如何将Pinescript版本2转换为版本4/5？

Question

如何将以下脚本转换为v5？

study("ADX/DI Histogram",overlay=false,scale=scale.left)

len = input(title="Length", type=integer, defval=14)
th = input(title="threshold", type=integer, defval=25)

TrueRange = max(max(high-low, abs(high-nz(close[1]))), abs(low-nz(close[1])))
DirectionalMovementPlus = high-nz(high[1]) > nz(low[1])-low ? max(high-nz(high[1]), 0): 0
DirectionalMovementMinus = nz(low[1])-low > high-nz(high[1]) ? max(nz(low[1])-low, 0): 0

SmoothedTrueRange = nz(SmoothedTrueRange[1]) - (nz(SmoothedTrueRange[1])/len) + TrueRange
SmoothedDirectionalMovementPlus = nz(SmoothedDirectionalMovementPlus[1]) - (nz(SmoothedDirectionalMovementPlus[1])/len) + DirectionalMovementPlus
SmoothedDirectionalMovementMinus = nz(SmoothedDirectionalMovementMinus[1]) - (nz(SmoothedDirectionalMovementMinus[1])/len) + DirectionalMovementMinus

DIPlus = SmoothedDirectionalMovementPlus / SmoothedTrueRange * 100
DIMinus = SmoothedDirectionalMovementMinus / SmoothedTrueRange * 100
DX = abs(DIPlus-DIMinus) / (DIPlus+DIMinus)*100
ADX = sma(DX, len)
ve=DIPlus>(DIMinus+(DIPlus*10)/100)
ro=DIMinus>(DIPlus+(DIMinus*10)/100) and ADX>11 and ADX<=25
xve= DIPlus>(DIMinus+(DIPlus*10)/100) and ADX>22
xro=DIMinus>(DIPlus+(DIMinus*10)/100) and ADX>22
fl=DIPlus-DIMinus<abs(10) and ADX<15

di=25+(DIPlus-DIMinus)

cr = ADX <= 22 ? color(green, 80) : ADX <= 34 ? color(green, 60) : ADX <= 46 ? color(green, 35) : ADX <= 58 ? color(green, 5) : ADX <= 70 ? color(green, 0) : color(green, 0)
cg = ADX <= 22 ? color(maroon, 80) : ADX <= 34 ? color(maroon, 60) : ADX <= 46 ? color(maroon, 35) : ADX <= 58 ? color(maroon, 5) : ADX <= 70 ? color(maroon, 0) : color(maroon, 0)
//adxgrad = ADX <= 22 ? color(gray, 60) : ADX <= 34 ? color(gray, 50) : ADX <= 46 ? color(gray, 40) : ADX <= 58 ? color(gray, 30) : ADX <= 70 ? color(gray, 20) : color(gray, 0)

plot(di,style=columns,linewidth=4,color=di >= 25 ? cr : cg,transp=50,histbase=th,title="DI")
plot(di,style=line,linewidth=2,color=di >= 25 ? cr : cg,transp=50,histbase=th,title="DI Line")
plot(ADX, color=black, linewidth=1,transp=0, title="ADX")

请参阅迁移指南将您的代码升级到V3。手动执行此操作后，您可以使用自动转换器工具将其升级为V4和V5。

To upgrade your code to v3, you should know some changes like

要修复自我引用，您可以做：

SmoothedTrueRange = 0.0
SmoothedTrueRange := nz(SmoothedTrueRange[1]) - (nz(SmoothedTrueRange[1])/len) + TrueRange

我提供的链接应该为您提供足够的信息。同样，将其升级到V3，然后使用自动转换器工具。
