精选通达信主图指标之最佳画线（源码分享）
精选通达信主图最佳画线源码分享，解析关键指标配置。源码r源 趋势射线配置如下：趋势射线3X: DRAWLINE(L=LLV(L,安卓3),L,C=HHV(C,3),L,0),COLOR9AFF;
趋势射线7: DRAWLINE(H=HHV(H,7),H,L=LLV(L,7),L,0),COLOR9AFF;
射线7X: DRAWLINE(L=LLV(L,7),L,H=HHV(H,7),L,0),COLOR9AFF;
趋势射线: DRAWLINE(H=HHV(H,),H,L=LLV(L,),L,0),COLORCFF;
射线X: DRAWLINE(L=LLV(L,),L,H=HHV(H,),L,0),COLORCFF;
趋势射线: DRAWLINE(H=HHV(H,),H,L=LLV(L,),L,0),COLORCB;
射线X: DRAWLINE(L=LLV(L,),L,H=HHV(H,),L,0),COLORCB;
趋势射线: DRAWLINE(H=HHV(H,),H,L=LLV(L,),L,0),COLORYELLOW;
射线X: DRAWLINE(L=LLV(L,),L,H=HHV(H,),L,0),COLORYELLOW;
上述配置通过计算历史最高价、最低价与当前价格之间的源码r源php源码6关系，形成多条趋势线，安卓用于辅助分析趋势强度。源码r源论坛注册登录源码 关键点识别逻辑如下：A1至D1、安卓D定义了高点识别逻辑，源码r源通过比较当前价格与历史价格的安卓高低点，绘制蓝色高点线。源码r源
A2至D2、安卓T、源码r源U定义了低点识别逻辑，安卓直销官网源码类似地，源码r源绘制蓝色低点线。安卓
M参数用于计算更长周期的锁机超强源码高点和低点识别，绘制红色高点线和红色低点线，以提供更长远的趋势指引。
最后的fabric 更新通道 源码VAR至VAR部分使用了比较与交叉逻辑，通过计算历史最高价与最低价，并与当前收盘价进行比较，确定压力位与支撑位，以辅助交易决策。 以上代码展示了通达信主图的高级画线技巧，通过综合多条趋势线与关键点识别，为投资者提供了直观且丰富的市场分析工具。在实际应用中，需结合具体市场情况和交易策略进行调整与优化。2024-12-23 00:222387人浏览
