Tradingview to mt4 indicator

i want to convert a tradingview indicator into mt4. I will paste the code of the indicator. 

ONLY WORKS ON HEIKEN ashi, so code heiken ashi so that this indicator bases data from within the charts, and alert will ONLY BE GENERATED AT BAR CLOSURE, hence the trade will be executed on the new bar  forming provided that the condition is met. Mt4 doesnt support heiken ashi hence i am saying that i only want heiken ashi chart data to be used to generate the above. I am attaching the code below to be used to convert it into mt4 indicator. i want up and down arrows to show on mt4 chart.

study("Supertrend V1.0 - Buy or Sell Signal", overlay = true)

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)

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