Answer 1

第62行包含未来函数：drawline
第65行包含未来函数：drawline
很遗憾，测试代码包含未来函数！

Answer 2

楼上的不太准确，drawline在一般的测试软件上都显示成未来函数，其实它没有多大的危害！不过楼主得小心，凡是太准确的公式都不能过于的相信，有那种公式，炒股还需要技术吗？都按照公式来炒股，那还不乱套了啊，你自己多多考虑吧。

Answer 3

很可惜，最后的买进判读中，最后一个条件是未来函数。
源码REF(DOWN,1)<REF(DOWN,2) AND UP>REF(DOWN,1)
up和down的定义中，barslast函数属于未来函数的一种，用来定义筛选周期。

Answer 4

我大致看了看，感觉没有，你再问问别人。
