松树环中未声明的标识符

Question

我有这样的代码：

// Average penetration

high_pen = for i = 0 to penetration_len

    penetration = high[i] - shortEma[i]
    sum = high_pen + penetration
    high_pen = penetration > 0 ? sum : 0
    high_pen

average_high_pen = high_pen / penetration_len

正如你所看到的，我只是想在一个看涨的趋势中获得所有的渗透。编译器说high_pen变量不是在"sum = high_pen +渗透“语句中声明的。这是一个非常简单的循环，它只需对穿透量进行求和。

我如何才能正确地做到这一点？我应该如何声明high_pen变量并在循环之后使用它？

Answer 1

无法验证，因为您的代码片段是部分的，但这应该有效：

// Average penetration

high_pen = 0.
for i = 0 to penetration_len
    penetration = high[i] - shortEma[i]
    sum = high_pen + penetration
    high_pen := penetration > 0 ? sum : 0

average_high_pen = high_pen / penetration_len
