版本1至Pinescript中的版本5

Question

我正在尝试将以下列表从版本1转换为版本5。我被卡在了突出显示的步骤中。我需要在版本5中使用此代码，因为我必须将此代码与我的另一个版本5代码合并。任何人都可以帮我将以下代码转换为版本5。

Factor=input(3, minval=1,maxval = 100)
Pd=input(7, minval=1,maxval = 100)


Up=hl2-(Factor*atr(Pd))
Dn=hl2+(Factor*atr(Pd))


//Need help in the below part
**TrendUp=close[1]>TrendUp[1]? max(Up,TrendUp[1]) : Up
TrendDown=close[1]<TrendDown[1]? min(Dn,TrendDown[1]) : Dn
Trend = close > TrendDown[1] ? 1: close< TrendUp[1]? -1: nz(Trend[1],1)
Tsl = Trend==1? TrendUp: TrendDown**

linecolor = Trend == 1 ? green : red

plot(Tsl, color = linecolor , style = line , linewidth = 2,title = "SuperTrend")

plotshape(cross(close,Tsl) and close>Tsl , "Up Arrow", shape.triangleup,location.belowbar,green,0,0)
plotshape(cross(Tsl,close) and close<Tsl , "Down Arrow", shape.triangledown , location.abovebar, red,0,0)

plotarrow(Trend == 1 and Trend[1] == -1 ? Trend : na, title="Up Entry Arrow", colorup=lime, maxheight=60, minheight=50, transp=0)
plotarrow(Trend == -1 and Trend[1] == 1 ? Trend : na, title="Down Entry Arrow", colordown=red, maxheight=60, minheight=50, transp=0)```

Answer 1

您需要知道的更改被解释在这里。

基本上，您需要先声明变量。

//Need help in the below part
TrendUp = 0.0
TrendUp := close[1]>TrendUp[1]? max(Up,TrendUp[1]) : Up

TrendDown = 0.0
TrendDown := close[1]<TrendDown[1]? min(Dn,TrendDown[1]) : Dn

Trend = 0
Trend := close > TrendDown[1] ? 1: close< TrendUp[1]? -1: nz(Trend[1],1)
Tsl = Trend==1? TrendUp: TrendDown
