Many thanks

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


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


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)
//plot(Trend==1 and Trend[1]==-1,color = linecolor, style = circles, linewidth = 3,title="Trend")

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

The auto convert tool works starting from v3 . So, you need to update it to v3 yourself and then let the tool do its job.

The only thing you need to pay attention to is self referenced variables are removed .

//@version=5
indicator('Supertrend V1.0 - Buy or Sell Signal', overlay=true)

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

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

TrendUp = 0.0
TrendUp := close[1] > TrendUp[1] ? math.max(Up, TrendUp[1]) : Up
TrendDown = 0.0
TrendDown := close[1] < TrendDown[1] ? math.min(Dn, TrendDown[1]) : Dn

Trend = 0.0
Trend := close > TrendDown[1] ? 1 : close < TrendUp[1] ? -1 : nz(Trend[1], 1)
Tsl = Trend == 1 ? TrendUp : TrendDown

linecolor = Trend == 1 ? color.green : color.red

plot(Tsl, color=linecolor, style=plot.style_line, linewidth=2, title='SuperTrend')

plotshape(ta.cross(close, Tsl) and close > Tsl, 'Up Arrow', shape.triangleup, location.belowbar, color.new(color.green, 0), 0)
plotshape(ta.cross(Tsl, close) and close < Tsl, 'Down Arrow', shape.triangledown, location.abovebar, color.new(color.red, 0), 0)
//plot(Trend==1 and Trend[1]==-1,color = linecolor, style = circles, linewidth = 3,title="Trend")

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