在绘图命令中添加时间变量

Question

抱歉，我的编码太生疏了，我正在尝试找出 pinescript。

我试图添加时间变量的简单脚本。 目标是仅在 RTH（纽约交易时间）内显示情节。

我已经了解到“IF 语句必须位于绘图命令内，而不是相反”，但我似乎无法再进一步了。 请帮忙。

study("Pivot High Low Points", overlay =true)

t = time(timeframe.period, "0930-1600")
time_cond = not na(t)

lb = input(defval = 5, title="Left Bars")
rb = input(defval = 5, title="Right Bars")

mb = lb + rb + 1

plotshape(iff(not na(high[mb]), iff(highestbars(mb) == -lb, high[lb], na), na), style = shape.triangledown, location = location.abovebar, color = color.red, size = size.tiny, offset = -lb)  
plotshape(iff(not na(low[mb]), iff(lowestbars(mb) == -lb, low[lb], na), na), style = shape.triangleup, location = location.belowbar, color = color.lime, size = size.tiny, offset = -lb)

问题是，如何将“if and time_cond”插入到plotshape命令中？ 谢谢！

想不通。 不会编译

Answer 1

将 if 条件分配给变量，然后使用

and

time_cond

。

high_cond = iff(not na(high[mb]), iff(highestbars(mb) == -lb, high[lb], na), na)
low_cond = iff(not na(low[mb]), iff(lowestbars(mb) == -lb, low[lb], na), na)

high_plot = high_cond and time_cond
low_plot = low_cond and time_cond

plotshape(high_plot, style = shape.triangledown, location = location.abovebar, color = color.red, size = size.tiny, offset = -lb)  
plotshape(low_plot, style = shape.triangleup, location = location.belowbar, color = color.lime, size = size.tiny, offset = -lb)

注意： 由于您在

offset

中使用了

plotshape()

，因此您可能需要根据需要调整时间条件。
