Keltner system from TradingView to ProRealTime?

I have this Keltner-channel system code that I would like to translate to ProRealTime and backtest, would it be possible for anyone to assist me with this?

//@version=4
strategy(“Keltner Channel Strategy”, overlay=true)
source = close

useTrueRange = input(true)
length = input(20, minval=1)
mult = input(1.0)

ma = sma(source, length)
range = useTrueRange ? tr : high – low
rangema = sma(range, length)
upper = ma + rangema * mult
lower = ma – rangema * mult

crossUpper = crossover(source, upper)
crossLower = crossunder(source, lower)

bprice = 0.0
bprice := crossUpper ? high+syminfo.mintick : nz(bprice[1])

sprice = 0.0
sprice := crossLower ? low -syminfo.mintick : nz(sprice[1])

crossBcond = false
crossBcond := crossUpper ? true
: na(crossBcond[1]) ? false : crossBcond[1]

crossScond = false
crossScond := crossLower ? true
: na(crossScond[1]) ? false : crossScond[1]

cancelBcond = crossBcond and (source < ma or high >= bprice )
cancelScond = crossScond and (source > ma or low <= sprice )

if (cancelBcond)
strategy.cancel(“KltChLE”)

if (crossUpper)
strategy.entry(“KltChLE”, strategy.long, stop=bprice, comment=”KltChLE”)

if (cancelScond)
strategy.cancel(“KltChSE”)

if (crossLower)
strategy.entry(“KltChSE”, strategy.short, stop=sprice, comment=”KltChSE”)

//plot(strategy.equity, title=”equity”, color=color.red, linewidth=2, style=plot.style_areabr)
