核心逻辑
这是一个纯绘图类指标，其核心功能是在通达信软件界面上绘制一个坐标网格。该指标使用DRAWRECTREL函数在屏幕特定位置绘制一系列垂直线（KK0-KK10）和水平线（JJ1-JJ20），形成一个网格坐标系。这个网格的垂直线从x=993开始，水平线从y=993开始，构成了一个10x20的格子结构。该指标本身不包含任何技术指标计算，也不使用任何价格或成交量数据，纯粹是为了在界面上显示静态的网格参考线。
买卖信号
该指标不产生任何买卖信号。它只是一个纯绘图函数，没有条件判断逻辑，不涉及任何买入或卖出的触发条件。
用法
这个指标的主要用途是作为其他指标或分析过程的视觉参考框架。交易者可以将其作为背景网格使用，帮助：1）定位价格水平位置；2）作为自定义指标的坐标系；3）在编写其他指标时作为定位参考。在实际交易分析中，通常需要结合其他具有实际计算逻辑的技术指标一起使用。
