高胜率
