Pine 循環中未聲明的標識符

Question

我有這個代碼：

// 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

如您所見，我只想在看漲趨勢中獲得所有滲透。 編譯器說high_pen var 未在“ sum = high_pen + 滲透”語句中聲明。 這是一個非常簡單的循環，它只需要對滲透進行求和。

我怎樣才能正確地做到這一點？ 我應該如何聲明high_pen 變量並在循環后使用它？

Answer 1

無法驗證，因為您的代碼片段是部分的，但這應該有效：

// 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
