如何根据条件为真触发标签,但只有一次
How to trigger a label based on a condition being true, but only once
我是 Pine 脚本的新手,请多多包涵。我试图弄清楚如何在“多头”条件变为真时绘制购买标签,但这只是第一次,而不是对于条件为真的每个柱。所以基本上,“strategy.entry”和“strategy.close”以相同的方式打开和关闭单个仓位。
if (longConditions)
strategy.entry("Long", true)
longLabel = label.new(
x=bar_index,
y=na,
text="Long",
xloc=xloc.bar_index,
yloc=yloc.belowbar,
color=color.green,
textcolor=color.white,
style=label.style_label_up,
size=size.normal)
if (closeLongConditions)
strategy.close("Long")
closeLongLabel = label.new(
x=bar_index,
y=na,
text="Close",
xloc=xloc.bar_index,
yloc=yloc.abovebar,
color=color.red,
textcolor=color.white,
style=label.style_label_down,
size=size.normal)
有没有办法让“strategy.entry”和“strategy.close”触发标签而不是我的“长”和“关闭”条件?
这是解决方法
if (longConditions and strategy.position_size < 0)
strategy.entry("Long", true)
longLabel = label.new(
x=bar_index,
y=na,
text="Long",
xloc=xloc.bar_index,
yloc=yloc.belowbar,
color=color.green,
textcolor=color.white,
style=label.style_label_up,
size=size.normal)
if (closeLongConditions and strategy.position_size>0)
strategy.close("Long")
closeLongLabel = label.new(
x=bar_index,
y=na,
text="Close",
xloc=xloc.bar_index,
yloc=yloc.abovebar,
color=color.red,
textcolor=color.white,
style=label.style_label_down,
size=size.normal)
