所以我的 pine 脚本有问题，我刚开始使用 pine 脚本，所以在浏览了一些相关问题的答案后，我想出了一个修改后的脚本，但我遇到了一些问题，因为我的脚本做了我想要的当谈到卖出指标时，它并没有给我我想要的买入指标。

基本上，我希望它在我的 macd 穿过我在脚本上绘制的 ema 下方时显示卖出指标，并且只有当 macd 穿过 ema 时它才应该向我显示买入信号。请参阅下面的脚本。

//input
emaLength = input(200, minval=1, title ="Length")
srce = input(close, title="Source")
offset = input(title="Offset", type=input.integer,  defval=0, minval=-500, maxval=500)
out = ema(srce,emaLength)
macd_default = input(title="macd length", type=input.integer, defval=9, minval=1)
fast_l = input(title="Fast length", type= input.integer, defval=12)
slow_l = input(title="Slow length", type= input.integer, defval=26)

//calculations
fast_ma= ema(close, fast_l)
slow_ma= ema(close, slow_l)
macd = fast_ma - slow_ma
amacd = ema(macd, macd_default)
d_macd = macd - amacd

// Deternine if we are currently LONG
isLong = false
isLong := nz(isLong[1], false)

// Determine if we are currently SHORT
isShort = false
isShort := nz(isShort[1], false)


halfMod =  out % 2

d_macdUp = crossover(d_macd, 0)

d_macdDwn = crossunder(d_macd, 0)


//creating conditions for crosses above ema and below ema for both buy and sell indicators
buySig = not isLong and (d_macdUp) and (close > out)
sellSig = not isShort and (d_macdDwn) and (close < out)

if (buySig)
    isLong := true
    isShort := false

if (sellSig)
    isLong := false
    isShort := true
    

//plot the shape of the indicators and colors
//plotshape(series=buySig, text="BUY", style=shape.triangleup, location=location.belowbar, color=color.green, size=size.small)

plotshape(series=sellSig, text="SELL", style=shape.triangledown, location=location.abovebar, color= color.red, size= size.small)

//plot the ema to visualise the process
plot(out, title="EMA", color= color.blue, offset = offset)

plot(close)

当我现在取出零件buySig = not isLong and (d_macdUp) and (close > out)并将其替换为 时buySig = not isLong and (d_macdUp)，卖出信号会根据我想要的方式显示，但当代码与buySig代码相反时则不会sellSig。

我需要的是一个脚本，当我取出那段代码并注释掉plotshape买入信号时，它的工作方式与卖出指标的工作方式相同。我需要根据指定的条件显示买入和卖出指标。

最终找到了解决这个问题的方法。

我 and (d_macd >0)分别在行中添加了一个用于购买，反之亦然的出售

buySig = not isLong and (d_macdUp) and (close > out)
sellSig = not isShort and (d_macdDwn) and (close < out)
