Supertrend from tradingview to prorealtime

ok I want to convert this tradingview indicator into a prorealtime indicator and I don’t care about it being fancy is just want the buy and sell signals to be clear

study(“Supertrend V1.0 – Buy or Sell Signal”, overlay = true)

Factor=input(7.20112, minval=1,maxval = 100)
Pd=input(2, minval=1,maxval = 100)

Up=close-(Factor*atr(Pd))
Dn=close+(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)
plotarrow(Trend == -1 and Trend[1] == 1 ? Trend : na, title=”Down Entry Arrow”, colordown=red, maxheight=60, minheight=50, transp=0)

something keeps changing when I paste the code so here goes the link to the indicator from tradingview

I’m trying to change the ‘hl2’ to ‘close’ also the factor to ‘7.20112’ and the period to ‘2’

highly appreciated
