Question

每天有没有一种方法可以区分不同的颜色？例如，11月9日图表的背景颜色为红色，而11月10日图表的背景颜色为绿色，依此类推，随着新日子的增加，它们会获得不同的颜色或重复的颜色模式吗？

好听的问题:)
这应该可以显示您要查找的内容。

//@version=4
study("DayColors", overlay=true)

var color c0     = input(color.silver, "Sunday",    type=input.color)
var color c1     = input(color.red,    "Monday",    type=input.color)
var color c2     = input(color.orange, "Tuesday",   type=input.color)
var color c3     = input(color.yellow, "Wednesday", type=input.color)
var color c4     = input(color.green,  "Thursday",  type=input.color)
var color c5     = input(color.blue,   "Friday",    type=input.color)
var color c6     = input(color.purple, "Saturday",  type=input.color)
var int   transp = input(60, "Background transparancy", minval=0, maxval=100)

var arrColor     = array.new_color()

if barstate.isfirst
    array.push(arrColor, c0)
    array.push(arrColor, c1)
    array.push(arrColor, c2)
    array.push(arrColor, c3)
    array.push(arrColor, c4)
    array.push(arrColor, c5)
    array.push(arrColor, c6)

bgcolor(array.get(arrColor, dayofweek-1), transp)

编辑：根据注释中的要求，仅应用从“市场开盘”到“市场收盘”的颜色。

var int   t        = na

if barstate.isfirst
    array.push(arrColor, c0)
    array.push(arrColor, c1)
    array.push(arrColor, c2)
    array.push(arrColor, c3)
    array.push(arrColor, c4)
    array.push(arrColor, c5)
    array.push(arrColor, c6)

t := time(timeframe.period, sess)

bgcolor(na(t) ? na : array.get(arrColor, dayofweek-1), transp)
