买卖信号

该公式不包含任何买卖信号。公式仅计算布林带（中轨、上轨、下轨），并通过DRAWTEXT、DRAWNUMBER等函数显示股票基本信息（所属板块、概念、总股本、流通股本、PE、换手、量比、涨幅等），无买入/卖出条件判断、无CROSS函数、无FILTER函数、无DRAWICON函数。

用法

这是一个布林带指标（参数20,2）： - **中轨（MIDA）**：20日简单移动平均线，代表中期趋势 - **上轨（UB）**：中轨+2倍标准差，代表短期压力位 - **下轨（LB）**：中轨-2倍标准差，代表短期支撑位 - **使用方法**：当价格运行在上轨与下轨之间，可观察价格与上下轨的关系判断超买超卖（触及上轨可能超买，触及下轨可能超卖），结合其他指标综合判断 - **注意事项**：该公式仅作为技术分析参考，不直接给出买卖信号，需自行结合其他分析方法判断入场时机
