我无法从pine脚本中获取今天的回溯日期。我已经定义了从当前时间减去UNIX时间戳的函数。但是以下代码会导致错误"Timestamp requires integer parameter than series parameter"
getdate() =>
tt = timenow - 1549238400
yr = year(tt)
mt = month(tt)
dt = dayofmonth(tt)
timestamp(yr[0], mt[0], dt[0], 0 ,0)
任何帮助将不胜感激。

似乎是松木的不一致性。如果准确性不是那么重要,我建议对时间戳使用selfwriten函数:
//@version=3
study("Timestamp")
MILLISECONDS_IN_DAY = 86400000
TIMESTAMP_BEGIN_YEAR = 1970
myTimestamp(y, m, d) =>
years = y - TIMESTAMP_BEGIN_YEAR
years * MILLISECONDS_IN_DAY * 365.25 + (m - 1) * 30 * MILLISECONDS_IN_DAY + (d - 1) * MILLISECONDS_IN_DAY
// TEST:
tmspm = myTimestamp(2019, 3, 5)
y = year(tmspm)
m = month(tmspm)
d = dayofmonth(tmspm)
plot(y, color=green)
plot(m, color=red)
plot(d, color=maroon)
顺便说一句,timenow
返回一个以毫秒为单位的值,而您尝试将它与以秒为单位的值相减:1549238400
我不完全了解您代码的逻辑,因为您要减去两个日期,然后将该差值转换为新日期。对我而言,这毫无意义。但这也许只是stackoverflow的一个例子,所以不用担心
UPD:您的代码将无法工作,因为您将timenow减去1549238400,但是29天前(以毫秒为单位)为2505600000。 我希望接下来的代码会有所帮助:
//@version=3
study("My Script")
_MILLISECONDS_IN_DAY = 86400000
_29_DAYS_MILLIS = 29 * _MILLISECONDS_IN_DAY
reqDate = timenow - _29_DAYS_MILLIS
reqYear = year(reqDate)
reqMonth = month(reqDate)
reqDay = dayofmonth(reqDate)
linePlotted = false
linePlotted := nz(linePlotted[1], false)
vertLine = na
col = color(red, 100)
//this puts a line exactlty 29 day ago or nothing if there wasn't a trading day at the date. If you want to put a line 29 days ago or closer, then:
// if year >= reqYear and month >= reqMonth and dayofmonth >= reqDay and not linePlotted
if year == reqYear and month == reqMonth and dayofmonth == reqDay and not linePlotted
linePlotted := true
vertLine := 1000
col := color(red, 0)
plot(vertLine, style=histogram, color=col)
请注意,有两种可能的条件取决于您的需要:在29天前准确地放置一行(如果当天没有任何小节,则不行),并且必须在该日期或更接近今天的位置放置一条直线

round
函数将其转换为整数?[0]
等后面删除yr
