无法使用参数调用 'operator /'

Question

我无法正确输入公式。我有以下错误：

第 28 行：无法使用参数 'expr0'='totalRevenueBySampling' 调用 'operator /'。使用了 'fun_ref[totalRevenueBySampling]' 类型的参数，但需要 'const int' 无法使用参数 'expr1'='totalOperatingExpensesBySampling' 调用 'operator /'。使用了 'fun_ref[totalOperatingExpensesBySampling]' 类型的参数，但需要 'const int'；第 28 行：在范围 'Rs' 中找不到变量 'Rs'，无法注册副作用

这是一个脚本看起来：

Kr = Ra / Rs，其中 Ra = Sa / Ea，其中 Rs = Ss / Es

这是我写的脚本：

//@version=5
indicator("Competitiveness")

// Ra (effectiveness from operations)
// Sa - Total Revenue
// Ea - Total Operating Expenses
Ra() =>
    Sa = request.financial(syminfo.tickerid, "TOTAL_REVENUE", "FQ")
    Ea = request.financial(syminfo.tickerid, "TOTAL_OPER_EXPENSE", "FQ")
    Ra = Sa / Ea

// Rs (effectiveness from operations by sampling)
// Ss - Total Revenue by Sampling
// Es - Total Operating Expenses by Sampling
sym1 = input.symbol("", "Ticker")
sym2 = input.symbol("", "Ticker")

Ss() =>
    obj1 = request.financial(sym1, "TOTAL_REVENUE", "FQ")
    obj2 = request.financial(sym2, "TOTAL_REVENUE", "FQ")
    totalRevenueBySampling = math.avg(obj1, obj2)
    
Es() =>
    obj1 = request.financial(sym1, "TOTAL_OPER_EXPENSE", "FQ")
    obj2 = request.financial(sym2, "TOTAL_OPER_EXPENSE", "FQ")
    totalOperatingExpensesBySampling = math.avg(obj1, obj2)

Rs() =>
    Rs = Ss / Es

// Kr (effectiveness from operations ratio)
Kr() =>
    Kr = Ra / Rs

plot(Kr(), "Kr", color.aqua, 2)

我哪里错了？

Answer 1

将 () 添加到您的函数调用中。

Rs() =>
    Rs = Ss() / Es()

// Kr (effectiveness from operations ratio)
Kr() =>
    Kr = Ra() / Rs()

无法使用参数调用 'operator /'

Cannot call 'operator /' with argument
