Convert Tradingview Pinescript into MQL4 EA

Hi,

I need someone to convert this pinescript into EA.

The EA will just close trades (when a buy / sell signal is triggered), and print red / green channel.

Parameters:

- G-trend length

- show / hide channel

Indicator "G-trend" on tradingview :

length = input(100),src = input(close)
//----
a = 0.,b = 0.
a := max(src,nz(a[1])) - nz(a[1] - b[1])/length
b := min(src,nz(b[1])) + nz(a[1] - b[1])/length
avg = avg(a,b)
//----
crossup = b[1] < close[1] and b > close
crossdn = a[1] < close[1] and a > close
bullish = barssince(crossdn) <= barssince(crossup)
c = bullish ? color.lime : color.red
//plot(a,"Upper",color=color.blue,linewidth=2,transp=100)
//plot(b,"Lower",color=color.blue,linewidth=2,transp=100)
p1=plot(avg,"Average",color=c,linewidth=1,transp=90)
p2=plot(close,"Close price",color=c,linewidth=1,transp=100)
fill(p1,p2,color=c,transp=90)
 
showcross = input(true)
plotshape(showcross and not bullish and bullish[1] ? avg : na, location=location.absolute, style=shape.labeldown, color=color.red, size=size.tiny, text="Sell", textcolor=#ffffff, transp=0, offset=-1)
plotshape(showcross and bullish and not bullish[1] ? avg : na, location=location.absolute, style=shape.labelup, color=color.lime, size=size.tiny, text="Buy", textcolor=#ffffff, transp=0, offset=-1)
