需要幫助將 PineScript a v2 轉換為 v4。 我的知識有限，因此不勝感激

Question

我已經有這個腳本有一段時間了，我想把它轉換成 v4，但我很難用它。 我知道有一個轉換按鈕，但這僅適用於 v3+。 腳本一點也不長，如果有人能幫助我，我真的很感激，或者指出我的方向，因為我對 pinescript 的了解非常薄。 感謝大家

len = input(title="Length", type=integer, defval=3)
len1 = input(title="Length1", type=integer, defval=1)

TrueRange = max(max(high-low, abs(high-nz(close[1]))), abs(low-nz(close[1])))

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

讓我們 go 到 V5。

//@version=5
indicator('ADX')
len = input(title='Length', defval=3)
len1 = input(title='Length1', defval=1)
th = input(title='threshold', defval=20)

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

SmoothedTrueRange = 0.0
SmoothedDirectionalMovementPlus = 0.0
SmoothedDirectionalMovementMinus = 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 = math.abs(DIPlus - DIMinus) / (DIPlus + DIMinus) * 100
ADX = ta.sma(DX, len)

crosscall = DIPlus > DIMinus
crossput = DIMinus > DIPlus
DIPcross = ta.sma(crosscall ? 1 : 0, len1)
DIPput = ta.sma(crossput ? 1 : 0, len1)
DIPOVB = DIPlus > 60
DIMOVS = DIMinus > 60

bgcolor(DIMOVS ? color.lime : na, transp=40)
bgcolor(DIPOVB ? color.orange : na, transp=20)
plot(DIPlus, color=color.new(color.green, 0), linewidth=3, title='DI+')
plot(DIMinus, color=color.new(color.red, 0), linewidth=3, title='DI-')
plot(ADX, color=color.new(color.white, 0), linewidth=1, title='ADX')
hline(th, color=color.white, linewidth=1, linestyle=hline.style_dashed)
bgcolor(DIPcross ? color.green : na, transp=60)
bgcolor(DIPput ? color.red : na, transp=60)
