pine-script - 如何从系列[整数]制作常量字符串

Question

我正在尝试打印 mondayAll 的值，因为它是一系列整数，所以我采用最新的值（mondayAll[0]）。尽管如此，还是会发生此错误： Cannot call 'string' with 'x'=series[integer]. The argument should be of type: const string;

var int mondayLong = 0
var int mondayAll = 0
// ---------------------------

if(dayofweek == dayofweek.monday)
    mondayAll := mondayAll + 1
    if(close > open)
        mondayLong := mondayLong + 1

val = mondayAll[0]
text1 = "Monday All: " + string(val)
l1 = label.new(bar_index,high[0],text=text1)
label.delete(l1[1])

知道如何解决这个问题吗？

Answer 1

改用str.tostring()函数。

//@version=5
indicator("My Script")
var int mondayLong = 0
var int mondayAll = 0
// ---------------------------

if(dayofweek == dayofweek.monday)
    mondayAll := mondayAll + 1
    if(close > open)
        mondayLong := mondayLong + 1

val = mondayAll[0]
text1 = "Monday All: " + str.tostring(val)
l1 = label.new(bar_index,high[0],text=text1)
label.delete(l1[1])

plot(close)
