问题描述
我正在尝试使用Pine脚本执行策略，该脚本应满足以下条件并应执行长时操作：
条件：发生交叉（ema10，ema20）和（（交叉（ema10，ema20）的（（交叉的上限+缓冲区的上限））））。 我无法参加，请您帮忙解决这个问题？
下面是我的代码：
study("Crossover and highcrossover",overlay=true)
ema10 = ema(close,10)
ema20 = ema(close,20)
psar = sar(0.02,0.02,.2)
crossoverval = crossover(ema10,ema20)
signalhigh = iff(crossoverval == 1,high,na)
highbufferadd = signalhigh + 3.0
plot(signalhigh,title="signalhigh",color = green,linewidth = 1,transp=1)
plot(highbufferadd,title="highbufferadd",color = yellow,transp=1)
longentry = crossoverval and (close > highbufferadd)
plotshape(series=crossoverval,title="Crossover",style=shape.arrowup,location=location.belowbar,color=green,text="Crossover",size=size.small)
plotshape(series=longentry,title="longentry",style=shape.triangleup,text="longentry",size=size.small)
plot(ema10,title="Ema 10",transp=1)
plot(ema20,title="Ema 20",color = red,transp=1)
解决方法

ema20 = ema(close,20)

signalhigh = iff(crossoverval == 1,high,na)
highbufferadd = signalhigh + 3.0

plot(highbufferadd,title="highbufferadd",color = color.yellow,transp=1)
