只有那些被黄色包围的信号才会被期望。
study(title="ALMA", overlay=true)
alma = alma(close, 9, 0.85, 6)
plot(alma, title="ALMA", color=color.yellow, linewidth=2)
ema50 = ema(close,50)
plot(ema50, title="EMA", color=color.fuchsia, linewidth=2)
A = close > alma
B = close < alma
var S_sell = false
var S_buy = false
if (A)
S_sell := true
S_buy := false
if (B)
S_Sell := false
S_buy := true
plotshape(A,text="Buy",style=shape.flag,size=size.small,offset=0,color=color.green,textcolor=color.green,location=location.belowbar)

可以使用设置为1的barssince()函数。
//@version=4
study(title="ALMA", overlay=true)
alma = alma(close, 9, 0.85, 6)
ema50 = ema(close,50)
plot(alma, title="ALMA", color=color.yellow, linewidth=2)
plot(ema50, title="EMA", color=color.fuchsia, linewidth=2)
A = close > alma
B = close < alma
plotshape(barssince(A)==1,text="Buy",style=shape.flag,size=size.small,offset=0,color=color.green,textcolor=color.green,location=location.belowbar)
plotshape(barssince(B)==1,text="Sell",style=shape.flag,size=size.small,offset=0,color=color.red,textcolor=color.red,location=location.abovebar)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
