如何使我的脚本适用于Macd和ema的买卖指标,作为松树脚本中的条件

所以我的pine脚本有问题,我刚开始使用pine脚本,因此在浏览了此处的一些相关问题的答案后,我想出了一个修改过的脚本,但由于我的脚本可以执行什么操作,所以我遇到了一些问题我希望它能卖出指标,但不能满足我买指标的要求。

基本上,我希望它在我的macd跨过我在脚本上绘制的ema以下时显示卖出指标,并且仅当macd跨过ema时它才应该向我显示买入信号。 请参见下面的脚本。

//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)

当我现在用buySig = not isLong and (d_macdUp) and (close > out)取出零件并用buySig = not isLong and (d_macdUp)替换零件时,卖出信号根据我想要的方式显示,但buySig的代码相反时则不显示sellSig的代码。

我需要的是一个脚本,该脚本的工作方式与我删除那段代码并注释掉plotshape的买入信号时的卖出指标一样。我需要同时根据指定条件显示买卖指标。

最终找到了解决该问题的替代方法。

我分别在行中添加了 and (d_macd >0)进行购买,反之亦然。

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