Pine- 脚本/交易视图无法获得正确的代码以获得高 + 缓冲值答案

【问题标题】：Pine- Script/ Trading View Not able to get the proper code for getting high + buffer valuePine- 脚本/交易视图无法获得正确的代码以获得高 + 缓冲值

【问题描述】：

我正在尝试使用 Pine 脚本执行策略，其中应匹配以下条件并执行 long ：

条件：发生交叉（ema10，ema20）和（（交叉的高+缓冲区）交叉（ema10，ema20））。我无法获得 longentry，您能帮忙解决这个问题吗？

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, linewidth = 1, 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, location=location.belowbar, color=green, text="longentry", size=size.small)
plot(ema10, title="Ema 10", color = green, linewidth = 1, transp=1)
plot(ema20, title="Ema 20", color = red, linewidth = 1, transp=1)
