适合日线以下 任何周期 中间直接调用 日线数据 不过每天要把画面切换到 日线周期 刷新一个昨日的日线数据

还有注意费率设置 要改成期货 15% 合约单位 按该品种自己调整 手续费自己调整

input:k(0.7,0.1,1,0.1);
predayhigh:=callstock(stklabel,vthigh,6,-1);//昨日最高价
predaylow:=callstock(stklabel,vtlow,6,-1);//昨日最低价
predayclose:=callstock(stklabel,vtclose,6,-1);//昨日收盘价
predayrange:=max(predayhigh-predayclose,predayclose-predaylow);//取大波动值
dayopen:=callstock(stklabel,vtopen,6,0);//今天开盘价
upperband:intpart(dayopen+k*predayrange),colorred;//区间上沿
lowerband:intpart(dayopen-k*predayrange),colorgreen;//区间下沿

下日波动:max(callstock(stklabel,vthigh,6,0)-callstock(stklabel,vtclose,6,0),callstock(stklabel,vtclose,6,0)-callstock(stklabel,vtlow,6,0))*0.7;

谢谢楼主！

再请教楼主，这一句好像没用着：

下日波动:max(callstock(stklabel,vthigh,6,0)-callstock(stklabel,vtclose,6,0),callstock(stklabel,vtclose,6,0)-callstock(stklabel,vtlow,6,0))*0.7;

下日波动是让你今天收盘后看的 对于明天的突破区间心理有个底
