明日抄底指标：支撑阻力计算与趋势信号 源码分享
该指标具备三大核心功能。首先，支撑阻力计算功能通过均价公式预测明日支撑/阻力位，并在K线图上标注今日实际区间，以“支/阻”文字提示。当价格接近支撑位时可考虑低吸，接近阻力位时需注意高抛。
其次，趋势判断信号功能包括：持股信号，连续3日收盘价创新高时以红色标记；变盘信号，当日最高价创新高且前一日最低价创新低时以紫色标记；买入信号，前一日最低价创新低且当日收阳线时以青色标记；抛售信号，前一日最高价创新高且当日收阴线时以白色标记。
此外，辅助指标组合包括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日线上穿均线组合时提示机会；量价背离，VC指标超20%且拐头向下时以绿色圆点预警。
操作策略为：结合支撑阻力位与信号标记操作，如支撑位出现低吸信号则买入，阻力位出现高抛信号则卖出。持股或买入信号出现且价格在ZARA指标上方时持有，下跌或抛售信号出现时减仓。同时，注意WR指标和量价背离的预警信号，以提高胜率。
