Question

我下面的代码在我输入的日期的收盘价处绘制了一条水平线。但是，它仅适用于图表上的“每日”时间范围。我需要它在任何时间范围内工作（主要是 15 分钟时间范围）。对于任何其他时间范围，它不会绘制实际收盘价。相反，它绘制了最后一根蜡烛的收盘价。

我尝试了安全功能，但无法在 if 条件下使用它。但如果条件是我验证我输入的日期的要求。

//@version=4
study("How to get actual close price for a specific date", overlay=true)

text = input(false, type=input.bool, title="---------------------Select Date--------------------------")
startDate = input(title="Date", type=input.integer,
     defval=12, minval=1, maxval=31)
startMonth = input(title="Month", type=input.integer,
     defval=5, minval=1, maxval=12)
startYear = input(title="Year", type=input.integer,
     defval=2021, minval=1800, maxval=2100)
     
Time_start = timestamp(syminfo.timezone, startYear, startMonth, startDate, 00, 00)
Time_end = timestamp(syminfo.timezone, startYear, startMonth, startDate, 23, 59)

pinDateRange = time >= Time_start and time <= Time_end

var pclose = 0.00
if pinDateRange
    pclose := close
    // pclose := security(syminfo.tickerid, 'D', close)
        
plot(pclose, title="Close Price of Selected Date", color=#F94D00, linewidth=1, style=plot.style_stepline, offset=-9999, trackprice=true)

尝试使用此示例作为参考：

//@version=4
study("Plot value starting n months/years back", "", true)
monthsBack = input(3, minval = 0)
yearsBack  = input(0, minval = 0)
fromCurrentDateTime = input(false, "Calculate from current Date/Time instead of first of the month")

targetDate = time >= timestamp(
  year(timenow) - yearsBack, 
  month(timenow) - monthsBack,
  fromCurrentDateTime ? dayofmonth(timenow) : 1,
  fromCurrentDateTime ? hour(timenow)       : 0,
  fromCurrentDateTime ? minute(timenow)     : 0,
  fromCurrentDateTime ? second(timenow)     : 0)
beginMonth = not targetDate[1] and targetDate

var float valueToPlot = na
if beginMonth
    valueToPlot := high
plot(valueToPlot)
bgcolor(beginMonth ? color.green : na)
