通达信『趋势画线主图』指标，一眼看穿个股强弱与支撑压力
公式介绍与使用方法
这款趋势画线主图指标是兼具个股强弱对比与自动趋势画线的全能型主图公式，核心覆盖板块个股强弱判定、多周期支撑压力画线、DKX多空线三大核心功能。
使用时，主图左上角会显示个股所属板块及行业排名，同时标注“板块强/弱”“个股强/弱”，直观对比个股与板块、指数的涨幅差异；指标自动绘制短压/短撑、巨量平台、长期压力/支撑、辅助压力线，清晰标注关键价位，股价突破压力线时会出现买入图标提示；下方DKX多空线搭配带状填充，红色代表多头占优，蓝色代表空头主导，辅助判断趋势方向。
实操中，可重点关注股价突破短压、巨量平台、长期压力等关键画线位置的量能配合，结合DKX多空线多头排列信号布局；若显示“个股弱于板块”，需警惕补跌风险。
总结
1. 核心功能：同步展示板块个股强弱对比+自动绘制多周期支撑压力线+DKX多空趋势判断；
2. 关键信号：股价突破压力线的图标提示、DKX多空带颜色变化是核心操作参考；
3. 使用技巧：结合量能验证关键价位突破有效性，规避“个股弱于板块”的标的。
