标题：【提问】加variable和不加variable好像没有区别？
1楼

老师，您好。

我试了以下代码：

==========================
test:=0
VARIABLE: vtest=0;
GLOBALVARIABLE: gtest=0;

debugout('tp1: test = %.2f', test);
test:=1;
debugout('tp2: test = %.2f', test);

debugout('tp1: vtest = %.2f', vtest);
vtest:=1;
debugout('tp2: vtest = %.2f', vtest);

debugout('tp1: gtest = %.2f', gtest);
gtest:=1;
debugout('tp2: gtest = %.2f', gtest);
==========================

输出结果是:


tp1: test = 0.00
tp2: test = 1.00

tp1: vtest = 0.00
tp2: vtest = 1.00

tp1: gtest = 0.00
tp2: gtest = 1.00
运行结束

tp1: test = 0.00
tp2: test = 1.00

tp1: vtest = 0.00
tp2: vtest = 1.00

tp1: gtest = 1.00
tp2: gtest = 1.00
运行结束

这样看来，有没有VARIABLE效果是一样的，每次循环这个变量都会别初始化，对吗？


谢谢！

这个是在同一根k线上才是这的样，同一根k线数据还没有被计算，

你到第二根k线看看输出结果，variable的那个是不是都是1了

第二根K线上也不是全1： （怎么看后台程序用的是什么周期的k线？我在设置里设的应该是1分钟线）

以下是真实的打印结果（test就是vtest）：

？test不是全局变量，是普通变量，每根k线都会被重新赋值成0，这个不明白？

cathero2001 发表于：2014/6/3 15:34:45
“（test就是vtest）”

这里的test就是vtest，真实的代码是这个：


VARIABLE: test=0;
GLOBALVARIABLE: gtest=0;

debugout('tp1: test = %.2f', test);
test:=1;
debugout('tp2: test = %.2f', test);

debugout('tp1: gtest = %.2f', gtest);
gtest:=1;
debugout('tp2: gtest = %.2f', gtest);


谢谢~：）

好吧。

代码：
VARIABLE: test=0;
GLOBALVARIABLE: gtest=0;

debugout('tp1: test = %.2f', test);
test:=1;
debugout('tp2: test = %.2f', test);

debugout('tp1: gtest = %.2f', gtest);
gtest:=1;
debugout('tp2: gtest = %.2f', gtest);
