loops - Pine 循环中未声明的标识符

Question

我有这个代码：

// 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

如您所见，我只想在看涨趋势中获得所有渗透。编译器说high_pen var 没有在“ sum = high_pen + injection ”语句中声明。这是一个非常简单的循环，它只需要对渗透进行求和。

我怎样才能正确地做到这一点？我应该如何声明 high_pen 变量并在循环后使用它？

Answer 1

无法验证，因为您的代码段是部分的，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
