Mt4 conversions from pinescript code

Can you do mt4 conversions from pinescript code ?

//@version=2
strategy("Exponential", overlay=true)
src = input(ohlc4, title = "source")
len = input(21, title = "timeframe / # of period's")
e = ema(src,len)
evar = (src - e)*(src - e)
evar2 = (sum(evar,len))/len
std = sqrt(evar2)
Multiplier = input(2, minval = 0.01, title = "# of STDEV's")
upband = e + (Multiplier * std)
dnband = e - (Multiplier * std)
//SL = input(defval=50, minval=0, maxval=10000, title="Stop loss in ticks (leave zero to skip)")
//tradeSize = input(defval=1, minval=1, title="Trade size")

longCondition = crossover(src,e)
if (longCondition)
strategy.entry("My Long Entry Id", strategy.long)

//if( 0 != SL )
//strategy.exit("EXIT BUY", "BUY", qty=tradeSize, loss=SL)
//strategy.exit("EXIT SELL", "SELL", qty=tradeSize, loss=SL)
shortCondition = crossunder(src,e)
if (shortCondition)
strategy.entry("My Short Entry Id", strategy.short)

plot(e, color = purple, linewidth = 2, title = "basis")
plot(upband, color = red, linewidth = 2, title = "up band")
plot(dnband, color = green, linewidth = 2, title = "down band")
