'time' 不是变量声明中的有效类型关键字

Question

我正在遵循 PineCoders 为 Pine 制定的最佳实践，我意识到没有 time 这样的类型。出现以下情况怎么办？

'time' is not a valid type keyword in variable declaration

请注意，我可以轻松地从 i_startDateTime 和 i_endDateTime 中删除 time 前缀并解决问题，但我希望它使用最佳实践。就像 LucF goy 所做的那样 https://www.tradingview.com/script/Xh8tLDTe-Delta-Volume-Realtime-Action-LucF/.

var string START_TIME = "2018-01-01T00:00"
var string END_TIME = "2030-01-01T00:00"

var string GP12 = "Date range filtering"
bool    i_dateFilter = input(false, "Date Range Filtering", group = GP12)
time    i_startDateTime = input(timestamp(START_TIME), "Start Date/Time", type = input.time, group = GP12)
time    i_endDateTime = input(timestamp(END_TIME), "End Date/Time", type = input.time, group = GP12)

f_tradeDateIsAllowed() => i_dateFilter ? (time >= i_startDateTime and time <= i_endDateTime) : true

Answer 1

timestamp()函数returns和int，所以你的变量也必须声明为int，或者在定义时省略int变量。

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

var string START_TIME = "2018-01-01T00:00"
var string END_TIME   = "2030-01-01T00:00"

var string  GP12            = "Date range filtering"
var bool    i_dateFilter    = input(false, "Date Range Filtering", group = GP12)
var int     i_fromDate      = input(timestamp(START_TIME), "Start Date/Time", type = input.time, group = GP12)
var int     i_toDate        = input(timestamp(END_TIME),   "End Date/Time",   type = input.time, group = GP12)
