01 趋势是散户的提款机，但90%的人抓不住它“趋势来时，猪都能飞上天；趋势去时，雄鹰也会折翼。”许多散户盯盘10小时，却总在一买就跌、一卖就涨中循环——缺的是看清趋势的眼睛👀。今天分享的通达信波段指标，像给K线装上导航仪🧭，震荡市也能稳抓主升浪。
02 指标核心：用三根线看透波段密码🔹 波段生命线 UPPER/LOWER原理：8日最高/最低动态画上下轨，像给股价套安全绳🪢实战：触UPPER回落→高压区；触LOWER反弹→黄金坑
源码片段TC1:=IF(H=HHV(H,8*UR),H,DRAWNULL);UPPER:=CONST(IF(TC2=1,H,REF(H,TC2-1)));
🔹 多空分界岭 STICKLINE颜色⚪ 白色：多头掌控⚫ 灰色：空头占优口诀：白线不破坚持做，灰线缠绕快撤退
🔹 买卖点双星 买线/卖线📈 买线(EMA4)上穿卖线(EMA35)＝红箭头买入📉 卖线死叉买线＝绿箭头逃顶例：2025-04 AI龙头X，红箭头后5日涨18%
03 案例解析：2025实战“指标神迹”🔥 案例1 新能源逆袭战标的：宁德时代 2025-06信号：LOWER三日不破，STICKLINE转白，金叉出现结果：15日获利23%
🔥 案例2 AI龙头逃顶记标的：科大讯飞 2025-05信号：天线78.89触发“逃顶”，死叉出现结果：次日跌停，规避30%回撤
04 实战应用：手机党三步战法🕘 早盘9:30：看STICKLINE颜色，灰色防守🕑 午盘14:00：买线是否金叉，确认尾盘挂单🌙 收盘复盘：标记UPPER/LOWER触点，画箱体
个人经历：3月用此法做半导体ETF，灰转白建仓，4月吃鱼身🐟
05 指标适配适合股性：波段趋势股（新能源、AI应用层）适合人群：上班族、纪律派、稳健型慎用：连板妖股、ST、期指
