如何获得特定日期的收盘价 [英] How to get close price of a specific date

问题描述

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.

My code below plots a horizontal line at the close price of a date entered by me. However it works only with 'Daily' time frame on chart. I need it to work in any time frame(Mainly 15 minute time frame). For any other time frame, it doesn't plot the actual closing price. Instead it plots the closing price of the last candle.

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.

I tried the security function, but I cannot use it inside if condition. But if condition is my requirement to validate the date entered by me.

//@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)

推荐答案

试试这个例子作为参考:

Try to use this example as a reference:

//@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)
