以下代码属于 v2 版本。我需要更新到 v5 版本，但我知道的不多，我很困惑。你能帮助我吗？

//Settings

主要变化是：

  • 将新input.int()功能用于用户输入integer类型
  • 使用新的命名空间ta和math
  • 使用新color.new()功能创建具有透明度的颜色

这是v5：

//Settings

needlong = input(true, "long")

needshort = input(true, "short")

needstops = input(false, "stops")

stoppercent = input.int(5, minval = 1, maxval = 50, title = "Stop, %")

usefastsma = input(true, "Use fast MA Filter")

fastlen = input.int(5, minval = 1, maxval = 50, title = "fast MA Period")

slowlen = input.int(21, minval = 2, maxval = 200, title = "slow MA Period")

bars = input.int(2, minval = 0, maxval = 3, title = "Bars Q")

needbg = input(false, title = "Need trend Background?")

needex = input(true, title = "Need extreme? (crypto/fiat only!!!)")

fromyear = input.int(1900, minval = 1900, maxval = 2100, title = "From Year")

toyear = input.int(2100, minval = 1900, maxval = 2100, title = "To Year")

frommonth = input.int(01, minval = 01, maxval = 12, title = "From Month")

tomonth = input.int(12, minval = 01, maxval = 12, title = "To Month")

fromday = input.int(01, minval = 01, maxval = 31, title = "From day")
