如何从5m图表中获取指标末值

Question

您好，我可以只取当天的指标结算值来计算第二天的结算值吗？(示例:标准差值，如图所示)

谢谢

Indicator Close value

Answer 1

newDay = change(time("D")) != 0
sd = stdev(close, 20)
sdDailyClose = valuewhen(newDay, sd[1], 0)

这将为您提供前一天的收盘价。

如果您想要eod的值，您需要知道时间范围和会话的结束时间。假设下午3:30关闭(15:30)

var float closingSD = na
var int minutes = timeframe.isintraday ? 30 - timeframe.multiplier : na
sd = stdev(close, 20)
closingBarTime = timestamp(year, month, dayofmonth, 15, minutes)
if time >= closingBarTime and barstate.isconfirmed
    closingSD := sd

如果你只打算在5m图表上使用它，你可以将它简化为

var float closingSD = na
sd = stdev(close, 20)
closingBarTime = timestamp(year, month, dayofmonth, 15, 25)
if time >= closingBarTime and barstate.isconfirmed
    closingSD := sd
